Product Overview
The Kyocera DCMX070204WP is a premium-grade 55° Rhombic carbide insert engineered for Precision Finishing operations in modern CNC turning centers. Featuring the advanced CA125P PVD-coated substrate and the WP chipbreaker geometry, this insert delivers exceptional wear resistance, predictable tool life, and superior surface integrity across a broad spectrum of ferrous materials.
With an inscribed circle of 7.94mm (5/16"), thickness 2.38mm (3/32"), and a 0.4mm nose radius, the DCMX070204WP is optimized for finishing to medium machining. Whether you are running high-volume production or precision prototype work, this insert provides the consistency and reliability that aerospace, automotive, and general engineering shops demand.

Grade Details — Key Grade Characteristics
CA125P is a high-performance PVD-coated carbide grade developed by Kyocera for universal turning of steel, stainless steel, and cast iron. The multi-layer PVD coating combines titanium aluminum nitride (TiAlN) with an optimized binder phase to achieve:
- Superior Wear Resistance: Extended tool life in continuous and lightly interrupted cuts, reducing cost per edge.
- High Thermal Stability: Coating integrity maintained at elevated temperatures, enabling higher cutting speeds.
- Balanced Toughness: Substrate engineered to resist chipping and fracture under variable machining conditions.
- Low Coefficient of Friction: Reduced built-up edge (BUE) tendency when machining sticky materials like austenitic stainless steel.
- Consistent Performance: Tight manufacturing tolerances ensure batch-to-batch predictability for automated production.
Grade Comparison Matrix
| Grade | Coating | Material Range | Application Range | Toughness |
|---|---|---|---|---|
| CA125P | PVD Coated | Steel, Stainless, Cast Iron | General to medium | ★★★★☆ |
| CA115P | PVD Coated | Steel, Cast Iron | Light to medium | ★★★☆☆ |
| CA530 | CVD Coated | Steel, Cast Iron | Medium to heavy | ★★★★☆ |
| CA6515 | CVD Coated | Steel, Hardened Steel | Heavy roughing | ★★★★★ |
Chipbreaker Profile
The WP chipbreaker on the DCMX070204WP is precision ground for low cutting forces. Key geometric attributes include:
- Land Width: Optimized for finishing to medium machining to minimize cutting forces and heat generation.
- Rake Angle: Positive rake design promotes smooth chip flow and reduces burr formation.
- Chip Groove Depth: Calculated to curl and break chips into manageable lengths for safe evacuation.
- Edge Preparation: Light to Medium honing balances sharpness with edge strength for the intended application range.
Recommended Applications & Workpiece Materials
| Material Group | ISO Code | Hardness Range | Suitability |
|---|---|---|---|
| Carbon & Alloy Steels | P.1 – P.4 | ≤ 350 HB | ★★★★★ Excellent |
| Stainless Steels (Austenitic) | M.1 – M.2 | ≤ 250 HB | ★★★★☆ Very Good |
| Stainless Steels (Martensitic) | M.3 | ≤ 325 HB | ★★★★☆ Very Good |
| Gray & Ductile Cast Iron | K.1 – K.3 | ≤ 300 HB | ★★★★☆ Very Good |
| Tool & Die Steels | P.5 | ≤ 45 HRC | ★★★☆☆ Good (reduce speed) |
Application Map by Operation
| Operation | Rating | Recommendation |
|---|---|---|
| External Turning | ★★★★★ | Excellent for semi-finish and finish turning |
| Internal Turning | ★★★★☆ | Good for medium-depth boring operations |
| Face Turning | ★★★★☆ | Reliable for facing with moderate depths |
| Profiling | ★★★☆☆ | Acceptable for simple contours; use smaller nose radius for complex profiles |
Recommended Cutting Conditions
Parameters are starting recommendations for stable setups with adequate coolant. Adjust based on machine rigidity and workpiece condition.
| Workpiece Material | Vc (m/min) | f (mm/rev) | ap (mm) |
|---|---|---|---|
| Carbon Steel | 200–280 | 0.10–0.25 | 0.3–1.0 |
| Alloy Steel | 180–250 | 0.08–0.20 | 0.3–0.8 |
| Stainless Steel | 140–200 | 0.08–0.18 | 0.2–0.6 |
| Cast Iron | 180–260 | 0.10–0.25 | 0.3–1.0 |
Operating Guidelines
- Suitable for continuous and light interrupted cuts; avoid heavy shocks
- Apply consistent coolant flow to extend tool life and improve chip evacuation
- Optimize feed rate to balance productivity with surface finish requirements
- Use rigid clamping systems to minimize vibration during semi-finishing
- Periodically check insert seat condition to prevent micro-chipping
