Milwaukee's Turbo Tunnel Bits are ideal for large hole drilling where the depth of the hole exceeds the practicality of a Core Bit. Holes up to 36 in. deep can be drilled, however, drilling speed and efficiency are diminished by the use of multiple extensions. Use with SDS Max or Spline Drive Adapters depending on the Hammer used. Can also use 11 in. extension 48-20-5079.
- 2-5/8 in. Dia, turbo tunnel head
- Interchangeable drilling heads
- SDS-Max or spline shanks available
- 11 in. extensions, 48-20-5079, can be coupled for extra deep drilling applications
