Grade Details - Key Grade Characteristics
Grade KW10 is an uncoated fine-grain carbide grade engineered for high-precision finishing and semi-finishing operations. It offers:
- Excellent wear resistance on non-ferrous and cast iron materials
- Superior edge sharpness for high-precision finish requirements
- High thermal stability in dry and wet machining environments
- Low cutting forces reducing workpiece deflection
- Optimal performance in stable cutting conditions

Chipbreaker Profile
The TPGH090204L features a precision-ground chipbreaker geometry optimized for reliable chip management. The uncoated substrate ensures minimal built-up edge when machining aluminum, copper, and cast iron alloys. The positive rake angle design promotes smooth chip flow away from the cutting zone, preventing chip recutting and improving surface integrity.

Note: Values are starting recommendations. Optimize based on machine rigidity, workpiece condition, and coolant application.
Operating Guidelines
- Ensure proper insert seating and clamping force to prevent micro-vibration
- Use high-pressure coolant for titanium and heat-resistant alloys
- Maintain consistent feed rates to prevent built-up edge on aluminum
- Verify toolholder overhang is minimized for boring operations
- Replace insert when flank wear exceeds 0.15mm or when surface finish degrades
- Dry machining is acceptable for cast iron; coolant recommended for non-ferrous materials
Toolholder Compatibility
The TPGH090204L is compatible with standard ISO/ANSI toolholders featuring the TPGH pocket designation. Recommended toolholder series include:
- External turning: SVJCR/L, SVVBN, SVUBR (for TPGH inserts)
- Boring bars: SCLCR/L, STFCR/L (for internal operations)
- Copying/profiling: SVJCR/L with appropriate approach angle
- Verify toolholder clamping system (lever lock, screw clamp, or top clamp) matches insert thickness
