Prepare for the Material
The first and important thing is to prepare the material. And for that, you will need clamps, a marker/pencil, and a stable work table to put the piece on. Make a straight line on the metal/plywood using a pencil and rulers.
You can also use the markings on the work table to make a straight cut. Many worktables comprise laser light that is extremely helpful while making simple, straight cuts on both, small and larger boards.
Attach the right blade
One blade cannot cut all types of materials. Therefore, it is important to attach the right saw blade for cutting metal/plywood, or any other material. Even for wood, you need to consider the right cutting blade as softwood cuts easily than hardwood. Below is a quick reference guide for choosing the right circular saw blade to cut different materials.
- Plywood: 24-T blade
- Solidwood(Crosscutting): In between 40T to 80T ATB
- MDF/Particleboard/Melamine: In between 40T to 80T ATB or TCG blade
- Plastic sheet/PVC pipe/Non-ferrous metals: 80-tooth TCG blade
Set cutting depth
After marking up the material and fixing the right blade, it’s time to set the cutting depth. The depth of the blade should be just a quarter more than the actual cutting depth. This ensures smooth and precise cutting of the material without damaging the work table. Do not set the depth too low. This might result in uneven cutting as well as can prove to be dangerous.

For professionals, it is easy to follow the cut mark line. In many cases, they don’t even need to mark the material. They simply follow the bright red laser line on the board that gives optimum cutting accuracy.
While straight cutting is easy with Kreg- rip-cut guide, you’ll find it difficult to cross-cut the material with the tool. So it is better to use speed square or combination square for accurate straight cuts.
