M-2 high speed steel for strength with black oxide coating for heat and wear resistance in wood, metal or plastic applications; split point ensures a true start and eliminates bit walking.
High speed steel with split point that keeps the drill from skating on hard materials and eliminates the need for a center punch. All 3/16" and larger have 3 flats on the shank so that the chuck gets a better grip on the bit.
Black oxide coated for greater wear resistance; split point drills on contact and prevents walking. Parabolic flute design improves chip ejection in metal and wood drilling applications. Helix is 31 degrees which minimizes the over aggressiveness of a true parabolic flute.
