Milwaukee Tool 48-20-8884 3/16 in Carbide Hammer Drill Bit

Product Description

The MILWAUKEE TOOL 48-20-8884 is a carbide-tipped rotary and hammer drill bit from the SHOCKWAVE Impact Duty series, designed for drilling into masonry, concrete, and similar hard substrates. The bit features a 1/4-inch hex shank for quick, tool-free chuck changes in hex-compatible drills and hammer drills. At 3/16 inch in diameter with a 4-inch flute length and a 6-inch overall length, it is well-suited for anchor hole placement and through-hole drilling in wall, floor, and ceiling applications. Sold in a 3-piece set, this bit is a practical choice for HVAC, plumbing, and electrical trades that routinely drive fasteners and anchors into concrete or block.

This bit is intended for use in rotary drills and hammer drills equipped with a 1/4-inch hex chuck or quick-change adapter. Typical applications include drilling anchor holes for equipment mounting, through-hole work for conduit or pipe penetrations, and general masonry drilling in residential and light commercial settings. The SHOCKWAVE Impact Duty designation indicates the bit is engineered to handle the repeated shock loading produced by hammer drill operation.

Installation Notes

Installation should be performed by a qualified tradesperson following applicable codes and jobsite safety requirements. Always power down and disconnect the drill before changing bits. Wear appropriate eye and respiratory protection when drilling into concrete or masonry, as carbide bits generate fine dust and debris. Do not use this bit in SDS-style chucks without a proper hex adapter.
