Milwaukee Tool 48-20-7932 Sds-plus Carbide Drill Bit

Product Description

The MILWAUKEE TOOL 48-20-7932 is a carbide-tipped SDS-Plus rotary hammer drill bit engineered for masonry drilling applications. With a 1/4-inch cutting diameter and an 8-inch overall length, this bit delivers the reach and durability needed when drilling into concrete, block, brick, and similar hard substrates. The SDS-Plus shank provides positive chuck engagement and efficient hammering energy transfer, reducing bit slippage and operator fatigue during extended use. Licensed electricians, HVAC techs, plumbers, and general contractors routinely reach for this bit when setting anchors or routing penetrations through structural masonry.

This bit is suited for residential and light commercial masonry work where consistent, clean-diameter holes are required. Typical applications include drilling anchor bolt holes, conduit penetrations, pipe sleeves, and equipment mounting points through poured concrete or CMU block. The 6-inch flute length provides effective chip and dust evacuation, keeping the bore clear during continuous drilling. The 13/32-inch shank diameter fits standard SDS-Plus rotary hammer chucks without adapters.

Key Features

Installation Notes

Installation should be performed by a qualified tradesperson familiar with rotary hammer operation and applicable codes. Always wear appropriate eye and respiratory protection when drilling masonry, as silica dust is a recognized health hazard. Confirm the drill is set to the correct mode (rotary hammer or hammer-only) before engaging the bit. Inspect the carbide tip for damage before each use and retire the bit if the tip shows cracking or excessive wear.
