Milwaukee's Core Bits are ideal for large hole drilling where depth is relatively shallow. The Core Bit cuts a kerf only. The usable depth of Thick Wall Core Bits is 4-3/8 inch. The inside core must be removed by the operator before deeper drilling can be accomplished. The Thin Wall construction is ideal for smaller hammers and newer concrete. A 7-1/2 inch extension is available to allow for the deeper holes to be drilled. The appropriate (dependant on the diameter) SDS Plus Plus drive Shank must be used to drive the Core Bit. Use of Center Pin and Guide Plate is not recommended for positioning and starting a 1-1/8 inch hole. Thin Wall Core Bits are available from 1 inch to 6 inch diameters. See Thick Wall Core Bits for cured/seasoned concrete or use with larger hammers.
