Cobalt M35 Steel Straight Shank Drill Bit - 5/16", High Speed Jobber Bit

High Speed Jobber Bits

M-35, 5% cobalt, and extra thick drill core for optimum life and durability in hardened steel, super alloys, titanium and stainless steel applications. Split point minimizes bit walk. All sizes 3/16" and larger have three flats on the shank for a better grip on chuck. 135° Split point eliminates the need for a center punch and keeps the drill from skating on hard materials.
