MADE FROM HIGH-SPEED STEEL AND 5% COBALT: improve much higher heat resistance because of cobalt steel's high red hardness, provide strong durable performance compared to typical hss drill bits.
CAN BE REPEATEDLY SHARPENED AS NEEDED: cobalt drill bit's hardness is uniform throughout the entire material, so that can be repeatedly sharpened without damaging the cutting edge allowing it to drill more than hss drill bits.
APPLICATION: best used for removing damaged bolts and screws, or drilling a pilot hole for a screw extractor.
INCLUDE: 2pcs 5/64 inch, 2pcs 7/64 inch, 1pc 5/32 inch, 1pc 1/4 inch and 1pc 19/64 inch cobalt left hand drill bits with case.

Drill America 1' Reduced Shank Cobalt Drill Bit with 1/2' Shank, DWDCO Series
Cobalt steel tools are similar to high-speed steel, but with more cobalt for improved performance when cutting harder metals such as stainless steel or nickel alloys.
Gold oxide is a thinner oxide surface treatment than black oxide typically used to identify cobalt steel tools.
performance is similar to uncoated tools.
Round shanks allow use with a wide variety of toolholding systems.
When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging.
Cobalt steel tools are similar to high-speed steel, but with more cobalt for improved performance when cutting harder metals such as stainless steel or nickel alloys.
Uncoated tools feature just the base substrate without any additional treatment or coatings and are suitable for a wide range of applications.
