Product Overview
The TNMG160412PP is a premium 60° Trigon Insert (Double-Sided) manufactured by Kyocera under grade CA125P. Engineered for Precision Finishing to Light Roughing, this indexable carbide insert delivers exceptional dimensional accuracy, superior surface finish, and extended tool life in demanding CNC turning operations. The insert features a 1.2 mm and is optimized for machining Carbon steel, alloy steel, stainless steel, and cast iron.
ISO Designation Breakdown
| Parameter | Specification |
|---|---|
| ISO Code | TNMG160412PP |
| Insert Shape | 60° Trigon Insert (Double-Sided) (T) |
| Clearance Angle | 0° (N) |
| Tolerance Class | Medium (M) |
| Hole / Fixing | With cylindrical hole and countersink (G) |
| Inscribed Circle | MG mm |
| Insert Thickness | 16 mm |
| Nose Radius | 1.2 mm |
| Chipbreaker | PP — Precision Positive |
Engineering Dimensions & Geometry
The TNMG160412PP is precision-ground to tight tolerances ensuring consistent seating in standard toolholders. Key dimensional data includes an inscribed circle diameter of MG mm, overall thickness of 16 mm, and a corner nose radius of 1.2 mm. The positive rake for low cutting forces and heat generation. These geometric attributes minimize cutting vibration and promote stable chip formation across the recommended parameter window.
Grade Details — Key Grade Characteristics
CA125P PVD Coated Carbide is a high-performance grade featuring:
- Excellent balance of wear resistance and fracture toughness for general turning
- Superior resistance to built-up edge (BUE) in steel and stainless steel
- Stable performance in continuous and light-to-medium interrupted cuts
- Good thermal shock resistance for both dry and wet machining
- Optimized for medium to high cutting speeds in general machining
- Enhanced crater wear resistance compared to uncoated grades
The CA125P substrate is paired with a PVD (Physical Vapor Deposition) Multi-layer Coating to create a thermally stable cutting edge capable of maintaining hardness at elevated temperatures generated during high-speed steel machining.
Grade Comparison Matrix
| Property | CA125P | CA115P | CA130 |
|---|---|---|---|
| Wear Resistance | High | High | Medium |
| Toughness | High | Medium-High | Very High |
| Coating | PVD Multi-layer | PVD Multi-layer | PVD |
| Primary Use | General / Semi-Rough | General / Semi-Finish | Roughing |
| Speed Range | Medium-High | Medium-High | Low-Medium |
CA125P offers improved toughness over CA115P and is better suited for semi-roughing to medium finishing. It sits between CA120 (finishing) and CA130 (roughing) in the Kyocera grade spectrum.
Chipbreaker Profile
PP — Precision Positive
Positive rake with precision-ground edges for minimal burr and superior surface finish. Smooth chip evacuation and reduced built-up edge tendency for high-accuracy work.
Key Chipbreaker Attributes:
- Positive rake for low cutting forces and heat generation
- Robust chip breaking across broad parameter ranges
- Optimized land width for edge strength and finish quality balance
- Precision-ground peripheral edges for accurate repeatability
Recommended Applications & Workpiece Materials
The TNMG160412PP CA125P is recommended for the following materials and application types:
- Carbon Steel: Continuous and semi-interrupted turning (C45, C60, 1045, 1060)
- Alloy Steel: Medium alloy steels up to 40 HRC (4140, 4340, 16MnCr5)
- Stainless Steel: Austenitic and martensitic grades (304, 316, 410, 420)
- Cast Iron: Gray cast iron and nodular cast iron (GG25, GGG40)
- Forged Components: Scale-covered surfaces with light interruption
Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| External Turning | ★★★★★ | Primary application; excellent chip control |
| Internal Turning / Boring | ★★★★☆ | Use with appropriate boring bars |
| Facing | ★★★★★ | Smooth entry and exit cuts |
| Profiling / Contouring | ★★★★☆ | 1.2 mm radius ideal for smooth profiles |
| Grooving | ★★☆☆☆ | Not recommended; use dedicated grooving inserts |
| Parting / Cut-off | ★☆☆☆☆ | Not designed for parting operations |
Recommended Cutting Conditions
Medium speeds, depths 0.2–2.5 mm, feeds 0.08–0.30 mm/rev.
| Workpiece Material | Cutting Speed (m/min) | Feed (mm/rev) | Depth of Cut (mm) |
|---|---|---|---|
| Low-Carbon Steel | 200–280 | 0.10–0.30 | 0.5–3.0 |
| Medium-Carbon Steel | 180–250 | 0.10–0.30 | 0.5–3.0 |
| Alloy Steel (≤30 HRC) | 150–220 | 0.10–0.28 | 0.5–2.5 |
| Stainless Steel (Austenitic) | 120–180 | 0.08–0.25 | 0.5–2.5 |
| Gray Cast Iron | 150–200 | 0.10–0.30 | 0.5–3.0 |
| Nodular Cast Iron | 120–170 | 0.10–0.28 | 0.5–2.5 |
Operating Guidelines
- Always verify insert seating and clamping force before starting the spindle.
- Use coolant or cutting fluid for materials prone to work-hardening (e.g., austenitic stainless steels).
- Ensure rigid tooling setup to minimize vibration; use anti-vibration boring bars for deep internal operations.
- Monitor flank wear (VB) and replace inserts when wear reaches 0.3 mm for roughing or 0.15 mm for finishing.
- Index the insert to a fresh edge if chipping, built-up edge, or discoloration is observed.
- For best surface finish, use the highest cutting speed within the recommended range and the lowest stable feed rate.
Toolholder Compatibility
The TNMG160412PP is compatible with standard ISO toolholders designed for 60° Trigon Insert (Double-Sided) inserts with a MG mm inscribed circle and 16 mm thickness. Recommended toolholder series include:
- External Turning: Standard lever-lock or screw-clamp holders (e.g., MTJNR, MTQNR for T-inserts)
- Internal Turning: Boring bars with 93° or 107° approach angles (e.g., S20R-MTJNR, S25R-MTJNR)
- Clamp System: Ensure holder chip groove matches insert thickness (16 mm) for proper seating
- Coolant Delivery: High-pressure coolant toolholders recommended for chip evacuation in blind-hole boring
