• TPI: Teeth per inch:
The lower the TPI, the faster the blade will cut. The higher
the TPI, the cleaner the blade will cut.
• Tilt angle:
The tilt angle is the angle at which the blade cuts into the material.
A higher tilt degree produces a faster, more aggressive cut. Tilt
angle is optimized based on application for best life to speed ratio.
• Gullet:
The space between each tooth that collects and clears out the
material being cut. The deeper the gullet, the more efficiently the
chips are cleared.
• Blade shapes:
Taper blade bodies are designed for plunge cutting, curve cuts and
easier starts in tough to reach applications. Non-taper bodies offer
more stability and straighter cuts.
• Settings:
Blade tooth settings vary from one blade to another to optimize
cutting efficiency by material applications.
• Body thickness:
Thinner blades offer faster cutting and flexibility for flush cutting.
Thick kerfs offer straighter and more stable cutting.
• Reinforced tooth:
A wide tooth base with a smaller gullet results in a stronger
tooth design.
