Product Overview
The Kyocera TPMX110302WP is a premium indexable carbide turning insert engineered for demanding CNC machining environments. Featuring the advanced CA125P PVD-coated grade, this insert delivers exceptional performance in steel machining applications. The Triangular (60°) geometry with 11° clearance angle ensures smooth cutting action and reduced cutting forces, making it ideal for medium machining, semi-finishing.
With an inscribed circle of 11.0 mm (7/16"), thickness of 3.18 mm (1/8"), and a corner radius of 0.2 mm, the TPMX110302WP provides precise dimensional control and consistent surface finishes down to Ra 0.4–0.8 µm. The specialized Wide Positive (WP) chipbreaker geometry guarantees Optimal chip curling across the recommended parameter range.

Chipbreaker Profile
The Wide Positive (WP) chipbreaker is optimized for medium machining, semi-finishing. Its unique land width and groove geometry ensure reliable chip formation and evacuation at the specified feed rates.
| Parameter | Wide Positive (WP) |
|---|---|
| Application Category | Medium |
| Recommended Feed (fn) | 0.10–0.30 mm/rev |
| Depth of Cut (ap) | 0.5–3.0 mm |
Recommended Applications & Workpiece Materials
- Carbon Steel (C45, C60): Excellent performance in continuous and light interrupted turning.
- Alloy Steel (4140, 4340): Balanced wear resistance and toughness for medium-speed operations.
- Stainless Steel (304, 316): Superior crater resistance prevents built-up edge formation.
- Tool Steel (H13, D2): Reliable performance in semi-finishing and finishing passes.
- Free-Cutting Steel: Optimal chip curling at high feed rates.
Application Map by Operation
| Operation Type | Suitability | Notes |
|---|---|---|
| External Longitudinal Turning | ★★★★★ | Primary application; stable chip control |
| Face Turning | ★★★★☆ | Excellent for facing up to 3.0 mm DOC |
| Internal Boring | ★★★☆☆ | Use with appropriate boring bars |
| Profiling / Contouring | ★★★★☆ | Small nose radius enables fine detail |
| Grooving / Parting | ★★☆☆☆ | Not recommended; use dedicated inserts |
Recommended Cutting Conditions
| Workpiece Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | Depth of Cut ap (mm) |
|---|---|---|---|
| Carbon Steel | 120–200 | 0.08–0.30 | 0.2–3.0 |
| Alloy Steel | 108–180 | 0.08–0.30 | 0.2–3.0 |
| Stainless Steel | 100–160 | 0.08–0.24 | 0.2–2.4 |
| Cast Steel | 80–140 | 0.08–0.30 | 0.2–3.0 |
Note: Values are starting recommendations. Optimize based on machine rigidity, coolant application, and workpiece condition.
Operating Guidelines
- Coolant: High-pressure water-soluble coolant recommended for steel; minimum 5% concentration.
- Entry Angle: Maintain 91–95° tool entering angle for optimal chip control and reduced notch wear.
- Run-in: Reduce cutting speed by 15% for the first 5 minutes to stabilize the cutting edge.
- Tool Overhang: Minimize overhang to prevent vibration; use shortest possible toolholder.
- Inspection: Check for flank wear (VB max 0.3 mm) or crater depth (KT max 0.1 mm) before re-indexing.
- Edge Preparation: Do not touch the cutting edge with bare hands; oil residue affects coating adhesion.
Toolholder Compatibility
The TPMX110302WP is compatible with the following ISO toolholder families:
| Holder Family | Application |
|---|---|
| PTFNR/L, PTGNR/L (external); X-type specialized holders | External / Internal turning |
| Standard ISO clamp (lever lock or screw clamp) | All standard operations |
Ensure the holder clamping mechanism is in good condition and provides uniform pressure across the insert seat. A worn seat can cause micro-vibration and premature edge failure.
