Tooth Profiles
Standard Tooth (0 Degree Rake)
Good balance of cutting speed and surface finish. The most common profile.
Hook Tooth (Positive Rake)

Variable Pitch (Alternating Teeth)
Reduces vibration and handles mixed thicknesses. Produces smoother cuts and less noise.
Selection Rules
Rule 1: Match the Blade Length
Always use the correct blade length for your model. Using the wrong length blade will not fit and can damage the saw. Verify the blade length before ordering.
Rule 2: Match the TPI to the Material Thickness
Use the 3-teeth rule: at least 3 teeth should be in the material at all times.
- Thick material (1/4 to 2 inches): 10 TPI.
- Medium material (1/8 to 1 inch): 14 TPI.
- Thin material (under 1/4 inch): 18 TPI.
- Very thin material (under 1/8 inch): 24 TPI.
- Mixed thicknesses: 10/14 variable pitch.
Rule 3: Match the Blade Material to the Work
- General metal cutting: Bi-metal M42.
- Tough metals (stainless, tool steel): Bi-metal M51.
- Light occasional use: Carbon steel.
Rule 4: Break In New Blades
Run the first 10 to 20 cuts at half feed pressure. This lets the tooth tips wear evenly and prevents chipping.
Rule 5: Use Coolant When Possible
Coolant extends blade life by 50 to 200 percent. For portable saws, use cutting wax or spray coolant.
