Manual Circular Circular Saw – an indispensable tool for work on sawing of materials such as wood, fiberboard, particleboard, plywood, plastic, plasterboard, acrylic glass, aluminum, copper and other nonferrous metals. Circular saw can cut virtually any material, except iron and steel. Circular saw makes it possible to make accurate longitudinal, oblique and transverse cuts. The quality of the cut line and speed circular saw is much higher compared to the jigsaw. But getting cutting line curved shape with the circular saw can not. The device is a circular saw. The motor of a circular saw, using special mechanism (which allows you to smoothly adjust the cutting depth and angle of the disc) is installed on the baseplate.
On more expensive saws, usually installed cast base plate, at a cheap 'punching'. All models of circular saws are equipped with a special mechanism for rip fence, which allows you to quickly and accurately produce parallel cuts of high quality. Circular saws can be conventionally divided into three groups: 1. circular saws or low power (800 W) 2. saws average power (800 – 1200 W) 3. circular saws or high power (over 1200 watts) One of the main technical characteristics of a circular saw, is the depth cut, which depends mainly on the diameter of the saw blade. The larger the diameter of the disk, the more power is required the engine, and more powerful motors have more weight.
In this case you should be able to choose for themselves the optimal ratio of weight, power and price. For most works fit saws with cutting depth of about 55 mm. Circular saws, cutting depth of which, more than 65 mm is classified as a class construction and purchase of such equipment will be justified only if you often have to cut very thick material. More expensive models of circular saws are equipped with control electronics. Electronic Control Module allows you to maintain a constant speed regardless of load and produces a soft-start motor. This feature provides additional convenience at work, as well as prolongs the life of saw blade (in the case congestion or blockages, electronics off the motor). Likewise, there are circular saws with adjustable speed blade. This feature extends the scope circular saws and allows to select the optimum speed for each material. Now, virtually every major manufacturer such as such as Festool, or such as Protool, publishes a special bed for hand-held circular saws, through a bed can easily transform a handsaw in the stationary (in this case, the saw is fixed drive up). In conclusion, let me give you some tips on working with circular saw. In carrying out precision work using fabrics with lots of teeth, this will ensure a smooth and clean drink. Discs with a small number of teeth should be used if you want to large amount of work with high performance. If you plan to work with plastic, keep in mind that the speed of the disc should not exceed 3000 – 4000ob/min, in this case will be very useful function such as regulation speed. Cutting plastic, plasterboard, thin aluminum profiles should be performed using special circular saw blades. Such drives usually have a special grind carbide tips and a large number teeth. Operating a circular saw, use a special bag to collect sawdust dust. For this purpose, so you can use a vacuum cleaner, although this somewhat limits the freedom of movement, but more efficiently remove dust. We hope this overview has helped you understand the technical characteristics of circular saws. But the choice is yours.
