1. Product Overview
The Kyocera 6 APR 3FL SGE34132-UN is a Kyocera solid carbide endmill, Ø6 mm, 3-flute, from the APR long-reach / rib processing series with square geometry and a 40° helix. A PVD TiAlN-class (MEGACOAT) nano-multilayer coating on an ultra-fine 0.4–0.6 µm carbide substrate delivers high-speed milling capability with long, predictable tool life across steels, stainless, cast iron and high-temp alloys.
Worked example on S45C steel at Vc 100 m/min: Ø6 mm runs ≈ 5,305 RPM with table feed ≈ 1,114 mm/min (fz 0.07 × 3 flutes). With ≈ 15 mm flute length and ≈ 55 mm overall length on a Ø6 mm h6 shank, maximum side-milling engagement is ap ≈ 15 mm × ae ≈ 0.6 mm for finishing, or ae up to 2.4 mm in adaptive roughing strategies. Clamp with runout ≤ 5 µm TIR and at least 2.5×D clamping length.

10. Recommended Cutting Conditions
| Workpiece Material | Vc (m/min) | fz (mm/t) | RPM | vf (mm/min) | ap (mm) | ae (mm) |
|---|---|---|---|---|---|---|
| Carbon Steel (S45C/C45) | 100 | 0.070 | 5,305 | 1,114 | 3.0 | 0.6 |

Programming note: vf = fz × z × n. For long overhang (>4×D) reduce Vc 20% and fz 25%. Climb milling recommended for finishing.
11. Toolpath Strategy Guide
| Strategy | ae (radial) | ap (axial) | When to Use |
|---|---|---|---|
| Finishing pass | 0.18–0.48 mm | up to 15 mm | Final walls, Ra ≤ 0.8 µm |
| Adaptive / dynamic roughing | 0.3–0.9 mm | 3.0–6 mm | High MRR with constant engagement |
| Conventional roughing | 2.4 mm | 3.0 mm | Rigid setups, open features |
| Full slotting | 6 mm | 1.5–3.0 mm | Only with reduced fz (−15%) |
12. Toolholding & Setup
| Holder Type | Runout | Recommendation |
|---|---|---|
| Shrink-fit | ≤ 3 µm | Best for high-speed finishing |
| Hydraulic chuck | ≤ 3 µm | Excellent damping — best all-round |
| High-precision ER collet | ≤ 5 µm | Good general use |
| Side-lock / Weldon | ≤ 10 µm | Roughing only |
| Milling chuck | ≤ 10 µm | Heavy roughing |
13. Wear Limits & Tool Life
| Criterion | Limit | Action |
|---|---|---|
| Flank wear | 0.15 mm (finishing) / 0.25 mm (roughing) | Replace or regrind |
| Corner chipping | Visible micro-chips | Check runout; reduce fz |
| Coating wear | Substrate visible | Tool at end of life |
| Regrinding | 2–3× possible | Use OEM-class regrind to restore geometry |
14. Coolant Strategy
| Material | Coolant |
|---|---|
| Steel / stainless | Flood emulsion 6–10% or MQL |
| Cast iron | Dry / air blast |
| Aluminum | Flood emulsion / alcohol-based MQL |
| Titanium / HRSA | High-pressure coolant ≥ 20 bar |
| Hardened steel | Oil / MQL; avoid thermal shock |
15. Troubleshooting Guide
| Problem | Cause | Solution |
|---|---|---|
| Edge chipping | Runout / vibration | Check runout ≤ 5 µm; reduce fz |
| Rapid wear | Vc too high | Reduce Vc 10–20% |
| Poor finish | Worn edge / deflection | Replace tool; reduce ae |
| Chatter | Overhang / wrong parameters | Shorten overhang; vary RPM ±10% |
| Chip welding (aluminum) | Dry cutting / low feed | MQL + increase fz; polished flute helps |
16. Operating Guidelines
- Verify runout ≤ 5 µm TIR before use
- Minimum clamping length 2.5×D in the holder
- Run-in at 80% parameters for the first pass
- Use ramp or helical entry — avoid straight plunging
- Keep chips clear of the cut zone with air blast / coolant
- Store in the protective tube; never let tools contact each other

20. Frequently Asked Questions
Q: What RPM should I run the Ø6 mm 3FL at?
A: On steel at Vc 100 m/min: ≈ 5,305 RPM; scale linearly with the material Vc column in Section 10.
Q: Can the Ø6 mm endmill slot?
A: Yes — at full 6 mm slot width reduce fz by 15% and use the 2/3-flute chip-evacuation advantage; ramp or helical entry only.
Q: What holder runout is acceptable?
A: ≤ 5 µm TIR — beyond that, one flute does the work and tool life collapses.
Q: What surface finish can I expect?
A: With ae = 0.3 mm finishing passes and climb milling: Ra 0.4–0.8 µm on steel.
Q: How do I entry-cut safely?
A: Use ramp (3–5°) or helical interpolation entry; avoid straight plunging except with 2FL center-cutting geometry at reduced feed.
