Kyocera SPMR090304 CA115P TML00385 Positive Insert - General Turning

Product Overview

The SPMR090304 CA115P TML00385 is a premium-grade indexable carbide insert manufactured by Kyocera in Japan. Designed for CNC turning centers, this square insert combines advanced CVD Multi-Layer (TiCN + Al₂O₃ + TiN) coating technology with a Fine-grained WC-Co carbide substrate to deliver exceptional performance in universal turning and custom grinding applications. The Standard Geometry chipbreaker geometry ensures optimal chip evacuation and surface integrity across a wide range of cutting parameters, while the 4 four usable 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

Chipbreaker Profile

The SPMR090304 features a standard flat-top geometry with no dedicated chipbreaker groove, designed for universal turning and custom grinding applications.

• Top Surface: Flat with neutral rake — suitable for custom grinding
• Edge Preparation: Molded / Round edge — reliable for general machining
• Rake Angle: Neutral 0° — compatible with negative and positive rake holders
• Recommended Feed Range: 0.10–0.30 mm/rev mm/rev
• Depth of Cut Range: 0.5–3.0 mm mm

Recommended Applications & Workpiece Materials

The SPMR090304 with CA115P grade is optimized for the following material groups and applications:

• Carbon steels (ISO P1–P4) — general turning and facing
• Alloy steels (ISO P3–P5) — balanced wear and fracture resistance
• Stainless steels (ISO M1–M3) — moderate cutting speeds with good finish
• Tool steels (ISO P5–P6) — reliable performance in general machining
• Cast steels and forgings — consistent tool life in varied cuts

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: Molded / Round 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.
