Freud DMARG1140 Hammer Drill Bit 7/16 in Concrete 5 Pack

Product Description

The FREUD DMARG1140 is a carbide-tipped hammer drill bit designed for fast, accurate hole drilling in concrete, masonry, and stone. The bit features a red granite carbide tip produced through a proprietary brazing and hardening process that extends both tip life and overall productivity. A multi-ground grip point tip geometry enables aggressive starts and produces clean holes with consistent accuracy. The impact-resistant shank design provides added stability and durability when used with cordless or corded impact drivers and drill drivers. This SKU ships as a 5-piece set. At 7/16 inches in diameter with a 4-inch cutting length and 6-inch overall length, it covers standard anchor and fastener hole requirements in masonry applications.

This hammer drill bit set is suited for contractors, masons, and trade professionals who regularly drill into poured concrete, block, brick, or natural stone. The 7/16-inch diameter is a common size for anchor bolt installations and structural fastening in residential and light commercial construction. The 6-inch overall length provides enough reach for typical wall and slab penetrations without requiring an extension. Both cordless and corded hammer drills in the SDS-plus or standard keyed chuck configurations are compatible with this bit style depending on shank type.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with hammer drill operation and masonry fastening practices. Confirm the drill is powered off and the chuck is fully secured before inserting or removing the bit. Wear appropriate PPE including eye protection and a dust mask when drilling into concrete or masonry, as required by OSHA standards. Do not use a hammer drill bit in rotary-only mode on masonry, as this will accelerate tip wear and reduce hole accuracy.
