Freud DMARG1020 Hammer Drill Bit Carbide Tipped Masonry

Product Description

The FREUD DMARG1020 is a carbide-tipped hammer drill bit engineered for fast, accurate drilling in concrete, masonry, and stone. Part of the Speed Demon red granite series, this bit features a unique brazing and hardening process that extends carbide tip life and maintains productivity through high-cycle use. The multi-ground grip point tip geometry provides aggressive bit starts and produces clean holes with minimal wandering. At 5/32 inches in diameter with a 3-inch working length and 6-inch overall length, it fits standard rotary hammer and hammer drill chucks. Licensed contractors and trade professionals working in concrete and masonry applications will find this bit built for both cordless and corded tools.

This bit is suited for residential and commercial construction tasks requiring reliable penetration into concrete, block, brick, and natural stone. Typical applications include anchor hole drilling, conduit rough-in, plumbing penetrations, and mechanical attachment points. The impact-strong shank design maintains stability and resists shank deformation during extended use in both corded hammer drills and cordless impact-rated drill drivers. The 5/32-inch diameter is a commonly specified size for light-duty anchoring and fastener pilot holes in masonry substrates. Sold in a package quantity of 5, this part is practical for stocking service vehicles or shop inventories.
