What type of drills to choose for processing wood, metal, plastic


The main advantage of any decorative panels is their simple installation, and if we talk about plastic panels, then you can also add very simple processing and adjustment. Plastic is a fairly soft material that can be cut with almost anything - I mean, almost every first cutting tool will do. Despite this, the issue of cutting plastic has its own subtleties and nuances, which, among other things, we will get acquainted with in this article, in which, together with the site stroisovety.org, we will deal with the question of how to cut plastic panels?

How to cut plastic panels: four tools and what to expect from them

What can most often be found in the arsenal of any master finisher? Naturally, the most popular tool in work. Among it there will probably be a razor-sharp knife, a hacksaw for metal, wood, and perhaps even an electric jigsaw. It is the listed tools that are most often used for cutting plastic panels. All these tools cut differently, but be that as it may, they do it, and the quality of the cut is quite sufficient for finishing walls.

  1. Knife. It should be quite sharp and be able to cut through one side of the panel in one pass. In fact, in the process of cutting plastic with a knife, the master cuts only its front surface - then the panel is simply broken, after which the back side is cut off again with a knife. Everything is simple, but the cut itself turns out to be uneven and one side of the plastic seems to be bent, which makes it difficult to insert a strip of PVC panel into the starting profile or connector. You have to trim everything and achieve a normal edge, wasting time on this process.
  2. Wood saw. It has large teeth and in most cases does not cut plastic panels, but tears them along the edges. In general, this option is not very successful and it is better to leave it as a last resort when nothing else is at hand.

By and large, if you are not bothered by the melted edges of the panels, you can cut this material using a grinder. As an option, a circular saw is also suitable, but for this it will need to be equipped with a circle with a fine tooth. In general, anything will do, but you need to understand that some tools create ragged edges, while others make a clean, but not entirely even cut.

Many of the visitors to this site, including myself, like to improve and repair their cars themselves. And probably many have encountered the fact that some problems have to be solved using “collective farm” methods: all sorts of screws, twists, electrical tape, and other crap begin to appear. “Somehow sloppy!”

Today I want to present several less common tools and materials that fit well into automotive specifics and can help solve some problems very elegantly, which doubles the pleasure from the work done)

1. Crimping pliers for cable lugs

An indispensable thing for those who like to tinker with electrics. Allows you to organize a reliable, “factory-like” connection between the wire and the tip.

2. Wire stripper

A couple more handy things for electricians. They allow you to easily and accurately strip the wire without damaging the core, including in places with limited access.

3. Drills for plastic

Surely many have encountered the fact that it is not very convenient to drill plastic using ordinary drills (read drills for metal). Often the drill bits and the holes turn out uneven and ugly.

Drills for plastic, having a different geometry and a sharper sharpening angle, eliminate these troubles.

4. Step drills

The same problem that occurs when drilling plastic can occur when drilling sheet metal, and the situation gets worse as the difference between the hole diameter and the thickness of the workpiece increases.

This is where a step drill can come to the rescue. First, a small hole is drilled for the drill to enter, and each subsequent step expands the diameter.

5. Threaded rivets

A very useful thing for organizing threaded fastening in thin-walled parts, such as sheet metal. Can also be used to repair damaged threads.

These rivets are similar to the well-known pull rivets, only they have a thread instead of a setting rod. The installation principle is similar: the rivet is screwed onto the threaded rod of the rivet maker, inserted into the hole, the rod is pulled, the back of the rivet is crushed and the rivet is fixed in the hole.

6. V-Coil Thread Repair Kits

Such a kit can be a great help when the thread is damaged, and changing to a larger thread diameter is impossible or difficult. In addition, it can be used for the transition from inch threads to metric threads, as well as for hardening threads (in parts made of soft metals).

The essence of the repair is as follows: a hole with a broken thread is drilled out to the next diameter and a special tap is used to cut the thread of the next diameter, but with a pitch of the one being repaired. For example: a stripped M4 thread (0.7 pitch) is drilled out to 4.2 mm, and a 5x0.7 thread is cut (while the standard M5 pitch is 0.8 mm). Next, using a mandrel, a special “spring” with a wire cross-section “for the thread” is screwed into this thread. That's it, the spring gets stuck, the inside of its coils becomes a new thread!

