When choosing a diamond blade, the type of blade is important. What’s also important are the blade thickness and diamond grit.
How blade thickness affects performance
Speed and dust
- Thinner blades (1/16”) trim slightly faster and create less dust.
- Thicker blades (3/32”+) trim slightly slower and create slightly more dust.
Straight vs curved cuts
- With small diameter blades (1-1/2” to 4”):
- making straight cuts is faster with a 1/16” blade
- making radius/curved cuts, it’s advisable to use a thicker blade (3/32”)
- Larger blade diameters 5” to 16” need to be thicker to retain their rigidity to avoid warping.
