1. Product Overview
The Kyocera LOMU150508ER-GH PR1825 TLT00082 is a high-performance indexable milling insert from Kyocera (Japan) for CNC machining centers. The LOMU geometry family (Rectangular 90°, clearance) delivers low cutting resistance with strong edge security, enabling high table feeds at consistent tool life. Precision-sintered and edge-inspected under ISO 9001 control, each insert seats with pocket-level repeatability for balanced multi-edge cutting.
Grade PR1825 is a Kyocera PVD milling grade with MEGACOAT NANO, rated at HV 3,400 surface hardness and oxidation stability to 1,100°C. In its P20–P35 / M20–P35 window it is built for general steel turning with excellent chipping resistance. Recommended workpiece groups: Carbon Steel, Alloy Steel, Stainless Steel.
On steel, program this insert around Vc 128–184 m/min with fz 0.072–0.156 mm/tooth; on a Ø63 mm × 6-tooth cutter that is roughly 808 RPM and 582 mm/min table feed. For stainless and HRSA use the dedicated parameter rows in Section 11 with reduced fz and continuous coolant.

11. RPM & Feed-Rate Examples by Cutter Diameter
| Cutter Body (example) | RPM @ Vc 160 m/min | Table Feed vf (mm/min) | Feed per Rev (mm) |
|---|---|---|---|
| Ø25 mm × 3T | 2,037 | 733 | 0.36 |
| Ø32 mm × 4T | 1,591 | 763 | 0.48 |
| Ø40 mm × 4T | 1,273 | 611 | 0.48 |
| Ø50 mm × 5T | 1,018 | 610 | 0.6 |
| Ø63 mm × 6T | 808 | 581 | 0.72 |

Formula: vf = fz × z × n = 0.12 × z × n. Values use the PVD-class steel parameters of this insert's grade; scale with the material factors in the cutting-condition table above.
12. Cutting Conditions — by Operation
| Operation | fz factor | ae (radial) | ap (axial) |
|---|---|---|---|
| Finishing (Ra 0.8–1.6 µm) | × 0.5–0.7 | 0.3–0.5 × Dc | 0.2–1.0 mm |
| Medium | × 1.0 | 0.5–0.7 × Dc | 1.0–3.0 mm |
| Roughing | × 1.2–1.5 | 0.6–0.8 × Dc | 2.0–5.0 mm |
Note: fz values are per-tooth. Program feed vf = fz × z × n. For thin-wall or low-rigidity setups reduce ae before reducing fz.
13. Wear Limits & Edge Management
| Criterion | Limit | Action |
|---|---|---|
| Flank wear VB | 0.30 mm | Index insert |
| Chipping | Micro-fractures at edge | Tougher grade / reduce fz |
| Cratering | 0.10 mm depth | Reduce Vc; improve coolant |
14. Cutter Body Compatibility
| Cutter Body Requirement | Specification |
|---|---|
| Seat accuracy | Pocket runout ≤ 0.02 mm; seat flatness ≤ 0.01 mm |
| Clamping | Torx screw, torque per size (1.2–3.5 Nm); replace screw when worn |
| Cutter runout | Total indicator runout ≤ 0.03 mm for finishing |
| Insert arrangement | Uniform pitch; distribute wear evenly around the cutter |
| Compatibility | Match insert size & thickness to the cutter pocket designation |
15. Troubleshooting Guide
| Problem | Cause | Solution |
|---|---|---|
| Edge chipping at exit | Exit burr impact | Reduce fz at exit; use climb milling; tougher grade |
| Cutter vibration | Long overhang / low rigidity | Shorten overhang; reduce ae; increase fz per tooth |
| Rapid flank wear | Vc too high | Reduce Vc 10–15%; check grade vs material |
| Built-up edge | Vc too low / sticky material | Increase Vc; sharper geometry; improve coolant |
| Poor flatness | Cutter runout | Check insert seating & screw torque; re-indicate |
16. Operating Guidelines
- Clean pockets before mounting; verify full seat contact
- Tighten Torx screws with a calibrated torque wrench
- Prefer climb milling for finishing; conventional for heavy scale or interruptions
- Use air blast or MQL for cast iron; emulsion for steel & stainless
- Index all inserts at consistent wear to keep the cutter balanced
- Avoid re-cutting chips in pocket milling — use air blast to clear the cavity

20. Frequently Asked Questions
Q: Which cutter bodies accept the LOMU150508ER-GH?
A: Any Kyocera or ISO cutter whose pocket designation matches this insert's size and thickness — see Section 14 requirements and match the seat exactly.
Q: What feed per tooth should I start with on LOMU150508ER-GH?
A: Start at fz ≈ 0.096 mm/tooth on steel and adjust within the 0.072–0.156 mm/tooth window per material.
Q: Can the LOMU150508ER-GH run dry?
A: On cast iron yes (air blast); on steel and stainless use emulsion or MQL — see the coolant column in Section 11.
Q: How do I calculate table feed for the LOMU150508ER-GH?
A: vf = fz × z × n. The worked examples in Section 12 cover Ø25–Ø125 cutters at this grade's steel parameters.
Q: When do I index the LOMU150508ER-GH?
A: At VB = 0.30 mm flank wear, or immediately if edge chipping appears — index all pockets together for balanced cutting.
