All about Interskol circular saws

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 subject to this - manual models are in no way inferior in power to their stationary counterparts, except in the diameter of the cutting blade.

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.

First, let's consider the advantages of Interskol circular saws.

The latest model presented by the company Interskol - plunge-cut circular saw PP-165 / 1300EM.

This model is equipped with an efficient motor to ensure smooth operation and a good cooling system, a soft start system that reduces the load on the motor, and convenient speed control to maintain the required power when processing difficult materials. The comfortable and ergonomic design provides a comfortable grip while working and reduces vibrations transmitted to the operator. A wide range of disc blades is available for this model to work with virtually any material. And also this model is equipped with a special sole, which is adapted to the change in the angle of the tire attachment to handle uneven surfaces and jewelry accuracy of cuts. Various tires are optionally available to change the size and depth of the cut.

Technical characteristics of models:

• engine power 1300 W;
• spindle speed 2000-5000 rpm;
• cutting depth (90? / 45?) 55/38 mm;

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 not 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. The 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 there are glued strips of soft material for better gliding 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.

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

• Specifications - 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 at the dacha - 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 - quite an 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 a sales consultant.

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 sufficiently tightened, 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 sparks or a burning smell suddenly 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 in a set with a 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.
