Product Description

The FREUD DMARG1160 is a carbide-tipped hammer drill bit designed for drilling into concrete, masonry, and stone. Measuring 1/2 inch in diameter with a 10-inch working length and 12-inch overall length, this bit is part of the Speed Demon red granite series engineered for fast, accurate hole production. The carbide tip is optimized through a specialized brazing and hardening process that extends service life and maintains drilling productivity across demanding applications. This set includes 5 bits and is suited for installation by plumbers, electricians, HVAC technicians, and general contractors who regularly drill into masonry substrates.

This bit is used in residential and commercial applications where penetrations through concrete slabs, block walls, and stone substrates are required. Common scenarios include anchor hole drilling, conduit penetrations, pipe sleeve installations, and mechanical fastener placement. The multi-ground grip point tip supports aggressive starts that minimize bit walking on hard surfaces. The reinforced shank construction is compatible with both cordless and corded hammer drills as well as impact drivers, making it practical across a range of jobsite power tools.