7. Gas burner

And finally - heavy artillery. A rusted nut in a suspension is a common occurrence. One of the most effective ways of unscrewing is heating with a gas burner. To help the “home” car mechanic - compact gas burners.

All. I hope someone discovered something new.

How to make a hole in a plastic panel: hole cutting tool

Almost every time we talk about decorating walls or ceilings with plastic panels, we have to face the issue of cutting out holes in the panels for lamps or sockets - separate tools are used for them, although in some cases some of those described above can be used . We will leave them for later, but for now we will figure out the most suitable options.

    Hole saw. An ideal option, but it’s not always available at hand. The most suitable tool is a plasterboard saw, which can cut holes of various diameters by changing attachments - you can choose a saw for both sockets and recessed ceiling lamps. This tool cuts very carefully, but you need to be careful at the end of the drilling - when the tool suddenly falls through the plastic, damage to the main panel can be caused. At this point, the pressure on the tool must be significantly reduced.

This concerns solving the question of how to make a hole in a PVC panel for a lamp or socket using basic tools - in addition to them, as mentioned above, you can use those described above. For example, a knife - in order for the hole to be even, it must first be drawn with a marker or pen (unfortunately, a pencil leaves a barely noticeable mark on plastic). Using exactly the same principle, along a pre-drawn line, a hole can be cut using either a hacksaw blade or an electric jigsaw with a fine-tooth file.

Why are plastic windows drilled?

There are various situations that require drilling holes in a plastic window frame. For example, you need:

  • attach a certain type of slopes to the window structure;
  • mask the installation seams with strips;
  • install a television or internet cable;
  • install blinds;
  • install LED strip and so on.

In many cases, you can play it safe and do without drilling the window, but there are situations when it is really necessary.

How to make a hole in a PVC panel: secrets of cutting the material

When working with each material there are some features - so to speak, subtleties that are used by craftsmen to achieve one or another goal. Regarding plastic panels, among such nuances the following points can be highlighted.

  1. Cross cut During its production, using a corner will help create a cut at a clear angle of 90 degrees.
  2. Longitudinal cut The simplest cut, since it is made between internal reinforcing bridges, is in most cases made with a knife. First, the face of the plastic is cut through, then the panel is bent and the back side is cut through.
  3. Another interesting point associated with cutting plastic panels lengthwise is the possibility of lining external and internal corners without the use of special connecting elements. If the panel is cut from the back, it can be easily bent, thereby forming an internal corner. And if you remove the strip between the stiffening ribs from the back side of the plastic, the panel can be bent in the other direction, thereby forming an outer corner. The only thing to remember here is the fragility of plastic - with sudden movements, the thin material can break. Before work, it is better to slightly warm up the bend with a hair dryer - you can even use a household hair dryer.

And the last point concerns the smooth longitudinal cutting of plastic PVC panels. If you need to cut it clearly lengthwise, then it is best to make the cut between the internal bulkheads of the panel - first you can cut it as it turns out, and only then align it along the bulkhead. In principle, there is practically no need to make such precise and clear cuts - except when you have to hide the last strip in the starting profile. A clear cut without any burrs is important here.

To conclude the topic of how to cut plastic panels, I will say a few words about the quality of cutting. Do not underestimate the importance of an even cut when installing plastic panels - you should not count on the edges being hidden behind the starting profile. The fact is that a crooked cut is primarily a problem when installing the panel. It is much easier to insert an evenly cut strip of plastic. Moreover, by inserting a crookedly cut panel, you run a high risk of damaging other cladding elements with the tool that you will use to insert the strip into the profile.

Hello readers and subscribers of my channel. I think every craftsman knows how to make a hole in plastic (if you need to make a rectangular hole) . The problem is different - the diameter of the drilled hole does not always coincide with the required one. I myself often come across a situation where the hole in the plastic turns out to be slightly smaller than necessary and in order to insert a bolt or other part into it, it is necessary to widen it. Of course, you can use a regular wood file, but it will take a lot of time, and we need to do it quickly.

If you need to expand not 1 mm or 3 mm , then of course you can use a device for an electric drill, which is not at all difficult to invent. To do this, two pieces of sandpaper are inserted into a rod sawn from one end with smooth sides facing each other, and the other end is inserted into the drill chuck. With this device you can not only expand holes in plastic, but also in wood.

