How to choose a manual pipe die for thread cutting


Why is this even required?

Despite the fact that the 21st century has arrived relatively long ago, and store shelves are full of various modern materials for gas and water pipes, carving as such is still relevant. It has been used for quite a long time, but still there is no reason to refuse its use.

On a note! Of course, polyethylene pipes are connected to each other using compression fittings, while polypropylene pipes are generally soldered. It is not only easy, but also convenient and fast.

However, all plastics (including composites made on their basis) are characterized by two significant disadvantages.

  • Firstly , high temperatures are contraindicated for them. For example, the “ceiling” for polypropylene is only +90 degrees. This is true, you will notice, but in accordance with the standards and requirements, there should not be a higher temperature in the pipelines of residential buildings; That’s right, but in many northern regions, due to cold winters, heating systems have to exceed these standards, otherwise people may simply freeze. And if the temperature in the plumbing/heating system exceeds +100 degrees, that is, the boiling point of water, then polypropylene in this case cannot be used at all. As for PE pipes, the maximum permissible temperature for them is only +40 degrees.
  • Secondly , the mechanical strength of plastics/composites is low. And if the pipeline needs to be laid, say, under a popular road or in a restaurant toilet, where it can be damaged by drunken visitors, then the use of plastic must be abandoned altogether! The same applies to metal-plastic pipes, which can easily be deformed or removed from the fitting.

Important information! If you need a heat-resistant pipeline, we recommend paying attention to copper. Pipes made from it can be used at temperatures from 0 (if the temperature is lower, the water will simply turn into ice) to +250 degrees. However, copper is quite expensive, and due to the fact that pipes made from it have thin walls, its strength under lateral loads is unsatisfactory.

What options are left? Unfortunately, only steel. Preference, of course, is better to give galvanized ones, since there is definitely too much rust in the pipeline.

Note also that there are two ways to achieve a tight connection between steel pipes:

  • use a threaded connection;
  • use welding.

At the same time, not everyone can boast of having a welding machine; in addition, after welding, the protective zinc layer is damaged. And this leads to rusting of the welds. Consequently, such a water supply system will initially have vulnerable spots.

How to choose the right clamp

The price range of these instruments in markets and stores is quite wide. The quality of a product directly depends on the cost. It is necessary to buy an expensive mechanism only if you are a professional, or if as a result of your work you need to obtain high-precision results. When choosing a tool, you need to pay attention to the quality of the steel from which the cutters are made. It is preferable to choose alloyed one. In order for the tool to serve for a long time, it must be purchased with replaceable cutters. Cutters from different manufacturers have different overall dimensions and do not always fit the same die.

The designation included in the model name indicates the diameter of the pipe that can be processed with its help.

Working in awkward or hard-to-reach places can be made easier by using a ratchet socket

What can you use for thread cutting?

If we consider the process from the point of view of labor and time costs, then the best option would be not a pipe clamp, but a lathe. You just need to place the pipe in the spindle, then tighten it, cut off the excess using a cutting tool, straighten the edge, and then, after changing the tool, select the parameters of the required thread. Basically, that's all.

Note! Even in the absence of a cutter, such a machine will make it possible to cut threads using hand tools. Moreover, in this case the tool will not overheat, which is also a definite plus.

But not everyone has the opportunity to use a lathe. Therefore, only hand tools remain - the die and the die discussed in today’s article. But besides these tools, you will also need something to cut the pipe. And this can be done either using a pipe cutter, or using a manual turbine or an ordinary hacksaw for metal.

Which clamp would you choose or would you advise to choose?

Take the survey

Klupp - what is it?

So, a clamp is a fairly effective device used in the installation of pipeline systems. In principle, it is a die that is familiar to us (or a “lerk”, as it is also called). The device consists of a small cylindrical part with a recess for removing chips out during thread cutting. In addition, along the entire perimeter of the tool there is also a recess necessary for comfortable clamping with the help of a holder. Inside the tool there are ridges, which, in fact, form the thread.

