Closeout – 5-Pc HSS 82° Countersink Bit Set (1/4″–3/4″) with Case

Description

5-piece HSS countersink set delivers clean, repeatable 82° chamfers for flat-head fasteners and edge-breaks after drilling. The M2 high-speed steel construction handles common fabrication materials—mild steel, aluminum, brass, plastics, hardwoods—while the multi-flute design helps keep vibration down and surface finish up.

Sizes 1/4″, 3/8″, 1/2″, 5/8″, 3/4″ cover day-to-day tasks from fence hardware installs to plate fabrication and general construction. Drop them in a drill press for production work or run them in a cordless for quick deburring. Packed in a foam-fit aluminum case so the set stays complete between jobs.
