Freud DMARG1130 Hammer Drill Bit 3/8 X 12 in Carbide 5 Pack

Product Description

The FREUD DMARG1130 is a carbide-tipped hammer drill bit from the Speed Demon red granite series, designed for fast, accurate drilling in concrete, masonry, and stone. Measuring 3/8 inches in diameter with a 10-inch usable length and 12-inch overall length, this bit is sold in a 5-piece set. The carbide tip is processed through a unique brazing and hardening method that extends service life and maintains productivity in demanding conditions. At 1.25 pounds for the set, it is built for use with both corded and cordless hammer drills and impact drivers. Licensed trades and experienced operators working on structural concrete, block, or stone applications will find this bit suited to their workflow.

This bit set is appropriate for residential and commercial applications where concrete anchoring, masonry penetration, or stone drilling is required. The multi-ground grip point tip promotes aggressive bit starts and produces clean, consistent holes with minimal wandering. The reinforced shank design is rated for use in cordless and corded impact drivers and drill drivers, making it compatible with standard rotary hammer and SDS-adjacent workflows where a 3/8-inch bit fits the chuck. The 5-piece pack supports crews or contractors who go through bits at a regular rate on production drilling tasks.

Installation Notes

Installation is performed by a qualified operator using a compatible hammer drill or impact driver with a 3/8-inch chuck. Confirm the drill is set to hammer mode before beginning core drilling in concrete or masonry. Wear appropriate PPE including eye protection and hearing protection when operating in hammer drill mode. Do not use this bit in a standard drill-only mode on hard concrete or stone, as this will reduce bit life and may damage the shank.
