History of origin
Chainsaws were first discovered in 1920. The devices were equipped with targets with flat and straight teeth, which made them not very effective and the process too labor-intensive. 27 years later, Joseph Cox invented a new type of design, characterized by an L-shaped appearance, which significantly increased the productivity of the product and simplified the sharpening process.
Cox's invention removed all competitors from the market in a short time, and continues to hold a leading position to this day. Today, all popular models are equipped with just such systems. Their main feature is a crescent-shaped cutting profile, which allows them to cope with various types of wood.
It is worth noting that the concept developed by Joseph Cox was so successful that for many decades it has not undergone any fundamental changes. Only the lubrication system has been improved, the return flow has been improved and vibration has been minimized.

What are there
Any saw chain for a chainsaw has three types of links:
Varieties | Description |
Connecting | Connects leading and cutting elements. |
Presenters | People call them “shanks”. Thanks to the drive sprocket, rotation is transmitted to the structure from the engine, which ensures its precise position on the tire. |
Cutting | Quite a complex device. It consists of a cut depth limiter and a cutting element where there is a contour cutting angle. |
The main one is considered to be the cutting link. They are made right- and left-handed. Incisors are divided into two types:
- Chisel. They are distinguished by high productivity and excellent cutting speed. The configuration provides a smaller contact area with the wood, which helps reduce surface resistance. The main disadvantage is excessive sensitivity to abrasives, as well as difficulty in sharpening.
- Chipper. It features an increased contact area, which reduces cutting efficiency. The main advantage is ease of maintenance. The main area of use is cutting contaminated wood.
Types of saw chains depending on the type of cutting links
The working links are equipped with teeth that cut wood. The convenience of sharpening and productivity depend on their shape. Let's look at the two most common options.
Chisel chains
If you look at the link in cross-section, you will see a clear profile reminiscent of the number “7”. People call such a saw set “seven” . Due to the smooth end surface and sharp corners, quick cutting of wood is ensured. The cut is precise and uniform. This type of chain is used in professional chainsaws. But it is difficult to sharpen it - the slightest deviation from the plane leads to beveled corners.
Chisel cutting link.
Chains with chipper cutting links
Here, the cross-sectional shape of the link resembles a sickle, which is why people call this type of equipment . ” When driven into wood, the teeth contact the material in larger areas than a chisel type, which increases the load and slows down the cutting speed. But if the headset gets dirty, the performance characteristics are not reduced - it needs to be cleaned much less often. This type of chain is also easier to sharpen, since it does not require maintaining even angles.
Chipper cutting link.
How to choose the best option
Every owner of a chainsaw, no matter how carefully he worked with the tool, was faced with the need to replace the sawing device. Popular models differ in the configuration and thickness of the links, pitch, average price and other characteristics.
The chain and guide bar belong to the category of replaceable equipment, so when purchasing budget options, you can replace these elements with more wear-resistant and durable ones. Changing the headset to a longer one will help improve efficiency, but this will only work if you have sufficient engine power and the rotation element. To avoid mistakes when choosing, it is worth getting advice from specialized experts.
Material for making cutting links
When choosing accessories for a chainsaw, it is important to visually check the correct shape and sharpness of the teeth. But it also requires proper selection of the chain according to the material of manufacture, which affects its service life. There are two common types.
High alloy chromium-nickel steel
Most saw chains are made from this material. They are suitable for felling forests, harvesting firewood, artistic wood carving, building houses from logs or timber, etc. But when they come into contact with denser materials, they quickly become dull or even become unusable.
Saw chain made of high-alloy chromium-nickel steel.
Carbide tipped
When it is necessary to process heavily frozen materials, very hard or with increased contamination, chains with carbide tipped teeth are used. They have increased wear resistance, which extends the life of the equipment under heavy loads. The presence of special carbide tips on the chain is indicated by corresponding markings on each tooth.
Carbide-tipped saw chain.
Tire classification
Manufacturers produce products that differ in size. The main parameter of a saw chain is considered to be the number of links. The length of the product depends on this indicator. In addition, the systems have a specific step. Its indicator is the distance between links connected in series, divided in half. Let's look more specifically at each parameter.
Step by step
It is customary to distinguish the following classes:
- 0.25 (1/4"). It's called a "small step". These designs are installed on one-handed chain saws with low power, but high accuracy and the ability to use in hard-to-reach places.
- 0.325 (3/8"). The most common models. The lion's share of products are equipped with this type of headset.
- 0.404 (3/4"). Powerful tools with high productivity are equipped, such as harvesting equipment, felling systems, and so on.
