Aanraku TWOFERS Diamond abrasive bonding is double plated for strength, dependability and long life.
You will not find a more Reasonably Priced, Higher Quality Grinder Bit on the market today.
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, Studio Pro and possibly other
DiamondTech Grinders. They also do not work on the Glastar All-Star.
