Richard JHHM-312Click To Copy SDS Max Rotary Hammer Drill Bit, 1" Diameter, 13" Overall Length, 8" Drilling Depth

The Richard JHHM-312 SDS Max rotary hammer drill bit is designed for heavy-duty drilling in concrete, masonry, stone, and reinforced concrete. Featuring an 18mm SDS Max shank (Slotted Drive System), it provides secure fitment and efficient power transfer with compatible rotary hammer drills, enabling both rotational and hammering action. The bit incorporates an aggressive 4-cutter head geometry with carbide tips, typically tungsten carbide, for extended tool life and resistance to wear. Wear mark indicators ensure dimensional accuracy for anchor installations, promoting rounder holes that maximize anchor pull-out values. Rebar chamfers prevent carbide chipping when encountering rebar. A high-volume flute design facilitates rapid dust and debris removal, which helps keep the bit cool and extends its service life. The design also aims to reduce vibration, minimizing stress on the drill motor and operator. The bit measures 1 inch in diameter, has an overall length of 13 inches, and offers an 8-inch drilling depth.
