45/64 inch Cobalt Stub Drill Bit

This cobalt stub drill bit meets Aerospace Standard 907 for heavy-duty use. It is designed for professional mechanics and industrial maintenance teams who need short, rigid tooling in tight spindle clearances.

Check shank compatibility and material hardness

Verify that your drill chuck or collet accepts the 45/64 inch shank before ordering. The 135 degree split point is optimised for iron and steel families; softer or abrasive materials may require a different point geometry.

Sustained drilling in steel

The 135 degree split point reduces thrust and self-centres during extended cuts in tough alloys. Short flute length limits heat buildup and chip packing, keeping the bit stable through repeated holes without wandering.
