The Milwaukee® LHS 3-1/2" Thick Wall Carbide-Tipped Core Bit with Center Bit is ideal for large hole drilling in concrete where the depth is relatively shallow. The Core Bit cuts a kerf only, so you must remove the inside core before deeper drilling can be completed. The sturdy center bit keeps the core bit in place for faster, cleaner cuts. Available
with SDS-MAX or spline shanks.
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).
