NOTICE
DO NOT hammer the tip of a tooth. Due to the
super hardness of the tooth, it is brittle and may
chip from such treatment.

Sharpening Teeth

DO NOT allow any tooth to wear too much before sharpening.
Discard any tooth that has lost more than 1/8" of original bite.
Remove the tooth from the cutting wheel to be sharpened.

Tooth Sharpening Guidelines:

1. Obtain an unused tooth for comparison.
2. Discard any tooth that has lost more than 1/8" of original
bite, whether lost through usage or grinding.
3. Grind off a minimal amount from the end, just enough
to restore the original taper and radius on the end. The
end of the cemented carbide tip and the end of the steel
shank should be flush after grinding.
NOTICE
Sharpening cemented carbide cutting teeth
requires a special process. Have your teeth
sharpened only by a qualified machinist for
obtaining a proper edge and to avoid injury.
