Closeout – 5-Piece HSS 82° Countersink Bit Set with Aluminum Case – 1/4″, 3/8″, 1/2″, 5/8″, 3/4″
Dial in clean, professional countersinks at a closeout price.
5-piece HSS countersink set (82°) delivers smooth, chatter-free chamfers and deburring across a wide range of materials—steel, aluminum, brass, plastics, and hardwoods. The M2 high-speed steel body holds sharp edges under heat, while the multi-flute geometry keeps cutting pressure steady and finish quality high.
Sizes 1/4″, 3/8″, 1/2″, 5/8″, and 3/4″ cover everyday fab and assembly work—ideal for prepping holes for 82° flat-head screws, breaking edges on drilled holes, and removing burrs before coating or assembly. Each tool seats securely in a drill chuck thanks to the grippy shank, and the foam-lined aluminum case protects your set between jobs.
This is a limited-quantity closeout once they’re gone, they’re gone.
