Freud DMARG1030 Hammer Drill Bit 3/16x4x6 in 5-pack

Product Description

The FREUD DMARG1030 is a carbide-tipped hammer drill bit from the Speed Demon red granite series, designed for fast, accurate hole drilling in concrete, masonry, and stone. Measuring 3/16 inches in diameter with a 4-inch working length and 6-inch overall length, this bit is built for both cordless and corded hammer drills and impact drivers. A unique brazing and hardening process is applied to the carbide tip to extend service life and maintain drilling speed under heavy use. This package contains 5 bits, making it a practical stocking choice for HVAC, plumbing, and electrical trades that regularly anchor into masonry substrates.

The DMARG1030 is suited for residential and light commercial applications where 3/16-inch anchor holes are required in concrete block, poured concrete, brick, or natural stone. Typical installation scenarios include mounting electrical conduit hangers, plumbing supports, HVAC equipment bases, and mechanical equipment brackets to masonry walls or concrete slabs. The 6-inch overall length provides enough clearance for standard chuck depths while keeping the bit rigid under hammer action.

Installation Notes

Hammer drill bits of this type are installed by licensed electricians, plumbers, HVAC technicians, and general mechanical contractors when anchoring to masonry or concrete. Confirm the drill tool is set to hammer mode before use and wear appropriate eye and respiratory protection, as concrete drilling generates fine silica dust. Do not use this bit in a standard rotary-only drill without hammer action, as doing so will reduce performance and shorten tip life. Verify anchor hole diameter requirements against the fastener or anchor manufacturer specifications before drilling.