What is the difference between the described device and the same die? The fact is that in the first case, only the cutters remained from the die as the main functional part of the device. And they are attached directly to the holder, and it, in turn, serves as a guide.

Where and when a tool is needed

A die is a device for cutting metric, persistent, pipe threads on metal products or other hard materials. This is a metal cylinder with a complex body geometry and removable comb-shaped cutters inside, which make slits in the metal. Unlike a collapsible die, the usual die (in everyday life )
is a monolithic tool, so it is used less and less.

The Klupp belongs to professional thread-cutting equipment, but is used in everyday life as often as in production. The popularity of the device is due to its low price, simplicity of design and ease of use in the most inconvenient places.

Advantages of a die over a simple die

Typically the die is made of expensive tool steel. In this case, only the cutters must be especially strong, because they form the thread. And the die, as we noted earlier, is also a die, but without expensive and non-functional elements. An inexpensive holder, as well as durable cutters, is all that is required in this case.

It would seem illogical to consider the tool as a budget alternative to a die: on the market you can find dies whose cost is measured in thousands of dollars. But do not forget that the cutters here are replaceable elements.

What are the savings anyway? On consumables. As for the tool, its cost is so high for the reason that it makes the thread cutting process less tedious and more convenient.

Video - Pipe clamp: what is it?

The best hand clamps

A manual die is a die with a kind of holder. It is the holder that is the distinguishing feature of various models. The simplest option is a standard knob, the same as that of the die holder. Due to the characteristic features of the application, the die is rarely fixed in one position of the holder. As a rule, this is a removable handle, rotated by changing the hole in the die itself. More expensive models use a ratchet that does not need to be adjusted. Of course, it is more convenient to use, but you should pay special attention to the build quality.

Key varieties of klupp

We should start with the fact that pipe clamps are divided into several groups depending on ease of use and, of course, price. Let's take a closer look at these groups.

Group No1. Simple hand tools

Let's not beat around the bush - we are talking here about the simplest die in a simple holder. Visually there is no difference at all. The round frame is a guide that has clamps for the cutters and a pair of handles necessary for its rotation.

Group No2. Hand tools with ratchet

This design is a slightly more complicated version of the previous one - the frame is equipped with a ratchet, thanks to which it becomes possible not to intercept the handles. You just need to make reciprocating movements with one handle (like pumping water with a pump).

Important information! If you find both the first and second variants of the clutch in the store, but their cost is the same, then it is certainly better to give preference to the first. After all, a ratchet in tandem with cheap Chinese production (read: the use of low-quality metals) is a very dangerous combination, which you should definitely stay away from.

Group No3. Electrical tools

But in this case, all the work with the device consists of correctly installing the pipe and pressing the appropriate button. The electric drive will handle everything else perfectly. Having a fairly modest power (estimated at only a few hundred watts), such tools are capable of developing great force, which is possible due to the significant transmission coefficient on the gearbox.

Rules for using the tool

Both manual and electric models of the clamp are quite easy to use. At the same time, there is a small but mandatory set of rules for the performer of the work, ensuring the quality of the thread, the convenience of the worker and the safety of the tool.

When cutting threads with a die, significant torque and bending moments act on the pipe, so the tool must be securely fastened to the pipe through a guide; additional fastening may be necessary for the pipe itself.

The quality of the thread largely depends on the correct entry of the cutters, for which a lead-in chamfer must be made at the end of the pipe - depending on the diameter and thickness of the pipe wall using a file, grinder, chamfer cutter or rolling with a hammer. The clamp, like other metal-cutting tools, should be used with a lubricant and cooling fluid. It will be much easier to cut threads with a die using waste oil, grease or cleaning fluid.

