Internal grooving boring bars for producing grooves, O-ring seats, and snap ring grooves inside bores. Anti-vibration design with internal coolant for clean internal grooves.
Reach into bores as small as 12mm for internal groove production.
Precise groove dimensions for O-ring and snap ring seats.
Dampened bar reduces chatter for superior groove surface quality.
Internal coolant prevents chip build-up in blind-hole grooving.
