The Milwaukee® Replacement Center Bit works with core bits from 1-1/2" to 5" for drilling large, shallow holes in concrete, block and brick. The center bit minimizes walking for more accurate cuts.
The Large Hole Drilling System offers maximum versatility
to suit a variety of jobsite applications, hammers and depths. Simply choose an LHS core bit, tunnel bit or 4-cutter fluted bit in the size you need and add a spline shank or SDS-MAX shank adapter. For greater lengths, add 11" extensions (48-20-5079).
