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.

  • 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.
