Circular Saw electric manual: selection subtlety

Circular Saw - effective and functional tool for cutting a variety of materials

Apparatus electric circular handsaw

Each model is hand-circular electric saw works on the same principle. Inside the tool body hidden motor that rotates the cutting blade. The main differences are always in style design - manual or electric. Drive in a manual saw blade is driven manually, as the name implies, but in electric motor costs.

These two types of saws differ not only in size and weight, but the method of torque transfer. The hand-held circular saw with a fixed installation disk is mounted directly on the shaft, in electric models here in torque transmits drive belt.

Also, regardless of the type of blade, there is a special reference platform that allows you to adjust the depth of cut and angle.

A separate type of mini-disc electric hand saws - models that run on battery power. Of course, they can not boast the same power as their counterparts working on the network, but they can be used to carry out the work away from power sources.

Useful advice! During the construction of a country house is convenient to use rechargeable saw. Its light weight and compact size will not let you get tired quickly in the process of cutting materials and the battery is held perfectly without charging more than one hour.

Additional tips for controlling the accuracy of the cutting easier to work with circular saw

Like any other complex tools, circular saws are:

• Household - a relatively small capacity and a set of options, but it is extremely easy to operate and do an excellent job with the saw cut small amounts of materials;
• semi - just a powerful and functional household, but not up to the professional;
• trade - can withstand heavy loads during long-term work, can have a number of useful additional functions that are used in professional development.

If you plan to frequently saw large amounts of building materials, you can not do without a professional model. But in the ordinary repairs on their own would be enough and semi-saws.

How to choose a circular saw

On building tools today's market there are many models of circular handsaws. If you are wondering what kind of hand-held circular saw to choose, there should be understood a number of nuances. First and foremost when choosing a saw, pay attention to the basic characteristics, which will be mentioned below.

Power saws engine - a parameter that directly affects the effectiveness of the instrument. If you want to buy a disc handsaw, on which it will be possible to install the cutting blade of large diameter, then you need a model with a powerful engine. The same behavior has an effect on the cutting depth and power rotation of the disk. A low-power saw can become stuck when cutting very hard wood and bring in the most crucial moment.

Minus any powerful model - its weight. For example, an electric hand circular saw for wood with 1200 W capacity of the engine will weigh approximately 4 kg, and at a power of 2000 W - is 7 kg.

The reference platform allows you to adjust the cutting depth

depth of cut - it depends on the previous option. The more powerful the engine, the greater the drive can be mounted on it. All are 4 size in the depth of the cut saws. The first - a home that is 40-45 mm, the second deepest incision 50-55 mm - used for semi-professional use.

Professional characterized saws cutting depth of 60-70 mm, and the final size of up to 140 mm. the latter type saws are used in industrial production, home to apply them practically impossible. How to choose a circular saw on a tree in the depth of the cut? Compare sizes with their needs. By the way, on some models, is a function of adjusting the cutting depth.

Models with the battery is very useful for working in places where there is no access to electricity

The frequency of rotation of the disk - on this parameter depends on the density of material which may be cut saw. Also, the higher the speed, the cleaner cut.

Useful advice! Many people mistakenly believe that the more the power of the engine, the higher the frequency of the drive speed. In fact, the direct connection between these two parameters is not. Low power saws for cutting chipboard have a large number of turns and cleanly cut the brittle material.

Adjusting the cutting angle - This feature now there are almost all models of electric circular saws for wood. It is mainly used for professional work and not needed for amateur cutting boards or plywood.

Circular Saw electric manual: Advanced

Many modern saws have a number of additional features that allow you to perform more accurate cut and many other things. Below, we consider a number of popular and useful features:

• immersion in the material - this feature allows you to while working with the material to begin his cut not with the edge of the sheet, and from any location;
• connecting a vacuum cleaner - a very useful feature that allows you to blow formed during sawdust. It not only cleans the air in the operating room, but also greatly improves visibility of the material;
• inhibitor - to run a saw mechanism to press two buttons simultaneously. It does not allow the user to run the saw at once, that is, increases the level of safety in the operation;

• soft start - drive begins to rotate smoothly, and not just at full throttle. This extends the life of his work;
• Laser Pointer - if present no need for guide rail for hand-held circular saws. But for this you will need certain skills, as a novice, who took the first circular saw electric hand in hand, make a precise and clean cut will not work;
• Stationary system for removing dust and chips - very practical thing for small amounts of work. For example, in a circular saw Makita 5017 RKB such a container is, which makes it very comfortable to work in confined spaces.

Besides all of the above, it is very important to have hinged protections that cover part of the disc.

Selection of drives for circular Portable circular saws

The main working part of any circular saw - cutting blade. It is with the help of the material being cut. How to choose a disc circular saw with the correct drive? You need to consider with which materials you plan to work. So drive with trapezoidal teeth great for accurate work with many materials, variable teeth used for cutting wood along the grain.

For hard materials we recommend using drives with hardened teeth or carbide-tipped. Price sharpening circular saws with carbide tipped higher than normal, but they last longer and provide a more efficient operation.

Useful advice!External disk size is not as important as the interior. It is the inner diameter of a mounting option. A wrong disk is impossible to fix the saw.

On the number of teeth of the disc depends on the quality and pace of work. To more accurately cut the number of teeth should be greater, but the work in such a case would be slower than a disk with a smaller number of teeth.

Ideally, a good host is always at hand should be several different drives to work most effectively with a variety of materials.

The quality of work is directly dependent on the selected disc for circular saws

Rules for working with circular hand saw

Despite all the security measures and additional accessories, circular saw is a very dangerous tool. In order to minimize the risk of injury at work, some simple rules should be followed. So, you should use circular saws with guide rail for leaf accidentally gone to the side. The part should be fixed as reliable as possible, and to press the chain saw to it stands stronger.
