The AFX roofbolter, designed to be a key component in automated roofbolting systems, is a heavy-duty, low-maintenance drill feed with increased feed thrust for faster drilling in large holes or difficult roof conditions. Four models are available with a full range of retracted and extended lengths to meet virtually all roofbolting needs.

Designed for reliability

  • Hardened, corrosion-resistant slide tube rod structure
  • Sealed, automatically lubricated skid blocks to eliminate wear to the hardened chrome slide bars
