Our 1-piece carbide tipped core bits are ideal for drilling large holes with relatively shallow depths. The core bit cuts a kerf only. The operator must remove the inside core before deeper drilling can be accomplished. Use of centering bit 48-20-5495 is recommended (not included). Use drift key 48-20-5497 to remove the centering bit from the one-piece 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.
