1/8x3/4 Cobalt Cutoff Blade

It is recommended over the straight-flute for more difficult materials, better surface requirements, and applications with an interruption such as a keyway or cross hole.

Annular cutters cut only that material necessary to produce a quality hole.

Screw machine drills (also know as stub or stubby drills) are manufactured to Aerospace Standard 907.. Ideal for portable or machine drilling.

6 Flute chatterless countersinks are designed to provide more metal removes than the 1,2,3 and 4 flute countersinks.They are also more effective on harder materials.

. The 135 degree split point is self-centering and reduces thrust.
