Kyocera CCMT060202GK CA125P TMK00314

Product Overview

The CCMT060202GK is a premium-grade indexable carbide turning insert manufactured by Kyocera. Featuring the advanced CA125P substrate with a high-performance PVD multi-layer coating, this general turning insert is engineered for semi-finishing to medium roughing. The Rhombic 80° geometry combined with a 0.2mm nose radius ensures exceptional surface finish, dimensional stability, and extended tool life in demanding CNC environments.

Ideal for machining carbon steels, alloy steels, and select stainless grades, the CCMT060202GK delivers consistent performance across high-volume production runs. Every insert is produced to exacting ISO standards and undergoes rigorous quality control before shipment.

Grade Details – Key Grade Characteristics

The CA125P grade represents a balanced solution for steel machining applications, combining a fine-grained carbide substrate with a modern PVD coating stack optimized for heat and wear resistance.

• Substrate: Fine-grained tungsten carbide (WC-Co) with high cobalt content for improved toughness
• Coating: PVD multi-layer (TiAlN-based) – exceptional heat resistance and adhesion strength
• Color Code: Copper-bronze (typical CA125P finish)
• Hardness: ~92.5 HRA (1530 HV30)
• Transverse Rupture Strength: >3500 N/mm²
• Application Range: ISO P15-P30 (steels), extends to stainless and cast iron

Chipbreaker Profile

GK – General Turning

The General Turning chipbreaker on the CCMT060202GK is specifically designed for semi-finishing to medium roughing. The groove geometry promotes tight chip curling and controlled breakage, preventing chip entanglement and protecting both the insert edge and the workpiece surface. The land width and rake angle are optimized for the 0.2mm nose radius to maintain edge integrity under the recommended feed and depth-of-cut ranges.

Recommended Applications & Workpiece Materials

The CA125P grade with the GK – General Turning geometry is best suited for the following materials and conditions:

• Carbon Steels: C35, C45, C60 – excellent chip control and surface finish
• Alloy Steels: 42CrMo4, 16MnCr5, 34CrNiMo6 – balanced wear and toughness
• Stainless Steels: 304, 316, 410 – reduced built-up edge tendency
• Cast Irons: GG25, GG30 – acceptable at reduced speeds with adequate coolant
• Tool Steels: H13, D2 – light finishing passes recommended

Operating Guidelines

To maximize insert life and maintain part quality, observe the following best practices:

• Coolant: High-pressure coolant (70–100 bar) recommended for chip evacuation and heat management. For finishing operations, minimal quantity lubrication (MQL) is acceptable.
• Entry Angle: Maintain 95° for external turning, 93° for internal boring to minimize radial forces.
• Chip Control: Verify chipbreaker engagement at the selected feed rate. Adjust feed if chips are not properly broken.
• Edge Preparation: CA125P features a honed T-land (0.05–0.10 mm) for edge stability. Do not re-sharpen.
• Storage: Store in original packaging away from moisture and corrosive environments. Avoid direct contact between inserts to prevent chipping.
• Safety: Always use appropriate PPE when handling inserts. Carbide edges are extremely sharp.
