Milwaukee Electric Tool Corp 48-20-9054 Carbide Hammer Drill Bit

Product Description

The Milwaukee Electric Tool Corp 48-20-9054 is a carbide-tipped hammer drill bit engineered for high-impact masonry and concrete drilling applications. Measuring 1 inch in diameter with a 10-inch working length and 12-inch overall length, this bit is built for rotary hammer and hammer drill use in demanding trade environments. The carbide tip is designed to resist heat and wear under repeated impact, maintaining a clean bore through block, brick, poured concrete, and similar substrates. Licensed electricians, plumbers, HVAC installers, and general contractors use bits in this class when penetrating structural masonry for conduit, pipe, or mechanical system rough-in work.

This hammer drill bit is suited for residential and commercial construction and mechanical rough-in applications where large-diameter holes must be driven through concrete or masonry. Typical use cases include core penetrations for conduit runs, pipe sleeves, and anchor installations in block walls or concrete slabs. The 1-inch diameter is a common size for single-trade penetrations and anchor bolt holes. This package contains 3 bits per unit of measure, providing job-site quantity for multi-hole layouts or replacement inventory.

Key Features

• Carbide tip engineered for sustained impact resistance in concrete and masonry
• 1-inch diameter cutting face for standard trade penetration sizing
• 10-inch working length allows drilling through thick walls and slabs
• 12-inch overall length provides clearance and reach in tight framing conditions
• Packaged in quantities of 3 for multi-hole or multi-trade job-site use

Compatibility

Designed as an OEM-style replacement and standard consumable for rotary hammer drills and hammer drills accepting a 1-inch diameter shank configuration compatible with this bit series.

Installation Notes

Installation of this bit should be performed by a qualified tradesperson familiar with hammer drill operation and masonry penetration procedures. Always confirm the drill chuck or SDS chuck is fully secured before operation, and wear appropriate eye and hearing protection. When drilling through fire-rated assemblies, consult applicable fire-stop code requirements before creating penetrations. Do not use in standard rotary-only drill mode, as impact operation is required for effective carbide tip performance.
