Saw Blade Design - Illustration and description of carbide tip circular saw blade design elements
Back Angle:Clearance angle at top of blade. Affects shoulder strength and changes with blade type.
Copper Plug:Press‐fit into saw plate to assist with vibration dampening and noise reduction.
Expansion Slot:Reduces vibration and noise. Allows expansion and contraction caused by heating.
Face:Flat plane of each tip that is parallel with hook angle.
Gullet:Area / volume between shoulder and next tip into which material being cut gathers and is ejected.
Bolt Hole Circle:The common diameter for all pinholes on the saw blade.
Bore:Saw blades are mounted to the cutting machine. Also known as the arbor hole.
Hook Angle:Angle formed between tooth face and a radial line from center of bore.
Forward leaning = Positive
Backward leaning = Negative
Alternate Face Bevel:Provide angle bevel on tooth face for ATB grind only.
Kerf:Carbide tip width measured at widest point.
Radial Side Clearance (Top‐Btm):Angle created by precision grinding to prevent side of tip from contacting material being
cut and causing melting or burning.
Tangential Clearance (Front‐Back):Relief from front of tip to back of tip to provide clearance during cutting to prevent
melting or burning.
Top Bevel Angle:Created by precision grinding the top of each tip. A steeper (larger) angle provides a sharper tooth, but
one which becomes dull more quickly.
