Freud DMARG1170 Hammer Drill Bit 5/8x4x6 Concrete Masonry

Product Description

The FREUD DMARG1170 is a carbide-tipped hammer drill bit engineered for fast, accurate drilling in concrete, masonry, and stone. The Speed Demon red granite carbide tip is optimized through a specialized brazing and hardening process that extends tip life and maintains drilling productivity over repeated use. The multi-ground grip point tip design enables aggressive starts and produces clean, fast holes with minimal walking. Built impact-strong for increased shank stability and durability, this bit performs reliably in both cordless and corded impact drivers and hammer drills. Licensed contractors, masonry tradespeople, and experienced installers are the primary users of this tool.

This bit is suited for residential and commercial applications where drilling into concrete, block, brick, or natural stone is required. Common install scenarios include anchor setting, conduit penetrations, pipe sleeve installations, and structural fastening in concrete substrates. The 5/8 inch diameter, 4 inch flute length, and 6 inch overall length make it a practical choice for through-penetrations and deeper anchor holes where a standard-length bit falls short. The bit ships in a package quantity of 5, making it well suited for job-site stocking.
