Spline One-Piece Core Bits

MILWAUKEE’s One-Piece Carbide Tipped Core Bits are ideal for drilling large holes where the depth is relatively shallow. The core bit cuts a kerf only. The inside core must be removed by the operator before deeper drilling can be accomplished. Centering bit 48-20-5495 is included. Use drift key 48-20-5497 (not included) to remove centering bit from the onepiece core bit. The one-piece core bits are available in SDS Max or Spline shanks. They come in a variety of diameters ranging from 1-1/2" to 6" with overall lengths of 11-3/8" or 22" and a drilling depth of 3". The asymmetric tooth pitch with alternating tooth geometries creates faster material pulverization. The one-piece design maximizes energy transfer and the thick wall core body is durable even in large hammers. The fluted core exterior minimizes friction loss and removes debris faster.

  • Asymmetrical and Alternating Teeth for Faster Material Pulverization
  • Thick-Wall Core Body for Durability Even in Large Hammers
  • Optional: Centering Tip to Reduce Bit Walking and Create Exact Spot Drilling
