• Substrate: Fine-grain WC-Co Carbide
• Coating Color: Bronze/Copper
• Hardness: HRA 92.5
• Transverse Rupture Strength: ≥ 3,500 MPa
• Primary Applications: Steel (P), Stainless Steel (M), Cast Iron (K)
• Recommended Speed: 80–250 m/min (depending on material)
• Recommended Feed: 0.10–0.40 mm/rev
• Depth of Cut: 0.5–4.0 mm

Performance Profile: Excellent balance of wear resistance and toughness. Optimized for stable to semi-interrupted cuts. Superior crater and flank wear resistance at medium-to-high speeds.

Chipbreaker Profile

The TPMN160304 features a standard precision chipbreaker optimized for triangular insert geometry and versatile turning operations.

• Land Width: 0.12–0.18 mm for balanced cutting performance
• Groove Depth: 0.10–0.15 mm for consistent chip formation
• Rake Angle: Positive 12–16° for smooth chip evacuation
• Chip Control: Reliable breaking across 0.08–0.25 mm/rev feed range
• Best For: General CNC turning, semi-finishing, light roughing

Recommended Applications & Workpiece Materials

The TPMN160304 with CA310 grade is optimized for the following material groups:

• Carbon Steel (C45, C50, C60): Excellent — continuous to lightly interrupted cuts, high speed capability
• Alloy Steel (4140, 4340, 8620): Excellent — balanced wear resistance and toughness
• Stainless Steel (304, 316, 420): Very Good — reduced built-up edge tendency due to PVD coating
• Gray Cast Iron (GG25, GG30): Very Good — dry or wet machining, good crater resistance
• Ductile Cast Iron (GGG40, GGG50): Good — moderate speeds, stable cutting edges
• Tool Steel (H13, D2, O1 annealed): Good — reduced speeds for hardness >250 HB
• Free-Machining Steel (12L14, 1215): Excellent — high speeds, excellent finish

Values are starting recommendations. Optimize based on machine rigidity, coolant delivery, and workpiece stability. Wet cutting recommended for stainless steel and high-temp alloys.

Operating Guidelines

Best practices to maximize tool life and surface quality:

• Coolant: Flood coolant recommended for steel and stainless steel at speeds >150 m/min. Minimum 5% soluble oil concentration. For cast iron, dry machining acceptable at moderate speeds.
• Edge Preparation: As-supplied T-land edge preparation (0.05–0.10 mm × 20°). Do not re-hone; PVD coating integrity is compromised by manual honing.
• Tool Overhang: Keep toolholder overhang ≤ 1.5× shank diameter for boring. For external turning, rigid setup essential for 0.4 mm corner radius.
• Runout: Maintain spindle runout < 0.01 mm TIR. Excessive runout accelerates flank wear and chipping.
• Entry/Exit: Use ramp entry or radius approach. Avoid direct plunge into workpiece. Reduce feed by 30% during entry and exit phases.
• Chip Management: Ensure chip conveyor or enclosure is rated for triangular insert chips. Long chips indicate feed or speed is too low.
• Insert Change: Replace when flank wear (VB) reaches 0.3 mm, or when crater wear (KT) exceeds 0.15 mm. Do not wait for catastrophic failure.
• Storage: Keep original packaging sealed until use. Avoid contact with corrosive agents. Handle with gloves to prevent coating contamination.

Toolholder Compatibility

Compatible Kyocera and ISO-standard toolholder families:

Verify holder pocket size matches insert IC (≈ 9.525 mm (3/8")) and thickness (3.18 mm). Use precision torx screws (T-15) for secure clamping. Recommended clamping torque: 2.5–3.5 N·m.
