How to use a circular saw

Posted by lara linda on October 24th, 2019

Learn the basic types of circular saws and their uses. They vary in blade composition, the number of teeth (cutting surfaces), die size (the width of the material removed by the blade) and the quality of the blade. Best miter saw 

Some of these saws may have a high-speed steel blade at the time of purchase.

Tungsten tipped blades are much more durable, especially when cutting hardwoods. In addition, laminated wood and composite materials are wear-resistant for the sheets, therefore tungsten sheets are more convenient.

Blades with few teeth (eg 28) and with a smaller cutting surface are ideal for tearing along the grain of the wood. They make a fast and rough cut. They are cheap and easy to sharpen, due to their small number of teeth.

Blades with a larger number of teeth (eg 40) are designed for cross-cutting work. They make a sharper cut in most cases. Best miter saw reviews 

Abrasive sheets are made of silicon carbide or other abrasive materials and are joined by a resin material or some other synthetic material. They are used to cut concrete or metal. They tend to wear out quickly, but for small projects, they are ideal because of their low cost and because they make very fast cuts.

Diamond edge sheets. These sheets are made of special metal alloys with diamond inlays at their edges (end of the blade diameter), and are designed to cut hard concrete, composite cement materials, and building materials such as brick and block.

Tempered Alloy Sheets These sheets have teeth made of tempered carbon steel, which are very thin (small and compact) and are used to cut metal sheets such as galvanized sheets, aluminum, copper, or brass pipe.

Given type sheets. These are sheets that can be adjusted to make different die cuts (width of material removed as the cutting blade passes). These sheets are ideal for cutting dice and butt joints, which are used to tie the wood.

Leaves to trim and style. These sheets have fine teeth, to make fine and precise cuts on finished materials such as moldings and shelves.

Support the material to be cut so that the cutting blade does not come into contact with any material that is below the cutting step. For example, you should not place a cutting board on the floor or on concrete. Use a cutting table or easel to do the job.

Mark the wood that you are going to cut to size, with a measuring tape, step meter, or with a ruler, and then use a square (steel, triangular or angle) to mark the step that the blade will travel along with the cut.

Adjust the saw to the desired depth of cut. Make sure that the saw blade is not exposed more than necessary when making the cut. So to make a 40 mm thick cut, adjust the blade to a depth of 45 mm or 50 mm. This helps the saw not to get stuck and prevents it from turning backward.
