At the moment, a circular saw is an indispensable tool in everyday life, and in professional wood processing it is the main equipment. Now on the market there are a huge number of different circular saws from all manufacturers of power tools. Circular saws are divided into two main types - stationary circular saws mounted on a fixed bed and hand-held models. This article will focus on portable hand tools. Surprisingly, but contrary to the general tendency to reduce power with a compact device, circular saws are not susceptible to this - hand-held models are in no way inferior in power to their stationary counterparts, except in the diameter of the cutting disc.

Today our eyes will be turned to the products of the Interskol company . This is a domestic manufacturer whose tools are characterized by excellent quality and affordable prices. Due to this, the company's niche in the construction tools market is constantly growing and is being replenished with new models.

Interskol circular electric saws are presented in a wide range of models with a large price range.

A circular saw manufactured by Interskol is designed for longitudinal and cross-cutting of wood, wood materials (plywood, chipboard, MDF, OSB), various composite materials, as well as plastic and some non-ferrous metals. To cut non-ferrous metal (aluminum profile, for example), you need a special carbide disc, which can be easily purchased at a hardware store.

Advantages and disadvantages

First, let's consider the advantages of Interskol circular saws. Circular saws are an indispensable tool in the woodworking industry, construction, furniture production, window and door manufacturing. Saws "Interskol" are an excellent domestic analogue of foreign models, they perfectly cope with the tasks assigned to them.

Parts and accessories

There are not so many accessories for circular saws, but their usefulness cannot be overestimated - this is a guide rail, rubber pads, an eccentric for adjusting the exact cutting length. It makes no sense to talk about the last two in detail, but we will tell you more about the bus.

Every experienced carpenter knows: no matter how hard you try, it is almost impossible to get a perfectly straight cut, the saw constantly strives to deviate from the marked trajectory due to vibrations. And then a banal device called a guide rail comes to the rescue. It allows the hand-held circular saw to follow the intended path without deviations. For stationary circular saws, tires are made by attaching a pair of clamps, but in the case of a manual model, this is impossible.

When using a special bar, you only need to attach it with the help of special fasteners to the saw blade frame, and you can start working. The distance from the disc blade to the tire edge is no more than 20 mm. Unlike the rule, you do not need to monitor the possible movement or force of pressing the rule against the material, because fragile materials can be squeezed or broken - with a tire, you only need to smoothly guide the saw along the cut line. Branded tires are designed exactly according to the typical dimensions of a circular saw, so the edge of the tire practically touches the cutting disc, on special tires, strips of soft material are glued to improve glide on the material.

There is a huge number of accessories for circular saws on the market - bearings, stators, rotors, motor armature. These elements of the circular saw are most susceptible to damage and wear, you can try to replace the broken part yourself, but do not forget that the warranty for the tool in this case will be nullified.

We recommend that you use the warranty repair services at specialized service centers. But even if the warranty period for your tool expires, top-class specialists will always help you in service, and you will be sure that your tool will be repaired in accordance with all the rules and recommendations from the manufacturer.

Subtleties of choice

There are several factors to consider when choosing a hand-held circular saw.

Characteristics - this information is available to the buyer when choosing. This is the angle of inclination of the cut, the spindle speed, engine power, the presence of various types of protections and functions: soft start, speed control, the ability to connect additional equipment, a laser pointer.

• Appointment - for home use, semi-professional or professional tool. There is absolutely no need to buy a professional tool, if you need to cut several MDF or chipboard canvases in the country - a saw of the initial price segment is perfect for you.
• Price range . A lower price for a particular model of a tool does not mean at all that it is worse made. Now there are a huge number of manufacturers on the construction tools market, competition forces them to make high-quality equipment at affordable prices. Often, the entry-level price segment means a tool intended for use in everyday life, it has a more modest set of functions and less power. A professional tool costs much more because of its power, productivity, many additional functions, reinforced power units, many protections and is designed for continuous use.

• Processing material - a rather important aspect, because for processing wood of various thicknesses, you will need to take into account the capabilities of the tool. It is the same with non-ferrous metals and composite materials: does this model have a special disc blade for processing this or that material.
• Maintainability of the tool . Some manufacturers make their products, so to speak, "disposable". Always compare models not only in terms of technical parameters, but also read reviews about them, consult with a sales consultant.

User manual

Complete with hand-held circular saws, a complete instruction manual is supplied. Let's describe the basic rules.

Before turning on the saw, it is always necessary to check the integrity of the power cord for damage and kinks, whether the nut that secures the saw blade is tightened enough, the correct operation of the protective cover mechanism, if your model has it movable.

When turning on at idle, listen to the engine for any extraneous sounds and crackling, indicating a malfunction in the engine, and if suddenly sparks or a burning smell appear, immediately unplug the saw.

If your tool is not in the professional segment, give it occasional rest while working, be sure to use a suitable disc blade for the material.

When working with a hand-held circular saw, wear protective goggles and a special gown to protect you from flying sawdust or sparks (when cutting metal), try to keep the nozzle from which the sawdust is flying, not in your direction, or connect a special vacuum cleaner.

Replacing the disc blade:

• the operation is carried out using a key that is included with the saw;
• clamp the locking spindle to fix the saw;
• after that, you can begin to twist the nut that secures the disk;
• remove the nut and flange, then you can remove the disc;
• be sure to clean the pulley, upper and lower protection from sawdust and dust accumulated there;
• after that, you can put a new blade on the pulley;
• start the assembly procedure in reverse order.

Never start the saw unless you are sure that the fixing bolt is tight enough.

Be sure not to be lazy to read the instruction manual for your model, there will be more and more detailed descriptions.
