Description:
The drill bit complies with National Aerospace Standards.

The drill bits are made from M2 or M7 tool steel with self-centering, 135 degree, P3 split points and a Rockwell C scale hardness of 63.5 to 66. They are manufactured as right-hand tools with 5/16" hex wrench flats and 1/4-28 UNF-2A external threads. TightFit® threaded shank drill bits are concentric, self-tightening, non-slipping, long life tools designed for work in limited space situations. The decimal size of a #30 is 0.1285".

TightFit® threaded shank drill bits WORK EQUALLY WELL IN METAL, WOOD OR PLASTIC.