Shank thickness
The parameter must match the groove of the bar. This increases the reliability of the fit and prevents it from falling off during operation. In this case, the movement will be smooth, without excessive vibration and sudden movements. Branded products are produced with the following values:
Parameters (mm) | Purpose |
1,1 | Small chains for mini saws. |
1,3 | Used for household and semi-professional chainsaws. |
1,5 | More powerful tools are available. |
1,6 | Designed for professional saws. |
2,0 | Industrial saws are equipped. |
Cutting depth, profile height, engine capacity
What should you pay special attention to when choosing a product? Precisely on this data. The height of the cutting edge varies, and therefore a distinction is made between low-profile and high-profile designs. The latter are distinguished by excellent performance, the former by an increased support area of the cutting link, which has a positive effect on operational safety.
Cutting depth affects productivity. The larger it is, the stronger the vibration. To balance the performance of products with large pitches, they are equipped with cutting teeth with a shallow depth. The most popular gaps are 0.025" and 0.03". Designs with a value of 0.07” have found their use in felling timber on an industrial scale.
Engine size plays an important role when choosing the optimal unit. If you install a saw chain on a tool with significant power, then increased loads will soon damage it and you will have to buy a new one. Therefore, before purchasing a new headset, it is necessary to review the technical characteristics of the saw.
Material
The rating of quality products is always topped by representatives made from wear-resistant material. According to buyers, this is an important aspect when making a final decision, along with design features and functionality. Household and professional units use high-quality designs at a significant price and with a long service life. Which company is better depends on the preferences of the master. In specialized retail outlets you can see devices for cutting concrete. They are equipped with a wear-resistant diamond chain, which belongs to the category of emergency rescue products. They are not intended for gardening equipment.
The main selection criterion is not the brand and how much it costs, but the wear resistance of the carbide structure and its maintainability. There will be no need to constantly replace the product, provided that there is special equipment for sharpening it, which will significantly extend its service life. The carbide construction is used for sawing hard wood or light building materials.
If you use the device to work with aerated concrete or foam concrete blocks, then even the best models with additional functions will last two or three times less than the established period.
Cross and longitudinal cutting
If the sharpening angle of the links is 25 - 35 degrees, then they are used for transverse cutting of wood. This is the main range of manufactured goods, both Russian and foreign. Products for longitudinal sawing are quite rare. You can eliminate the deficiency by changing the sharpening angle yourself at home, making it standard from 5 to 15 degrees. In this case, the tire is operated without changing the structural elements. If difficulties arise, you can use step-by-step instructions.
When to sharpen
If the teeth are dull, the work will progress slowly. There will be increased vibration, reverse shocks as the headset enters the cut, too many small chips and a distinct smell of burnt wood.
If the tool comes with an installed manual sharpening device, a flat or cylindrical file, then there is no need to remove the element from the tire. Sharpening will occur automatically. If necessary, higher-quality sharpening can be performed in a specialized workshop, in which the action takes place on a stationary sharpening machine. Restoring the teeth's functionality is carried out quickly and efficiently, with a guarantee of the same angle. User reviews boil down to the need to resort to a professional sharpening method.
Lubrication
The tool will function reliably and efficiently if there is timely lubrication. For this purpose, an oil pump is provided, thanks to which oil is supplied to the cutting system through special holes. The oil is evenly distributed thanks to the shanks.
The lubricant is intended, first of all, to reduce friction and overheating of the unit, which allows to increase its operational life and maintain performance at the proper level. The lubrication process must be controlled. It is worth paying attention to the presence of an oil trace on the cutting line. Its absence indicates that the device is overheated, which can lead to dullness or complete failure.
To avoid negative consequences, manufacturers of rated products use an organic base when producing oils. Such new products are more expensive than their analogues, but at the same time the consumption of lubricant is significantly reduced, automatically increasing the service life.
Recoil and vibration
Regardless of the quality of the product, significant vibration and recoil occur under high loads. With light loads, such inconveniences cannot be avoided either, but their power and intensity can be reduced. To reduce vibration you should use:
- shock-absorbing protrusions on connectors and shanks;
- beveled cut stop;
- beveled or high heel of the incisor.
These actions can be carried out with your own hands, without the involvement of outside help. These design features will help minimize the risk of injury due to tool kickback.
How do saws differ in the thickness of the saw chain shank?
The saw set consists of three types of links: working (which directly cuts), connecting (for the bundle) and driving (shanks).
Saw chain device.
The latter are used to fit into the tire and move reliably on it without slipping. There is a counter groove on the bar that accepts the shank. The thickness of the drive link and the width of the groove must match, otherwise the equipment will either dangle or will not fit into the seat.
There are five standard shank thickness sizes:
Size in mm | Size in inches | Description |
1,1 | 0,043” | These are links with the smallest section in thickness. They are only suitable for household saws and light loads. |
1,3 | 0,05” | One of the most popular sizes. Found on household and semi-professional chainsaws. Here is the optimal combination of reliability and chain weight. |
1,5 | 0,058” | Option for semi-professional gasoline saws with increased power. |
1,6 | 0,063” | Standard for professional tools. |
2 | 0,08” | Shanks of this size are quite rare, as they are found only on the most powerful professional-type chainsaws. |
From this sequence it is not difficult to notice a pattern: the thicker the shank, the higher the mass of the headset and the more power a gasoline tool is needed to turn, but the strength and resistance to loads also increase.
