Milwaukee 48-20-9000 Carbide Hammer Drill Bit

Product Description

The Milwaukee 48-20-9000 is a carbide hammer drill bit designed for use with impact drivers in rotary hammer and hammer drill applications. Built from carbide, it delivers the hardness and abrasion resistance needed to bore through concrete, masonry, and similar hard materials. The bit measures 1/8 inch in diameter and 3-1/2 inches in overall length, with a 2-inch working depth. Its SHOCKWAVE Impact Duty construction is engineered to absorb drive torque and reduce bit breakage under the high-impact forces generated by impact drivers and hammer drills. This bit is sold as a single unit and is a practical addition to any masonry drilling kit for field or service work.

This bit is suited for residential and commercial applications where small-diameter holes are needed in concrete, block, brick, or mortar. Common install scenarios include anchoring electrical conduit, mounting HVAC brackets, securing plumbing straps, and similar fastening tasks in masonry substrates. The 1/8-inch diameter makes it appropriate for pilot holes and small anchor placements. It is intended for use by electricians, HVAC technicians, plumbers, and general trade professionals who regularly drill into masonry as part of system installation or service work.
