Kyocera WNMG06T304HQ CA115P TML00281 Turning Insert - Precision Finish

Product Overview

The WNMG06T304HQ CA115P TML00281 is a premium-grade indexable carbide insert manufactured by Kyocera in Japan. Designed for CNC turning centers, this 80° rhombic diamond insert combines advanced CVD Multi-Layer (TiCN + Al₂O₃ + TiN) coating technology with a Fine-grained WC-Co carbide substrate to deliver exceptional performance in high-precision finishing and mirror-surface generation. The HQ - High Precision chipbreaker geometry ensures optimal chip evacuation and surface integrity across a wide range of cutting parameters, while the 2 two primary cutting edges provide economical machining.

ISO Designation Breakdown

Engineering Dimensions & Geometry

Grade Details — Key Grade Characteristics

The CA115P grade is a CVD Multi-Layer (TiCN + Al₂O₃ + TiN) coated carbide specifically engineered for high-performance steel machining.

• Exceptional crater wear resistance due to thick Al₂O₃ thermal barrier layer
• High adhesion strength between substrate and coating prevents flaking
• Gold-colored TiN top layer provides excellent wear visibility and built-up edge resistance
• Optimized for continuous to light-interrupted cutting conditions
• Stable performance across medium to high cutting speeds (150–350 m/min)

Substrate Properties: Hardness HRA 92.5 | Transverse Rupture Strength 2,450 MPa | Coating Color: Gold

Grade Comparison Matrix

Chipbreaker Profile

The HQ - High Precision chipbreaker features a fine-pitch serration with polished land designed for high-precision finishing and mirror-surface generation.

• Groove Depth: 0.6mm — controls chip curl radius and breaking point
• Groove Width: 1.0mm — determines chip thickness capacity and evacuation path
• Rake Angle: Positive 8°–12° (chipbreaker-dependent) — reduces cutting forces and heat generation
• Land Width: 0.3 mm (approx.) — reinforces the cutting edge for stability
• Recommended Feed Range: 0.05–0.12 mm/rev mm/rev
• Depth of Cut Range: 0.1–0.8 mm mm

Recommended Applications & Workpiece Materials

The WNMG06T304HQ with CA115P grade is optimized for the following material groups and applications:

• Low-alloy steels (ISO P2–P3) — precision finishing with mirror surfaces
• Free-machining steels (ISO P1) — excellent surface integrity
• Stainless steels austenitic (ISO M2) — low built-up edge tendency
• Tool steels pre-hardened (ISO P4–P5) — semi-finishing operations
• Hardened steels up to 45 HRC — light finishing passes

Application Map by Operation

Recommended Cutting Conditions

Note: Values are starting recommendations. Adjust based on machine rigidity, coolant application, and workpiece condition. Use lower range for interrupted cuts and higher range for continuous machining.

Operating Guidelines

• Coolant: Flood coolant (5–8% emulsion) recommended for steel; dry or compressed air acceptable for cast iron to prevent thermal shock.
• Entry Angle: Use 45°–75° approach angle for optimal chip flow and reduced notch wear.
• Edge Preparation: Ground edge — minimal honing required; do not regrind coated edges.
• Insert Change Policy: Replace when flank wear exceeds 0.3 mm or crater depth reaches 0.1 mm to maintain dimensional accuracy.
• Safety: Always use proper PPE and ensure toolholder clamping torque is 3.5–4.5 N·m for secure retention.
