Milwaukee Tool 48-20-7974 Sds-plus Carbide Drill Bit

Product Description

The MILWAUKEE TOOL 48-20-7974 is a carbide-tipped SDS-Plus rotary hammer drill bit engineered for masonry drilling applications. It features an SDS-Plus shank for positive engagement with compatible rotary hammer tools, delivering efficient hammer and rotary drilling action through concrete, block, brick, and similar masonry materials. The bit has a 1/2-inch cutting diameter, a 10-inch flute length for effective dust and debris evacuation, and a 12-inch overall length to reach depth in demanding applications. Licensed electricians, HVAC mechanics, plumbers, and general contractors routinely use bits of this type when core penetrations or anchor holes are required through structural masonry.

This bit is suited for residential and light commercial construction and service work where SDS-Plus rotary hammer tools are the standard. Typical applications include drilling anchor holes for pipe hangers, conduit straps, equipment mounting brackets, and duct support hardware in concrete or masonry walls and floors. The carbide tip maintains cutting performance across high-volume repetitive drilling tasks common on mechanical and electrical rough-in work.
