Milwaukee 48-20-8893 Carbide Multi-material Drill Bit 1/2x12in 3pk

Product Description

The MILWAUKEE ELECTRIC TOOL CORP 48-20-8893 is a SHOCKWAVE Impact Duty carbide-tipped multi-material drill bit designed to bore through masonry, tile, wood, metal, and other mixed substrates in a single tool setup. The bit measures 1/2 inch in diameter with a 12-inch overall length and a 10-inch usable cutting depth, giving technicians and tradespeople the reach needed for through-wall and deep-penetration applications. Carbide construction provides the hardness required to sustain repeated impact-driver use without premature tip failure. This bit ships as a 3-pack, making it a practical stocking unit for shops and service vehicles.

This bit is suited for commercial and residential installation work where drilling through mixed materials is routine — electrical rough-in, HVAC penetrations, plumbing stub-outs, and general construction applications. The SHOCKWAVE geometry is engineered for use with impact drivers and hammer drills, making it a common choice for electricians, plumbers, HVAC installers, and general contractors who regularly drive fasteners and drill through concrete block, brick, fiber cement, and similar substrates in a single pass.

Installation Notes

This bit is typically installed and operated by electricians, plumbers, HVAC technicians, and general construction tradespeople.
