Hardie Circular Saw Blade, 4-tooth X 6-1/2-in.

The only approved PCD (polycrystalline diamond) tipped HardieBlade generates 5% less respirable dust. PCD triple chip design offers up to 60 times longer cutting life than standard carbide blade. Laser cut thin kerf design requires less power from the saw, causes less user fatigue, and ultimately extends the life of the saw. Anti-vibration design stabilizes the blade and reduces noise while cutting and non-stick Perma-SHIELD permanent coating prevents gumming and corrosion. Covered by Freud's limited lifetime warranty.
