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):

MaterialCutting Speed Vc (m/min)Feed fn (mm/rev)Depth of Cut ap (mm)
Gray Cast Iron120–2000.08–0.200.5–2.0
Aluminum Alloy200–4000.05–0.250.1–1.5
Copper / Brass150–3000.06–0.200.2–1.5
Titanium Alloy30–600.08–0.150.5–1.5
Plastics / Composites200–5000.05–0.300.1–2.0

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 Compatible turning holders. Recommended toolholder families include:

  • Toolholder Series: Standard ISO 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 (Neutral)
  • Shank Size: Select based on machine turret and workpiece envelope (16mm–32mm common)
