||Replacement Threaded Stud
The Milwaukee® 2-1/2" Threaded Stud guides your Turbo Tunnel Bit for more accurate drilling in block, brick and concrete. Used in the drilling end of the Turbo Tunnel Bit, the threaded stud acts as a bit guide/center punch until the carbide teeth of the Turbo Tunnel bit grab into the masonry. The threaded stud works with a variety of Turbo Tunnel Bit sizes and with spline or SDS-MAX 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).
