Grooving/Cut-off Turning Inserts
MZG Grooving/Cut-off Turning Inserts represent the ultimate solution for precision machining. Our professional tooling system is engineered to create precisely dimensioned grooves or completely separate components from bar stock, delivering unparalleled performance in critical industries including automotive, aerospace, mold and die, medical devices, and general engineering.
Precision Grooving & Cut-Off
Engineered for creating precisely dimensioned grooves and complete separation of components from bar stock with unparalleled accuracy and surface finish quality.
Advanced Chip Management
Diverse chipbreaker geometries tailored for different materials, ensuring effective chip curling, breaking, and evacuation to prevent tool entanglement.
Superior Durability
Built on high-quality carbide substrates with advanced PVD/CVD coatings, providing extreme hardness, wear resistance, and thermal shock resistance.
Product Performance
The superior performance of MZG's Grooving/Cut-off inserts is rooted in a comprehensive design philosophy. We offer not just individual solutions but a complete, systematic family of tools designed to tackle a vast spectrum of machining challenges.
Our inserts deliver high precision and superior surface finish through precision-ground cutting edges paired with optimized geometric chipbreakers and nose radii. This ensures tight dimensional tolerances critical for sealing grooves, O-ring grooves, and precise mating surfaces.

Machining Applications
- External Grooving/Cut-off: Radial cutting on outer diameter of workpiece, the most common application for creating precise grooves or complete separation.
- Internal Grooving: Machining grooves inside a bore, demanding higher tool rigidity and effective chip evacuation for complex internal features.
- Face Grooving: Axial cutting on workpiece face, often used to create complex annular grooves for sealing applications.
- Small Parts Machining: CTP and TKF series excel on Swiss-type lathes for efficient production of minute, precise parts with complex grooves.
Machining Recommendations
- Constant Surface Speed (G96): Programming with CSS is strongly recommended to prevent premature tool wear and maintain consistent cutting conditions.
- Cut-off Strategy: Reduce feed rate to 50% for the last 1-2mm of cut to mitigate parting impact and compensate for insufficient surface speed at center.
- Chip Management: Specialized chipbreaker geometries for different materials ensure effective chip control and prevent surface damage.
- Tool Selection: Match insert series to specific applications - TGF/GBA for general, CTP/TKF for small parts, SP for profiling operations.
