Depth 35mm
Style 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).


  • Long life: Proprietary steel reduces breakage and extends stud life
  • Versatile design: Use with 11" extension for extra-deep drilling applications
  • Adaptability: Available in SDS-MAX or spline shanks and works with interchangeable drilling heads from 1-1/2" to 3-1/4"
