Slip-Fixed Renewable Bushings
Type SF

  • The "Two-in-One" Bushing: Fixed mode and slip position options on one knurled head! — flexibility lowers your inventory costs
  • Knurled head for easier handling — just turn and lift
  • Used with liner, permanently pressed into drill jig
  • Fixed mode for runs longer than life of bushing. Held in place by lockscrew or clamp which fits a milled recess in the head
  • Slip mode for multiple operations in the same holes (such as drilling followed by reaming) — without disturbing the workpiece
  • O.D. has a slip fit tolerance for easy insertion or removal from the liner

All slip fit bushings are lapped, honed, or ground in the I.D. Bushings with I.D.'s of 1/8" to 1" are concentric within .0003" T.I.R to the O.D. Other I.D. sizes are held within .0005" T.I.R.

No-Counterbore bushings are standard with ACME.
