Product Overview
The Kyocera SGS 29/64 SGS30059 is a solid-carbide 4-flute, ball nose end mill from the Kyocera SGS precision milling program. The 29/64″ (11.509 mm) cutting diameter with a 0.22656″ (5.755 mm) ball radius makes it the tool of choice for 3D contouring, die & mold finishing, fillet work and surface machining on CNC machining centers and high-speed spindles.
The TA (TiAlN) coating provides a hard, heat-resistant surface (≈3,300 HV) that protects the ball tip from abrasive wear, delivering extended tool life and consistent surface finishes in tool steels, stainless alloys and hardened materials.

Chipbreaker Profile
On a ball nose mill, chip control comes from the flute and gash geometry:
- Deep, polished flute gullets evacuate fine finishing chips before they can mark the workpiece surface.
- 30° helix shears material progressively along the ball 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 |
| Engraving / V-Carving | ★★★★☆ | Use minimum quantity lubrication |
| Rest Milling / Corner Cleanup | ★★★★☆ | Reference previous larger tool's corner radius |
| Full Slotting | ★★☆☆☆ | Not recommended — use square-end variant |
Recommended Cutting Conditions
| Workpiece Material | Cutting Speed | Spindle Speed | Feed per Tooth | Feed Rate (4FL) |
|---|---|---|---|---|
| Aluminum / Brass / Copper | 300 SFM | 2,500 RPM | 0.0027"/tooth | 27.2 IPM |
| Mild / Low-Carbon Steel | 140 SFM | 1,200 RPM | 0.0027"/tooth | 13.1 IPM |
| Alloy / Tool Steel (≤35 HRC) | 110 SFM | 900 RPM | 0.0027"/tooth | 9.8 IPM |
| Stainless Steel (304/316) | 90 SFM | 800 RPM | 0.0027"/tooth | 8.7 IPM |
| Titanium Alloys | 60 SFM | 500 RPM | 0.0027"/tooth | 5.4 IPM |
| Hardened Steel (45–55 HRC) | 55 SFM | 500 RPM | 0.0027"/tooth | 5.4 IPM |
| Hardened Steel (55–62 HRC) | 40 SFM | 300 RPM | 0.0027"/tooth | 3.3 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.
- Use the shortest possible gauge length; small-diameter ball tips are fragile under side load.
- Program constant-chip-load toolpaths with ≤10% stepover for best surface finish.
- Avoid dwelling at the bottom of a cut; keep the tool moving to prevent tip rubbing.
- 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 |
|---|---|---|
| ER Collet Chuck | ER16 / ER20 collet, 1/2" bore | Best all-round choice for ball nose work |
| Shrink-Fit Holder | 1/2" bore | Maximum rigidity & ≤3 µm runout for finishing |
| Precision Milling Chuck | 1/2" capacity | Good for general machining centers |
| Hydraulic Chuck | 1/2" bore | Excellent vibration damping for fine finishes |
| Spindle Interface | HSK-E32/E40, BT30/40, CAT40 or straight-shank adapters | High-speed spindles preferred |
