1/16″ Cobalt Drill Bit. .0625 decimal equivalent 7/8″ flute length 1 7/8″ overall length. Cobalt drills feature a 135 degree split point for instant penetration without a center punch. These drills are made from a special alloy of M42 steel containing 8% cobalt. The extra thick drill core adds further rigidity and strength.

135-degree point begins drilling immediately, minimizing bit walk
Tough metal drilling, including heavy-duty abrasive alloy metal drilling on hardened steel
5-1/2 Cobalt Alloy Steel for higher heat and abrasion resistance
Heavy-duty with construction for strength and durability
