| N | Clearance Angle | N — 0° Clearance (Negative Insert) |
| M | Tolerance Class | M — Medium Tolerance (±0.05 mm) |
| M | Hole / Fixation | M — Central Hole, Double-Sided (No Chipbreaker Groove) |
| 12 | Inscribed Circle (IC) | 12.7 mm (1/2") |
| 04 | Insert Thickness (S) | 4.76 mm (3/16") |
| 12 | Nose Radius (rε) | 1.2 mm |
3. Engineering Dimensions & Geometry
| Dimension | Value | Notes |
|---|---|---|
| Inscribed Circle (IC) | 12.7 mm (1/2") | Standard CNMM12 size |
| Thickness (S) | 4.76 mm (3/16") | Negative insert geometry |
| Nose Radius (rε) | 1.2 mm | Affects surface finish & strength |

| Edge Preparation | T-Land with Honing (Honed edge for strength) | Optimized for heavy-duty roughing |
4. Grade Details — CA525
CA525 is a PVD-coated carbide grade engineered for high-performance steel machining. The multilayer coating architecture combines TiAlN-based layers with an optimized substrate, delivering:
- Outstanding wear resistance at elevated cutting temperatures
- Superior adhesion strength between coating and substrate
- Excellent thermal shock resistance for interrupted cuts
- Reduced built-up edge (BUE) tendency on alloy steels
5. Grade Comparison Matrix
| Grade | Coating | Primary Use | Speed Range | Material Focus |
|---|---|---|---|---|
| CA525 | PVD (TiAlN) | General / Semi-Finish | Medium–High | Steel, Stainless Steel |
| CA530 | PVD | Roughing | Medium | Steel, Cast Iron |
| CA515 | PVD | Finishing | High | Steel, Precision Parts |
| CA550 | CVD | Heavy Roughing | Low–Medium | Cast Iron, Hard Steel |
6. Chipbreaker Profile — PX
The PX chipbreaker geometry is specifically engineered for heavy-duty roughing, large depth of cut. Key characteristics include:
- Polished edge with reinforced land for heavy-duty finishing
- Optimized land width for reduced cutting forces
- Enhanced chip curl radius for reliable chip evacuation
- Stable edge line for consistent part geometry
7. Recommended Applications & Workpiece Materials
| Material Group | ISO Code | Suitability | Notes |
|---|---|---|---|
| Carbon Steel | P1.1–P2.5 | ★★★★★ Excellent | Primary application range |
| Alloy Steel | P3.0–P4.0 | ★★★★★ Excellent | High cutting speeds possible |
| Stainless Steel | M1.0–M2.0 | ★★★★☆ Very Good | Reduce speed by 15–20% |
| Cast Iron | K1.0–K3.0 | ★★★☆☆ Good | Suitable for grey & ductile iron |
| Hardened Steel | H1.0–H2.0 | ★★☆☆☆ Fair | Light cuts only (<45 HRC) |
8. Application Map by Operation
| Operation | Suitability | Recommended DOC (ap) | Feed (fn) |
|---|---|---|---|
| External Turning | ✓ Primary | 1.0–6.0 mm | 0.25–0.60 mm/rev |
| Internal Turning | ✓ Suitable | 0.5–2.0 mm | 0.10–0.30 mm/rev |
| Face Turning | ✓ Suitable | 0.5–2.5 mm | 0.12–0.35 mm/rev |
| Profiling | ✓ Good | <1.0 mm | 0.08–0.20 mm/rev |
| Grooving | ○ Limited | <0.5 mm | 0.05–0.15 mm/rev |
9. Recommended Cutting Conditions
Values are starting recommendations for continuous cuts in carbon steel (P2.0). Adjust based on machine rigidity, workpiece condition, and desired tool life.
| Parameter | Roughing | Semi-Finish | Finishing |
|---|---|---|---|
| Cutting Speed (Vc) | 120 m/min | 170 m/min | 220 m/min |
| Feed Rate (fn) | 0.60 mm/rev | 0.42 mm/rev | 0.25 mm/rev |
| Depth of Cut (ap) | 6.0 mm | 3.5 mm | 1.0 mm |
10. Operating Guidelines
- Coolant: High-pressure coolant (70+ bar) recommended for chip control and heat dissipation. Use water-soluble coolant at 6–8% concentration.
- Rigidity: Ensure minimal overhang and rigid toolholder clamping. Vibration reduces tool life by 30–50%.
- Entry / Exit: Use chamfered entry or radial approach to avoid shock loading on the cutting edge.
- Edge Preparation: Do not re-sharpen or re-coat. Use genuine inserts for certified performance.
- Inspection: Check insert seat and clamping lever for wear before each indexing.
11. Toolholder Compatibility
| Holder Series | Style | Insert Size | Approach Angle |
|---|---|---|---|
| MCLNR / MCLNL | External, 95° | 12 (CNMM12) | 95° |
| MCBNR / MCBNL | External, 75° | 12 (CNMM12) | 75° |
| SCLCR / SCLCL | Internal, 95° | 12 (CNMM12) | 95° |
| SCBR / SCBL | Internal, 75° | 12 (CNMM12) | 75° |
All holders must feature lever-lock (G/M-type) clamping for secure insert retention. Verify holder seat condition before installation.
12. Packaging & Ordering Information
- Packaging: Each insert is individually sealed in protective blister packs. Standard pack quantity: 10 inserts per box.
- MPN: TAC01186 — Use this part number for all procurement and warranty claims.
- Traceability: Every batch is laser-marked with production code and date for full traceability.
