220Grit - Twofers From Aanraku
Includes two bits.
Make a small groove in the side of glass
for attaching wire, etc...
Like all Inland bits, the brass cores are
manufactured on "Swiss precision" machinery for consistent and accurate
tolerances.
Bits are measured for true before the diamond is applied, so the bits spin
properly on the motor shaft.
IMPORTANT! Always use safety glasses when
grinding.