Pipe clamp selection criteria

At the moment, the industrial industry has developed so much that clamps are sold in a huge assortment and in a variety of modifications. Russian markets are replete with a variety of products, including those made in the West, which in most cases are of higher quality. As for specific prices, we will talk about them a little later, we will only note that they, as well as the choice, have a considerable spread. When choosing the tool described in the article for yourself, be sure to consult with a qualified specialist in advance. In any case, it is better not to give preference to the cheapest tool, as well as to the first outlet you come across. Subsequently, such a die will most likely unpleasantly surprise you - both with its “outstanding” capabilities and with further failure. At the same time, the price (especially in the case of purchasing a pipe clamp) increases along with the quality of the tool.

An equally important parameter is, of course, replaceable cutters. After all, if these elements can be changed if necessary, then you will not have to completely change the entire device in the future. But it may also happen that new cutters will not fit the die, and therefore it is recommended to purchase them directly with the equipment.

Finally, when choosing a die, pay attention to the fact what is the material used to make the pipes on which the threads will be cut. Pay attention to what exactly the incisors are made of. The most reliable (and therefore the most popular) option is, of course, alloy steel.

Types of clumps

In the technical literature and among manufacturers, there is no unified classification of screws for thread cutting, as well as the need for it. Suitable tools for different types and volumes of work, as well as for different types of pipe material, can be selected at any specialized tool store. The selection parameters are the pipe diameter and the purpose of the connection, which determine the type and diameter of the thread. The choice of manual or electric execution of the clamp depends on the volume of work, its one-time, periodic or professional nature. This quality can also be affected by the availability of power supply at the work site.

A few important nuances

The use of a pipe clamp, as well as any other tool, has its own nuances.

  1. Before starting work, the pipe must be rolled (the same as with a die). There are many ways to make one end of the pipe a little thinner - using a file, turbine, etc.; You can also just take a hammer and flatten the end a little using an anvil. Another common option is a general one using a gas key.
  2. If the pipe where the thread is to be cut is part of an existing pipeline, then it must be held with a gas wrench in order to compensate for the rotating moment during threading.
  3. And if you apply a little grease or even ordinary diesel fuel to the future cutting site, the threads will not become scuffed; on the contrary, it will be easier to cut, and the cutters themselves will last much longer.
  4. Finally, if you buy new cutters, try to choose the same manufacturer that made the holder. If not, then you may encounter a problem - the incisors simply will not fit into place.

Pros and cons of the tool

It is important for a potential buyer to know the advantages and disadvantages of a tool before purchasing so as not to make a mistake with the choice.

Let's look at the pros and cons below.

pros

  1. Low cost. Due to the division of tools into two categories - household and professional - the cost is different. The increase in price is caused by design changes, such as the presence of a ratchet, electric drive, or large housing. The household appliance is smaller in size, its price will be lower, but you need to use a pipe wrench to rotate it.
  2. Durability. Due to the subtleties of the equipment design, the cutting element can be removed, then cleaned and even replaced. The wear of such material will be lower due to the direction of the cutting element - it moves in a spiral, which makes the depth more uniform.
  3. Flexibility of application. Clupps can be used everywhere - in the gas industry, in the installation of water and heat supply systems, sewage systems, and the like.
  4. Ease of repair. Thanks to the ability to remove the cutters, owners of professional dies are able to change one or two elements of the entire structure without changing the entire product.
  5. You need to put in less effort. Electric variations of the die, due to their electric drive with a gearbox, make it easier to cut threads.

Minuses

  1. Hardly ever. The tool is simply perfect for performing its “duties” of creating or repairing threads.

Important! To work properly with the tool, you need to have a lot of free space around the pipe. If, for example, the width is 80 mm or more, then the radius of rotation of the order will be approximately 4 cm.


A quality tool has plenty of advantages

Popular models of dies, characteristics and prices

On a note! As you can see, pipe clamps are relatively cheap, and there are really plenty to choose from on the modern market. The specific cost depends on the diameter, technical characteristics and, of course, the specific manufacturer.

