Irwin HSS Drill Bit 3/8" x 12"

Engineered for professionals and DIY enthusiasts alike, the Irwin HSS (High Speed Steel) 3/8" × 12" drill bit delivers exceptional performance when tackling metals, wood, plastics, fiberglass and stainless steel. Its extended length reaches deep or hard-to-access areas, while the precision 135° split point starts on contact and virtually eliminates walking. A durable black oxide finish resists corrosion and wear, and the parabolic flute design evacuates chips quickly for smoother drilling and longer tool life.

Whether you’re running cable through studs, fabricating metal assemblies or working on general-purpose projects, this bit maintains concentricity in the chuck and stays sharper, longer—drilling straight, clean holes every time.
