High-Precision Grooving & Parting Inserts for Steel, Stainless Steel, Titanium, and Cast Iron

Our Carbide MGMN Grooving Insert Series is engineered for high-precision external and internal grooving, parting-off, and multi-directional turning operations.
Designed for stability, long tool life, and consistent chip control, the MGMN series supports high-speed machining and demanding production environments across automotive, mold making, aerospace, and precision engineering.

With optimized geometries (G, M, J, DR, GB, T types) and our proprietary carbide grades, this series ensures reliable performance on steel, stainless steel, titanium alloys, and cast iron—helping manufacturers reduce tooling cost, improve efficiency, and maintain tight tolerances.

Key Features & Benefits

✔ Precision Grooving Performance

• Stable cutting edge design ensures consistent groove width and surface finish.

• Optimized cutting geometry for smooth, vibration-free machining even in narrow groove operations.

✔ Superior Chip Control

• Dedicated chip-breaker designs (G / M / J / DR / T / GB) ensure effective chip evacuation.

• Prevents chip packing in deep grooves and improves toolholder protection.

✔ Grade Options for Every Material

Our premium carbide grades offer a balance of wear resistance, toughness, and thermal stability for various applications:

• Steel: PA1025, PA2025, PA4225

• Stainless Steel: MA1328

• Steel & Stainless Steel (Universal): PA1825

• Titanium Alloy: SA1530

• Cast Iron: KA3115

✔ Cost-Effective Operation

• Strong edge integrity + PVD/CVD coatings = extended tool life.

• Stable insert-holder clamping reduces downtime and increases process reliability.

✔ Wide Range of Widths

Available from 1.5 mm to 5.0 mm, suitable for narrow, medium, and heavy grooving or parting operations.
