Selecting the Right Tooth Pitch for Metal Cutting Applications
TPI means teeth per inch. Choosing the correct TPI is important because it affects cutting speed, chip removal, blade life and surface finish. As a general rule, thicker materials require coarser tooth pitch, while thinner materials require finer tooth pitch.
Material Thickness
Thicker solid materials usually require fewer teeth per inch for better chip clearance, while thin-wall materials require more teeth per inch to reduce tooth damage.
Material Type
Different metals such as mild steel, stainless steel, aluminium and alloy steel may require different pitch selection based on hardness and cutting condition.
Cutting Performance
Correct TPI selection helps balance cutting speed, blade life, cutting accuracy and surface finish for stable production performance.
Blade TPI Selection Reference Charts
Use these visual reference charts as a quick guide when selecting the appropriate tooth pitch based on solid material size, structural profile thickness and cutting application.
Tooth Pitch for Solid Material
Recommended blade tooth pitch based on solid material diameter or section size.
Tooth Pitch for Structural Materials

Important Selection Tip
For best results, at least 3 teeth should be in contact with the workpiece during cutting. Too few teeth can cause tooth stripping, while too many teeth can reduce chip clearance and increase heat buildup.
