Milwaukee 48-20-8880 Carbide Multi-material Drill Bit 3-pack

Product Description

The Milwaukee 48-20-8880 is a SHOCKWAVE Impact Duty carbide-tipped multi-material drill bit rated for drilling through wood, metal, plastic, and masonry. Measuring 1/8 inch in diameter by 2 inches in flute length and 3.5 inches overall, this bit ships in a pack of three. The carbide tip provides extended cutting life compared to standard high-speed steel bits, and the shank geometry is engineered for use with impact drivers as well as conventional drills. Trades that regularly switch between substrate types will find the multi-material rating practical on mixed installations.

This bit is suited for residential and light commercial work where installers encounter varied materials in a single run — framing lumber, sheet metal, PVC conduit, and concrete block or brick. Electricians, plumbers, and HVAC technicians drilling through mixed-construction walls and floors are the primary users. The 1/8 inch diameter is common for pilot holes, wire-pull guide holes, and small-diameter penetrations. The three-piece pack supports job-site redundancy when bit wear or breakage is a concern.

Key Features

• Carbide tip for extended durability across hard and abrasive materials
• Multi-material rated: wood, metal, plastic, and masonry in a single bit
• Impact driver compatible shank withstands high-torque rotary impact forces
• 1/8 inch diameter suits pilot holes, guide holes, and small penetrations
• 3.5 inches overall length provides reach in tight framing cavities
• Sold as a pack of three for job-site redundancy

Compatibility

Designed as a general-purpose multi-material drill bit compatible with standard 1/4 inch hex-shank impact drivers and keyed or keyless drill chucks accepting 1/8 inch round or hex shanks.

Installation Notes

This bit is installed and used by electricians, plumbers, HVAC technicians, and general tradespeople. Always confirm the driver or drill is powered off and the battery is removed or the tool is unplugged before changing bits. When drilling into masonry, use firm steady pressure and allow the carbide tip to do the work — forcing the bit accelerates tip wear. Follow applicable codes such as the NEC or IPC when sizing penetrations through fire-rated assemblies, and apply listed firestop material as required after drilling.
