No matter what wood-boring project you face, IRWIN makes a drill bit to do the job better. Whether the job AT hand requires quick, clean holes or precise finish work, there's an IRWIN bit for it. Our mark of quality is stamped on the shank of our full range of bits for every application and every need.
Patented micro-groove cutting edge and spurs produce a smoother hole finish
Double spur design scribes the hole before the chips are made, producing a cleaner hole and reducing vibration
Shorter bit length gets into confined spaces (between studs) where standard lengths will not fit
All bits have a 1/4 In. hex shank that fits all drills and 1/4 In. quick change adapters
