Drill America 29-Piece Assorted Cobalt Twist Drill Bit Set

Drill America DWD29J-CO-PC Cobalt Drill Bit Set contains 29 jobber (standard) length cobalt drill bits from 1/16 in. to 1/2 in. (1/64 in. increments). Drill America cobalt drills are manufactured to National Aerospace standard 907. These drill bits display high red hardness, permitting speeds up to 30% greater than with conventional M2 high speed steel, and are especially effective in drilling tough, high tensile strength materials like stainless steel, Inconel, and titanium. The 135° split point is self-centering and reduces thrust. The Drill America DWD29J-CO-PC Cobalt Drill Bit Set comes in a unique round drill index that combines form and function into 1 beautifully designed, easy to carry drill set. The shatter proof, water resistant case fits easily, anywhere you need it. Effortlessly grip the set in 1 hand as you would a travel coffee mug, leave it in the cup holder of your truck while on the way to your job or hang it on your belt when all hands are on deck. Sizes included in the set: 1/16 in., 5/64 in., 3/32 in., 7/64 in., 1/8 in., 9/64 in., 5/32 in., 11/64 in., 3/16 in., 13/64 in., 7/32 in., 15/64 in., 1/4 in., 17/64 in., 9/32 in., 19/64 in., 5/16 in., 21/64 in., 11/32 in., 23/64 in., 3/8 in., 25/64 in., 13/32 in., 27/64 in., 7/16 in., 29/64 in., 15/32 in., 31/64 in. and 1/2 in.