How the device works

A die is a type of die – a tool for cutting external threads on cylindrical parts. These types of tools differ in design and purpose.

A die from the arsenal of turners, mechanics and metal cutters is designed for manual and machine cutting of metric or pipe threads. It is a solid or split steel nut with an axial cutting edge corresponding to the thread profile and radius chip holes. The materials for making the dies are alloyed chromium and high-speed steels or hard alloys. In height, the cutting edge includes 6-8 turns of a conical profile, 2-3 of which are lead-in. Its use is possible in a workshop or with a lathe. To operate, the die is installed in a holder or a special machine chuck using grooves and conical holes on the side faces.

A die for cutting threads on pipes is a mounting tool and is considered a detachable or sliding (multiple) die. The cutting edge of the die is made on removable plates made of the same types of steel, which are secured in the body with the help of nuts and screws. The installation of cutters must be carried out in accordance with their numbering, corresponding to the offset of the thread pitch of each of them. The die design also includes a guide corresponding to the diameter of the pipe being processed. Handles or a ratchet with a ratcheting mechanism can be used to rotate the tool during operation.

Master Class. Threading a pipeline using a pipe clamp

The procedure should begin with cutting the pipe (you can use a grinder for this). It is important that the cut is as smooth as possible, otherwise you will not be able to screw anything onto such a thread. In short, this needs to be taken care of in advance. If you don’t know how to use an angle grinder, you’ll have to learn it yourself.

The cutting procedure itself, as we have already found out, is not anything overly complicated. You just need to prepare everything you need and follow the step-by-step instructions below.

To begin with, we repeat, you need to cut the pipe evenly. We have already found out everything about this, so we are moving on to the next stage.

After this, it is necessary to remove the chamfer, otherwise it will be extremely difficult to screw anything onto the resulting thread (for example, the same fittings). To remove the chamfer, use a small grinder - sharpen the pipe so that its edge is at an angle of approximately 45 degrees. The accuracy of this angle is not critical, but it is necessary for the thread to have a really high-quality start.

Note! A few words need to be given to the condition of the pipeline. Cutting new threads is in most cases required where the steel pipe is prone to rotting. Examine it for wall thickness and, if it is too small, it is better to completely abandon threading in this area. Otherwise, you will further weaken the already weak area, and it will therefore rot faster.

Now let's get back to the workflow itself. So that the tool “goes” better on the metal, the latter must be lubricated. You can use absolutely any lubricant for this purpose (even sunflower oil and lard). Next, put the device on the pipe (in this case, a simple ratchet clamp is used), and then adjust the ratchet so that it can rotate counterclockwise quite freely. Apply gentle pressure to the tool to “start the process.” In the future, when he “bites” the steel, the work will go faster, and therefore there will be no need to press anything.

The cutting procedure itself must be performed in stages. Proceed approximately as follows: first of all, cut the first turn, then rearrange the ratchet and turn the device in the opposite direction (this is necessary in order to chop off the chips). And if you neglect this recommendation, then you will have to make serious efforts to cut. In this way, stage by stage, cut.

Now you are probably asking a logical question: how much should you cut? The answer is simple - all the teeth of the tool must be on the pipe. For what reason? There is nothing complicated: the die is made in such a way that with each new turn the metal is cut to a specific depth. To obtain a high-quality and “finished” thread, so to speak, it is necessary that all the teeth of the tool, without exception, are involved in the process. In short, if you cut a 5mm thread, you are unlikely to be able to screw on the fitting properly.

Having cut to the end, move the ratchet to the “reverse” direction and twist it from the pipe. After this, you can check how to screw a faucet, fitting, or whatever you need onto the freshly made thread. The check must be thorough!

Note! During cutting, we recommend holding the pipeline with an adjustable wrench, as was probably mentioned earlier. This way the riser will not break or turn. Also, don’t make the carving too low to the floor surface - you won’t be able to achieve this anyway!

