Grade Details — Key Grade Characteristics

The KW10 grade is a uncoated fine-grained tungsten carbide substrate engineered for high-precision finishing applications. Key characteristics include:

• Substrate: Fine-grained uncoated carbide with high hardness and excellent wear resistance
• Coating: Uncoated — maintains sharp cutting edge for mirror-finish machining
• Grain Size: Ultra-fine 0.5 μm WC grain structure for superior edge stability
• Hardness: 92.0 HRA — ideal for precision finishing without edge deformation
• Transverse Rupture Strength: >2,800 MPa for reliable performance in continuous cuts
• Thermal Stability: Excellent heat resistance up to 800°C in dry cutting conditions

Recommended Cutting Conditions

Starting parameters for KW10 grade on typical workpiece materials (adjust based on machine rigidity and setup):

Note: Values are starting recommendations. Optimize based on machine condition, workpiece rigidity, and required surface finish. Recommended for non-ferrous materials; dry cutting acceptable for cast iron.

Operating Guidelines

• Tool Overhang: Minimize overhang to prevent vibration and ensure stable cutting. Use the shortest possible toolholder.
• Insert Seating: Ensure the insert seat is clean and free of chips before clamping. Verify proper contact with the toolholder pocket.
• Cutting Fluid: Recommended for non-ferrous materials; dry cutting acceptable for cast iron. For aluminum and copper, clean coolant prevents built-up edge formation.
• Edge Preparation: The uncoated edge is ready to use. Do not attempt additional honing or edge preparation.
• Storage: Store inserts in original packaging away from moisture and corrosive environments. Temperature range: 10°C–30°C.
• Inspection: Visually inspect cutting edges before use. Discard inserts with visible chipping, cracks, or excessive wear.

Toolholder Compatibility

This insert is compatible with standard ISO D-type (55°) turning holders. Recommended toolholder families include:

• Toolholder Series: SDJCR, SDQCR, SDUCR, SVJCR series toolholders
• Clamping System: Lever-lock or screw-clamp depending on toolholder design
• Insert Seat Angle: Must match insert clearance angle (7°)
• Hand Compatibility: Ensure toolholder hand matches insert hand (Right-Hand)
• Shank Size: Select based on machine turret and workpiece envelope (16mm–32mm common)
