Tackle demanding drilling projects with the GMTOOLS cobalt drill bit set. This 29-piece set features high-speed steel bits with a black and gold oxide finish for enhanced corrosion and wear resistance, making them ideal for stainless steel, cast iron, alloy, wood, and hard plastics.
The 135-degree split point is self-centering and penetrates quickly with less pressure, while the twist design brings metal shavings up and out of the hole. Round straight shanks prevent walking during drilling.
Includes sizes from 1/16 inch to 1/2 inch in 1/64-inch increments. Stored in a durable metal indexed storage case for organization and easy access.
Backed by a 30-day money-back guarantee.
