Product Overview
The Kyocera SGS 1/2 SGS30592 is a solid-carbide 2-flute, ball nose end mill from the Kyocera SGS finishing program. The 1/2″ (12.7 mm) cutting diameter with a 0.25″ (6.35 mm) ball radius is engineered for high-accuracy 3D contouring, die & mold finishing and surface machining.
The 2-flute layout maximizes chip space at the ball tip — the classic finishing configuration — while the TA (TiAlN) coating (≈3,300 HV) protects the radius from abrasive wear, delivering extended tool life and consistent finishes in tool steels, stainless alloys and hardened materials up to 62 HRC.

Chipbreaker Profile
Chip control on this 2-flute ball nose comes from its flute and gash geometry:
- Two extra-deep polished gullets give maximum chip-evacuation volume at the ball tip — critical on fine 3D finishing passes.
- 30° helix shears material progressively along the radius, minimizing chatter and tool marks.
- Center-cutting ball gash maintains cutting action at the tip center where surface speed approaches zero.
- TiAlN-coated flutes resist chip welding in die steels and stainless alloys.
Recommended Applications & Workpiece Materials
| Workpiece Material (ISO Class) | Suitability | Notes |
|---|---|---|
| ISO P — Carbon & alloy steels (≤45 HRC) | Excellent | 3D finishing & contouring |
| ISO M — Stainless steels (303/304/316) | Very Good | Light radial engagement, steady feed |
| ISO K — Cast irons | Very Good | Die/mold surfacing |
| ISO N — Aluminum & copper alloys | Good | Use air blast / MQL to avoid built-up edge |
| ISO S — Titanium & heat-resistant alloys | Good | Low SFM, rigid setup |
| ISO H — Hardened steels (45–62 HRC) | Excellent | Primary application — die/mold finishing |
Application Map by Operation
| Milling Operation | Suitability | Guideline |
|---|---|---|
| 3D Contouring / Surfacing | ★★★★★ | Stepover ≤ 5–10% of D for mirror-class finishes |
| Die & Mold Finishing | ★★★★★ | Tilt tool 10–15° to keep tip center out of cut |
| Fillet & Radius Milling | ★★★★★ | Match ball radius to part fillet |
| Rest Milling / Corner Cleanup | ★★★★☆ | Reference previous larger tool's corner radius |
| Engraving / V-Carving | ★★★★☆ | Use minimum quantity lubrication |
| Full Slotting | ★★☆☆☆ | Not recommended — use square-end variant |
Recommended Cutting Conditions
| Workpiece Material | Cutting Speed | Spindle Speed | Feed per Tooth | Feed Rate (2FL) |
|---|---|---|---|---|
| Aluminum / Brass / Copper | 300 SFM | 2,300 RPM | 0.0030"/tooth | 13.8 IPM |
| Mild / Low-Carbon Steel | 140 SFM | 1,100 RPM | 0.0030"/tooth | 6.6 IPM |
| Alloy / Tool Steel (≤35 HRC) | 110 SFM | 800 RPM | 0.0030"/tooth | 4.8 IPM |
| Stainless Steel (304/316) | 90 SFM | 700 RPM | 0.0030"/tooth | 4.2 IPM |
| Titanium Alloys | 60 SFM | 500 RPM | 0.0030"/tooth | 3.0 IPM |
| Hardened Steel (45–55 HRC) | 55 SFM | 400 RPM | 0.0030"/tooth | 2.4 IPM |
| Hardened Steel (55–62 HRC) | 40 SFM | 300 RPM | 0.0030"/tooth | 1.8 IPM |
Finishing values at ≤10% stepover; reduce feed 30% on steep-wall 3D surfaces.
Operating Guidelines
- Keep tool-holder runout below 0.0004" (10 µm) TIR — runout destroys ball-tip accuracy.
- Tilt the spindle/tool 10–15° on flat areas so the low-speed tip center never dwells in the cut.
- Program constant-chip-load toolpaths with ≤10% stepover for best surface finish.
- With only 2 cutting edges, keep feed per tooth steady — never dwell in the cut.
- Avoid thermal shock: in hardened steels run dry or with MQL rather than intermittent flood.
- Retire the tool at the first sign of tip wear — worn ball tips ruin surface finish before they break.
Toolholder Compatibility
| Holder System | Specification | Notes |
|---|---|---|
| Shrink-Fit Holder | 1/2" bore | Maximum rigidity & ≤3 µm runout — first choice for finishing |
| ER Collet Chuck | ER20 / ER32 collet, 1/2" bore | Best all-round choice |
| Hydraulic Chuck | 1/2" bore | Excellent vibration damping for fine finishes |
| Side-Lock (Weldon) Holder | 1/2" bore | Secure grip for heavier passes |
| Spindle Interface | HSK-E40/A63, BT40, CAT40 adapters | High-speed spindles preferred |
