Determining If a Change of the
Diamond Sharpening Wheel Is Required
Reverse the grinding wheel before you replace it. The grinding
wheel supplied with the Drill Doctor
long and trouble free service, with an average of more than 200
sharpenings.
The diamond wheel may need to be changed if:
1. Sharpened drill bits burn or turn blue no matter how fast
or slow you rotate the chuck.
2. When touching the sharpening wheel (with the machine
disconnected), the lower portion feels too smooth
(nonabrasive).
3. When sharpening the drill bit, it takes too many half-
rotations to sharpen.
If you sharpen only 3/32" to 1/2" bits, you can double the life of
the diamond wheel by reversing it. Bits larger than 1/2" use the
entire diamond wheel surface so reversing will not be an
advantage. Contact the store or dealer where you purchased
the Drill Doctor
sharpening wheel.
