Premium High Speed Long Boy Drill Bit – 12″ Long over 1″
12″ Long Boy Drill Bits engineered from M2 High Speed Steel for extra-deep holes and long-reach access. Built with a 12″ overall length and a 9″ cutting depth, these drills excel in beam drilling, thick material penetration, and applications where standard-length drills cannot reach.
Straight shank design on all sizes. Diameters above 1/2″ are cut down to a 1/2″ shank to fit any standard 1/2″ drill chuck. Strong, accurate, and ready for production environments—ideal for drilling steel, hardwood, plastics, fiberglass, and most shop materials.
Perfect for fabricators, installers, millwrights, and anyone needing true long-reach drilling capability.
