TWOFERS 100/120
Regular Mesh Grit Bits
During the manufacturing process, bit samples are randomly tested
for quality control. Bits are tested by grinding steel with a hardness rating of HRC 55-58.
Each bit batch tested must endure 10 hours of continuous work with a
constant lateral pressure of ~10 lbs/sq.in. driving the test bar
into the bit abrasive for the lot to pass inspection.
These do not fit the Power Max Grinder or the Glastar All-Star
