Milwaukee Spline Drill Bit 2-Cutter

The Milwaukee Spline Drill Bit 2-Cutter line gives you spline shank rotary hammer bits for drilling holes in brick, block, and concrete. They are also sold as spline masonry bits or spline hammer drill bits. They are made for spline drive rotary hammers and are a good fit for professional masonry work.

Key Features:

• 2-cutter head: Two carbide cutting edges pulverize masonry as the bit turns and pounds the work surface.
• Carbide construction: Carbide nibs are vacuum brazed to a heat-treated steel body. Milwaukee's brazing formula is designed to extend bit life.
• Spline shank: The splines slide into matching splines in the hammer's drive system. This positive engagement transfers energy efficiently from the hammer to the bit.
• Efficient dust removal: The flute geometry clears debris from the hole as you drill.
• Centering point: The point helps start accurate, round holes.

These bits suit electrical, plumbing, and HVAC installation work, and any other job that needs large-diameter holes in concrete or masonry. Pick the diameter and length you need from the variants available on this page.