If you just need to widen the hole a little, then you don’t need to bother with an electric drill; just cut a wooden stick with a cone with a slightly larger diameter than the diameter of the hole, wrap it with the same sandpaper and twist it. Using sandpaper pressure in about 10 minutes you can expand the hole by 1-3 mm.

I hope these tips were useful to you and you will definitely use them. Have a great mood everyone! Like and don't forget to subscribe to the channel.

In most cases, drilling into wood and plastic is not difficult because these materials are usually soft. Special wood drill bits can be identified by their pointed center tip. There are also no difficulties when using a metal drill to drill wood or plastic. If a large hole is needed, you can pre-drill with a thin drill (diameter up to 4 mm). This operation will help avoid cracking of the wood. Pre-drilling is always necessary when drilling into hard wood. Otherwise, the stainless steel screws may easily break when tightened.

SKIL recommends using work gloves, safety glasses, a dust mask and hearing protection as specified in the owner's manual when operating power tools.

RESULT

The crowns are good, but you must follow certain rules for working with them. The crown I broke was the result of improper use (with a bad head, you can… break the crowbar). The cut holes turn out to be very neat without burrs or torn edges; they cut almost anything, especially thin sheet materials... Cons: shallow depth of the crowns (about 7mm), thick walls.

That's all. All the best!

Feather drill

The tip drill is used to produce large holes with a diameter of more than 11 mm. To ensure a smooth and clean hole, it is best to continue drilling until the tip comes out on the opposite side of the workpiece. After this, the workpiece must be turned over and the operation completed by drilling on the other side. A spade drill has a centering tip and sharp cutting ends on opposite sides of the blade. A point drill bit is used to make large holes in both wood grain and the sawn ends of beams and timbers. When using a spindle drill, you should always set the drilling speed to high.

Drilling HPL plastic

The most suitable drills for plastic are helical drills with sharpening angles of 60 and 80º (as opposed to the 120º drills typically used for drilling metal) and a sharp helical angle (high-speed angle) with a wide drilling gap (wide cut). The recommended tilt angle is 7º and the contact angle is 8º. Holes with a diameter of up to 15 mm can be produced using a screw drill. For drilling holes with a diameter of 15 to 40 mm, expansion drills with one or more blades and a guide are used; for even larger diameters, adjustable circular blades with a guide are used. In the latter case, the hole must be drilled on both sides.

The penetration speed of the drill must be within such limits that the decorative surface of the plastic does not heat up, since heating leads to its damage.

Using a solid wood base underneath prevents the edges of the material from breaking off where the drill exits. In mass production, better results can be obtained by using templates with couplings to rigidly secure the part to be drilled.

IT IS IMPORTANT TO KNOW!

The diameter of the hole for the screw should be 0.5 mm larger than the diameter of the screw itself. The screw should not touch the edges of the hole, and there should be gaps on all sides of the hole so that the material can move slightly if the temperature or humidity changes.

In any case, plastic or rubber spacers should be used to avoid over-tightening the screws. Oval head screws should never be used as this will result in no plastic play.

Both when drilling internal holes and when cutting out, their edges should always be rounded. The inner radius should be as large as possible. If the inner side has a length of up to 250 mm, then the inner corner of the cut should be rounded to a radius of 5 mm. The radius must be increased when cutting holes on the larger, longer side.

Countersink drill

A countersink bit is used to countersink a hole that is necessary to ensure that the head of the screw is flush or slightly recessed into the surface of the wood. The hole is first drilled with a regular drill, after which a countersink drill is used to countersink the hole to the required depth. If it is necessary to make the screw completely invisible, countersink it to a greater depth and then cover the head of the screw with wood-based filler, a plug or a wooden plug.

Hole saw

If you need to drill a hole in wood with a diameter larger than what can be achieved with a spade drill, you must use a hole saw. The cutting edge of a hole saw looks like a band saw rolled into a ring. First, a hole is made using a central drill, which is subsequently drilled using the tape part of the drill. There are also multi-hole saws that are suitable not only for hardwood, but also for brick, drywall, laminated surfaces, plastics and similar materials.
