A circular saw is a powerful tool that’s ideal for making straight cuts in a variety of types of timber.
Like any powertool, circular saws can be dangerous, so when you’re using one, make sure you’re wearing the appropriate safety gear, including eye protection, a respirator and hearing protection, as well as sturdy closed-toe shoes.
Check out these tips to make circular saws easier to use.
1. To make sure cuts are straight, use a cutting guide. To position a cutting guide, first measure the offset of your saw. In this case it’s 40mm. Mark the cutting line on the timber, and position the guide 40mm from the line.
2. When starting a cut, nick the timber first with the blade to check that it’s aligned properly, then finish the cut.
3. When cutting panels, make sure they’re supported across the panel to avoid the saw binding. Position offcuts evenly underneath the timber on either side of the cutting line.
4. To avoid splintering, adjust the depth of the saw blade so it’s only half a tooth below the surface of the timber.
5. Circular saws cut on the upstroke, so ensure the good side of the timber is facing down.
6. To avoid damaging the surface of coated materials like formply or laminate, apply masking tape across the surface, then mark the cutting line and make the cut.
7. To prevent binding and kickback, don’t clamp or support the waste piece of timber, just allow it to fall freely.
