- Superior flexibility reduces vibration during deep or long-overhang machining.
- Improves surface finish and prevents tool breakage in unstable conditions.
- Compatible with standard carbide inserts for steel, stainless steel, and cast iron.
- Suitable for fine finishing, medium cutting, and interrupted cutting operations.
- Available in multiple shank sizes and geometries for various CNC lathes.
Compatible Inserts
- Turning Inserts: CCMT, DCMT, TCMT, VBMT, CCGT for finishing
- Boring Inserts: 11IR/16IR threading inserts for internal threading
- Grooving Inserts: MGMN, GER series for internal and external grooving
Applications
- External turning of shafts, bushings, flanges, and general steel components.
- Internal boring and finishing for precision holes and internal surfaces.
- Machining stainless steel, alloy steel, mild steel, and cast iron.
- High-speed cutting with improved vibration control.
- Interrupted cutting and heavy load operations requiring high toughness.
