BLADE TERMINOLOGY

1. BLADE BACK – The body of the blade not including tooth portion.
2. THICKNESS – The dimension from side to side on the blade.
3. WIDTH – The nominal dimension of a saw blade as measured from the tip of the tooth to the back of the band.
4. SET – The bending of teeth to right or left to allow clearance of the back of the blade through the cut. KERF – Amount of material removed by the cut of the blade.
5. TOOTH PITCH – The distance from the tip of one tooth to the tip of the next tooth.
6. TPI – The number of teeth per inch as measured from gullet to gullet.
7. GULLET – The curved area at the base of the tooth. The tooth tip to the bottom of the gullet is the gullet depth.

8. TOOTH FACE – The surface of the tooth on which the chip is formed.
9. TOOTH RAKE ANGLE – The angle of the tooth face measured with respect to a line perpendicular to the cutting direction of the saw

TOOTH FORMS & TOOTH SET

VARIABLE

• Standard tooth forms
• Variable tooth spacing
• Varying gullet depth

VARIABLE POSITIVE

• Smooth cutting
• Reduces noise
• Cuts efficiently
• Enhances blade life

VARIABLE

• Wide gullets
• Evenly spaced teeth
• Good cutting performance on non-metallic applications (wood, plastic, cork and composition material)

STANDARD

• Deep gullets
• Evenly spaced teeth
• General purpose design for wide range of applications

HOOK

• Wide gullets
• Evenly spaced teeth
• Positive rake angle
• Good cutting performance on metals which form discontinuous chips (cast iron) and nonmetallic applications (wood, plastic, cork and composition material)
