Description
CARBIDE TURNING INSERTS VCMT
VCMT carbide turning inserts are single-sided, positive-geometry triangular (rhomboid) inserts featuring a 7° relief (clearance) angle. These inserts are designed primarily for semi-finishing and finishing operations, providing wear resistance, stable cutting edges, and efficient chip control. They are suitable for machining steel, cast iron, and non-ferrous alloys.
Made from cemented carbide (WC-Co) and often CVD or PVD coated (TiN, TiCN, Al₂O₃, TiAlN), VCMT inserts provide thermal stability, durability, and long tool life, ensuring reliable performance in moderate cutting conditions.

• Relief Angle: 7° (positive geometry)
• Cutting Edges: Single-sided — 2 usable cutting edges
• Mounting Type: Clamp or screw-on (compatible with ISO standard triangular insert holders)
• Coatings: CVD or PVD — TiN, TiCN, Al₂O₃, TiAlN (depending on grade)
• Application Type: Semi-finishing and finishing, light-to-medium cuts

Materials & Applications
VCMT carbide inserts are ideal for operations requiring high surface finish quality, moderate cutting forces, and effective chip evacuation.
Typical Workpiece Materials:
• Steel (carbon and alloy) — finishing and semi-finishing
• Cast Iron (gray and ductile) — suitable with proper grades for stability and chip control
• Non-Ferrous Metals — appropriate grades/coatings recommended for thermal and wear management
Common Operations:
• Semi-finishing and finishing of components
• Light to medium turning requiring consistent chip control
• External and internal turning where triangular insert geometry is beneficial
• General purpose turning with balanced finish and productivity

Advantages & Performance
• Efficient Chip Control: Optimized geometry ensures smooth chip flow and prevents clogging
• Stable Cutting Edge: Positive geometry and solid insert base resist edge breakage and vibration
• Multi-Index Economy: Triangular single-sided design offers multiple indexings, reducing cost per part
• Versatile Use: Suitable across ISO material groups P, M, K with correct grade selection
• Balanced Finish & Durability: Provides a compromise between tool life and surface quality
