Product Overview
The Kyocera TBMT060104DP 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 5° clearance angle ensures smooth cutting action and reduced cutting forces, making it ideal for precision finishing, light cutting.
With an inscribed circle of 6.35 mm (1/4"), thickness of 1.59 mm (1/16"), and a corner radius of 0.4 mm, the TBMT060104DP provides precise dimensional control and consistent surface finishes down to Ra 0.6–1.2 µm. The specialized Double-Sided Positive (DP) chipbreaker geometry guarantees Superior chip evacuation across the recommended parameter range.

Chipbreaker Profile
The Double-Sided Positive (DP) chipbreaker is optimized for precision finishing, light cutting. Its unique land width and groove geometry ensure reliable chip formation and evacuation at the specified feed rates.
| Parameter | Double-Sided Positive (DP) |
|---|---|
| Application Category | Finishing |
| Recommended Feed (fn) | 0.05–0.15 mm/rev |
| Depth of Cut (ap) | 0.1–1.0 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: Superior chip evacuation 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 1.0 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 | 150–250 | 0.08–0.15 | 0.2–1.0 |
| Alloy Steel | 135–225 | 0.08–0.15 | 0.2–1.0 |
| Stainless Steel | 120–200 | 0.08–0.12 | 0.2–0.8 |
| Cast Steel | 100–180 | 0.08–0.15 | 0.2–1.0 |
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 TBMT060104DP is compatible with the following ISO toolholder families:
| Holder Family | Application |
|---|---|
| STFCR/L, STGCR/L, STWCR/L (external); 60° triangular 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.