A few more words about the principle of operation - useful recommendations

Summarizing all of the above, let's briefly go over the main stages of thread formation again (the procedure with a regular pipe, and not an existing pipeline, will be described here).

Stage one . First you need to take the pipe and carefully fix it using special clamps.

Stage two . After this, the end of the pipe where the thread will be made must be thoroughly cleaned, lubricated with something, and then the device knob installed there.

Stage three . Next, the device must be rotated, applying considerable effort. This must be done until the thread of the required parameters is obtained.

It should also be noted that using the tool described in the article you can cut both metric and inch threads. It is quite obvious that in the first case it is measured in millimeters, and in the second - in inches.

To extend the service life of the die, we recommend adhering to the requirements presented below.

  • Replace parts of the tool that are already worn out in a timely manner.
  • When choosing a tool, take into account the parameters of the product on which the thread will be cut. It is important that both fit each other in size. And if the die is smaller than the pipe, then during operation strong friction will be generated, due to which the cutters can be deformed.
  • Periodically, the device needs to be lubricated, for which a special lubricant is used. The latter is necessary in order to cool the incisors. This way you will protect them from overheating and, as a result, deformation.

As a result, we note that the clamp is a professional tool, and therefore it should be handled in accordance with the operating rules. When choosing a particular device model, you must understand how it operates and what manipulations can be performed with its help. Knowing what material the pipe is made of, what its dimensions and technical characteristics are, you can choose the right tool from a wide modern range. And if you also use it carefully, you will ensure that the die will maintain good condition and original characteristics.

That's all. Be sure to watch the topical video below. Good luck!

What are these construction tools for?

The areas of application of the mechanism are varied: heat supply, water supply, laying sewer pipes, gas supply. In addition, the product is used in the following cases:

  1. If the need arises, build prefabricated structures: light stairs, greenhouses, gazebos, and so on.
  2. When installing a heating system, when you need to connect metal and polypropylene elements.
  3. When laying a water supply network. The tool will help you make cuts on cast iron, copper and metal products, including those made of stainless steel.
  4. An integral device when drilling wells and wells.
  5. Without the device it is impossible to lay a sewer system.

Before cutting, it is necessary to clean the area of ​​rust and paint. The clamp must fit freely in the space between the wall and the pipes. The elements are cut off with a grinder after careful marking.

As for the rest of the equipment, they do not amaze the imagination with the presence of unusual elements, but buyers like them for access to spare elements. The kit is packed in a plastic container, which is somewhat confusing, because the design looks somewhat flimsy. This is why we recommend purchasing a stronger case for carrying the tool.

The clamps are made of steel; the manufacturer did not provide more detailed information on its product, however, a large number of positive reviews and comments eliminate all doubts about the purchase.

Yato YT-29001

The Polish manufacturer provides the buyer with an excellent product at a very reasonable price. Manufacturing products in Europe obliges plants and factories to comply with standards and GOSTs, which means that the operation of the tool guarantees excellent results in the most difficult cases. The model has all the necessary documents, and all quality certificates are also present.

The material used is high-quality and strong steel. The kit includes additional dies and a durable carrying case. The ergonomic handle made of polyurethane will allow you to carry out repair work for a long time without load.

And another Chinese representative. It is also difficult to find useful information about him. As for the steel from which the tool is made, it is also difficult to find details here. At the same time, the company is in great demand in the market, users leave entirely positive reviews. It is difficult to assume that they were all purchased. Conclusion: a minimum of information is not a reason to refuse to purchase a fully functional tool. Klupp is capable of serving for a long time, but cannot cope with serious and complex tasks.

This Chinese model compares favorably with its analogues. Firstly, the brand accurately indicated the material of the die – durable and prepared steel. Nine elements are ergonomically arranged in a shock- and drop-resistant case. There are convenient holders and a ratchet. Another big advantage of the model is its compliance with standards. The price is higher than that of analogues, but the quality justifies the cost, since the unit is equipped with everything necessary for operation.
