1. Product Overview
The Kyocera 11IR100ISO-TF PR1535 TLC18426D is a Kyocera indexable threading insert for CNC single-point thread turning. Internal right hand geometry cuts ISO Metric 60° threads to ISO 68-1 / ISO 965 with pitch 1.00 mm (≈ 25.4 TPI). The full profile (crest-finishing) design finishes thread crests in a single pass for full-spec thread form and gauge-ready results.
Grade PR1535 (MEGACOAT NANO PLUS) is a PVD threading grade at HV 3,300 surface hardness and 1,050°C heat stability, keeping thread flanks sharp and wear-resistant for carbon steel, alloy steel, stainless steel, cast iron, heat-resistant alloy. Ground flank geometry holds ±15 arcmin flank-angle accuracy.
Threading is pass-schedule critical: for the 1.00 mm (≈ 25.4 TPI) pitch of this insert, the total radial thread depth is ≈ 0.613 mm, typically cut in 6–12 passes with decreasing infeed — a complete worked schedule is given in Section 11. Constant surface speed with an RPM cap and flood coolant at the thread are mandatory for flank finish and tool life.

10. Recommended Cutting Conditions
| Workpiece Material | Vc (m/min) | No. of Passes (typ.) | Radial Infeed per Pass (mm) | Coolant |
|---|---|---|---|---|
| Carbon Steel (S45C/C45, HB 180) | 99–153 | 6–12 | 0.25 → 0.02 (decreasing) | Wet, high volume |
| Alloy Steel (SCM440/4140, HB 280) | 99–153 | 6–12 | 0.25 → 0.02 (decreasing) | Wet, high volume |
| Stainless Steel (SUS304/1.4301) | 77–119 | 8–14 | 0.25 → 0.02 (decreasing) | Wet, high volume |
| Gray Cast Iron (FC250/GG25) | 88–136 | 6–12 | 0.25 → 0.02 (decreasing) | Wet, high volume |
| Nodular Cast Iron (FCD450) | 88–136 | 6–12 | 0.25 → 0.02 (decreasing) | Wet, high volume |
| Heat-Resistant Alloy (Inconel 718) | 24–38 | 8–14 | 0.25 → 0.02 (decreasing) | Wet, high volume |
| Titanium Alloy (Ti-6Al-4V) | 24–38 | 8–14 | 0.25 → 0.02 (decreasing) | Wet, high volume |
11. Infeed Strategy
| Infeed Method | Chip Load Distribution | Recommendation |
|---|---|---|
| Radial infeed | Equal on both flanks | Standard for pitches ≤ 1.5 mm |
| Flank infeed 27–29° | Load on leading flank | Recommended for pitches > 1.5 mm — better chip control & finish |
| Alternating flank | Alternates flanks | Large pitches & difficult materials; evens flank wear |
12. Worked Pass Schedule for This Pitch
| Pass No. | Radial Infeed (mm) | Cumulative Depth (mm) | Stage |
|---|---|---|---|
| 1 | 0.215 | 0.215 | Roughing |
| 2 | 0.153 | 0.368 | Roughing |
| 3 | 0.115 | 0.483 | Roughing |
| 4 | 0.077 | 0.560 | Roughing |
| 5 | 0.038 | 0.598 | Finishing / spring |
| 6 | 0.015 | 0.613 | Finishing / spring |
Thread depth: ISO 60° external depth ≈ 0.6134 × P = 0.613 mm for P = 1 mm. Decreasing infeed keeps chip section constant and flanks clean.
13. Wear Limits
| Criterion | Limit | Action |
|---|---|---|
| Flank wear | 0.15 mm | Index insert — thread accuracy is wear-critical |
| Nose chipping | Any | Replace; check infeed & rigidity |
| Thread gauge failure | Worn or mis-set insert | Compensate offset or index insert |
14. Compatible Holders
| Compatible Holder | Type | Notes |
|---|---|---|
| KTNR/L 1140-11 | External threading holder | Laydown pocket, shim-protected seat |
| S11-KTNR/L 11 | Internal threading bar | Steel or carbide shank |
| Screw-on holders | Compact holders | Small pitches & Swiss machines |
15. Troubleshooting Guide
| Problem | Cause | Solution |
|---|---|---|
| Torn thread flanks | Built-up edge / low Vc | Increase Vc; ensure coolant; sharper grade |
| Flank chipping | Vibration / infeed too large | Reduce last-pass infeed to 0.02–0.05 mm; check rigidity |
| Wrong pitch diameter | Tool wear / wrong offset | Measure & compensate; index insert |
| Poor thread finish | Too few passes | Increase pass count; final spring pass at 0.02 mm |
| Chatter on long threads | Workpiece deflection | Use steady rest; reduce Vc; flank infeed |
16. Operating Guidelines
- Set center height precisely — threading is highly sensitive (±0.03 mm)
- Use constant surface speed with an RPM cap
- Always finish with a spring pass of 0.02 mm radial infeed
- Flood coolant directly at the thread — threading heat is concentrated
- Never re-cut a pass with a worn edge — gauge failure risk
- Index at the first sign of flank wear on gauge-critical threads

20. Frequently Asked Questions
Q: What thread does the 11IR100ISO-TF cut?
A: ISO Metric 60° (ISO 68-1 / ISO 965) at pitch 1.00 mm (≈ 25.4 TPI) — full profile (crest-finishing).
Q: How many passes do I need for the 11IR100ISO-TF?
A: Typically 6–12 passes; the full worked schedule for this pitch is in Section 11 (total depth ≈ 0.613 mm).
Q: Radial or flank infeed with the 11IR100ISO-TF?
A: Radial infeed is fine at this pitch; above 1.5 mm pitch use 27–29° flank infeed.
Q: Which holders fit the 11IR100ISO-TF?
A: KTNR/L-style laydown threading holders in size 11 — see Section 14.
Q: Why did my thread fail the gauge with the 11IR100ISO-TF?
A: Most often flank wear — threading inserts must be indexed at 0.15 mm VB, earlier than turning inserts. Verify offset after indexing.
