Drill America 15/16" x 18" HSS Extra Long Drill Bit - 1/2" Shank

The Drill America 15/16" x 18" HSS Extra Long Drill Bit gives you the reach you need for deep-hole drilling without sacrificing strength. Made from high-speed steel, the bit combines hardness and toughness, delivering reliable wear resistance for everyday tasks in the iron and steel families. A black oxide treatment adds lubricity and creates tiny pockets that hold coolant right at the cutting edge, helping to keep temperatures low and extending tool life. The 1/2" round shank fits most standard chuck systems, so you can swap bits quickly and keep the job moving. Designed with a standard 118 degrees point and right-hand spiral flutes, the bit efficiently evacuates chips when run counterclockwise, reducing heat buildup and producing cleaner holes. Whether you're working on structural steel, pipe, or heavy-duty hardware, this extra-long drill bit provides the depth, durability, and performance you expect from a professional-grade tool.
