Richard JHHM-309Click To Copy SDS Max Rotary Hammer Drill Bit, 7/8" x 13" x 8", 4-Cutter

The Richard JHHM-309 SDS Max rotary hammer drill bit features a 7/8-inch diameter, 13-inch overall length, and 8-inch usable length, designed for efficient drilling in concrete, masonry, and reinforced concrete. It incorporates an aggressive 4-cutter carbide head geometry to prevent lock-up in rebar and enhance durability. Integrated wear mark indicators provide better dimensional accuracy for anchor fittings, ensuring holes meet ANSI requirements. Rebar chamfers protect the carbide from chipping, while an active-centering tip produces rounder holes for maximum anchor pull-out values. The bit's high-volume flute design facilitates fast removal of dust and debris, reducing vibration and stress on the drill motor and operator. This professional-grade bit is intended for use with SDS Max rotary hammers.