Recommendations from specialists for using the unit
In most cases, structural elements do not reach their full potential. This is due to:
- Significant wear on the drive sprocket.
- Ineffective lubrication or its complete absence.
- The saw structure is too tight.
- Use of low-quality oils.
Experts advise purchasing an additional set of devices and changing them as needed. It is worth constantly monitoring the condition of key products. If they are damaged, they must be rejected and replaced with a new one.
The use of low-quality components or those that have completely exhausted their service life is fraught with injury.
Criteria to consider when choosing
In order to optimally select the necessary saw chain for a chainsaw and not overpay, first of all, you need to decide on the frequency of use of the tool. If you use it infrequently for trimming knots and small branches in the garden, you can pay attention to an inexpensive chain. If you are constantly cutting firewood and felling trees, you should purchase an expensive chain from a well-known brand.
In addition, when choosing the required saw chain, it is necessary to take into account other parameters, among which it is worth highlighting:
Which is the best product to buy?
The question arises when there is a need to cut wood, but there is not enough experience and knowledge. Experts recommend following these tips:
- Understand how much work needs to be done and what kind of material you will have to deal with. For cross cutting, a chisel tool is selected, for longitudinal cutting, a chipper tool is used.
- Understand the characteristics of a chainsaw, especially bar length and pitch. There is no point in choosing a specific brand; this indicator is not fundamental.
Where to buy the unit, everyone chooses independently. It is best to visit specialized outlets, talk with a sales manager, decide on the package, hold the tool in your hands, and ask the price. There is an option to order products online in an online store. The main thing is not to encounter counterfeit. This is the advantage of a branded store, where there is a minimal likelihood of purchasing a low-quality Chinese product instead of a branded product.
Semi-skip and skip saw chains
The standard design of a saw chain alternates working links with conventional connecting links, and the elements with teeth differ on the side of the protrusion into right and left.
They are placed sequentially during installation, ensuring uniform cutting across the entire width of the cut. It is generally accepted that 64 driving links should have 32 saw teeth. This results in a 50/50% ratio. Such equipment cuts perfectly and wears out for a very long time.
Working links are more expensive because they are made of durable steel, and some are also soldered. Metal for connecting links is cheaper. To reduce the cost of the saw set, some produce chains with semi-pass and skip. Let's consider what it is and whether the savings are justified.
Half-pass chains
This is a type of saw equipment where an intermediate connecting link is installed between pairs of teeth (the left and right form a pair). As a result, the number of cutting elements is no longer 50%, but 40%.
Half-pass chain.
Chains with skip
In the structure of such chains, an additional “extra” link is installed between each left and right tooth. This further removes the working elements from each other and about 30% of them can remain on one headset.
Chain with pass.
Rationale
Although using 30-40% cutting elements instead of 50% makes the chain cheaper, reducing the teeth makes the saw more aggressive. It twitches more often in your hands and tears the wood, reducing the accuracy of the cut. The scattered arrangement of teeth increases the load on the sprocket, tire and motor, so these components and parts wear out faster.
Hence we conclude: the use of a headset with a pass and a semi-pass provides short-term savings now, but results in increased costs for repairs or the purchase of a new chainsaw in the future.

Difference in the profile height of the cutting teeth of saw chains
The height of the chain profile affects the depth of cut. The higher the teeth, the faster the wood cuts through. But taller teeth contribute to increased vibration. The characteristics of the equipment are indicated in the documentation. Knowing it is necessary for the competent selection of saw accessories and proper sharpening.
Profile height.
There are two common types of profile heights.
Low profile chains (0.635mm or 0.025”)
Found on both professional and household chainsaws. It is small in size allowing for a slow and clean cut. Due to the low height, vibration is significantly lower. Having bought a chain with a high profile, you can convert it to a low one by grinding off the top ridge.
Low profile saw chain.
High profile chains (0.762mm or 0.03”)
High profile chains are developed only for professional gas-powered tools used in forest felling. The enlarged comb of the saw set facilitates quick “biting” of the equipment into the wood, but increases vibration and hand fatigue.
High profile saw chain.
Which profile is better?
It's worth clarifying a little here. Since the cutting speed depends on the chain pitch and profile height, different combinations of these parameters allow you to adjust the performance of the chainsaw and the load on the operator’s hands. The high profile and large 3/4" pitch provide increased load, so are only suitable for professional felling tools where speed is important but frequent breaks will be required.
For construction tasks, cutting firewood and other large-scale work, chains with a long pitch, but a low profile, or with a short pitch, but a higher profile, are used . It is difficult to say unequivocally which option is better, since the type of wood, the power of the chainsaw, and working conditions influence the result. Therefore, the optimal parameters are selected by trial.
