Freud DMARG1150 Hammer Drill Bit 1/2x4x6 Carbide 5 Pack

Product Description

The FREUD DMARG1150 is a carbide-tipped hammer drill bit designed for fast, accurate drilling in concrete, masonry, and stone. Measuring 1/2 inch in diameter with a 4-inch usable length and 6-inch overall length, this bit uses a red granite carbide tip that has been optimized through a specialized brazing and hardening process to extend service life and maintain cutting speed under heavy use. The multi-ground grip point tip geometry enables aggressive starts and produces clean holes with minimal wandering. Sold as a 5-pack, this set is suited for professional contractors, masons, and trade technicians who demand consistent performance across high-volume drilling tasks.

This hammer drill bit is built for use in residential and commercial applications involving concrete slabs, block walls, brick, and natural stone. The shank is impact-rated for increased stability and durability, making it compatible with both cordless and corded hammer drills as well as impact drivers. It is a practical choice for anchoring, roughing in, and general fastening work in masonry substrates where hole quality and bit longevity are critical to job efficiency.
