Safe work with a circular saw (without a table)
A circular saw is a utilitarian work tool and a useful addition to a DIYer's toolbox. Its most common function is to make straight cuts in pieces of wood. Knowing its parts makes using a circular saw easier.
There are two main types of circular saws: worm gear drive and direct drive.
On a circular saw, you can adjust the angle at which you cut, but the power can vary from one circular saw to another. Most come with a cutting angle of up to 45 degrees.

The best circular saws for home DIY projects
A handheld circular saw is a super versatile and affordable tool for efficiently cutting wood and other materials to size.
With its sharp rotating blade, you can quickly and accurately make curved, linear and straight cuts freehand, ideal for beginners and professionals looking for a lightweight kit that offers great precision and cutting ability.
By looking at the blade diameter measurements, you can determine how deep a cut you can make in your materials. The larger the blade diameter, the deeper the cut.

How to protect yourself from injury:
- Fix adjustable Synthetic rubber headgear cap on the blades, large enough to cover the blades to prevent contact with the blade and access under the machine table.
- Replace the guard before making a test cut after setting up or adjusting the tool.
- Measure the thrust on each tool (at least 300 mm long and serrated to hold the workpiece).
- Use power supplies/automatic feeding devices whenever possible.
- Attach a steel blade to all circular saws.
- Make sure the knives are securely fastened, have a smooth surface, a beveled front edge, and are curved to the shape of a saw blade.
- Use extension tables and stands to cut larger workpieces on the sides.
