Product Overview
The Kyocera SGS SGS30900 is a multi-piece solid-carbide ball nose end mill set from the Kyocera SGS milling program. Every tool is a 3-flute, TN (TiN) coated ball nose mill, covering the most-used fractional diameters for 3D contouring, die & mold finishing and surface machining.
The 3-flute layout opens deep chip gullets and suppresses harmonic chatter, while the TiN (Titanium Nitride) coating protects every ball radius in the set. All tools arrive in a fitted storage case that protects the delicate tips and keeps sizes organized at the machine.

| Relative Tool Life (in steel) | Up to 1.5× baseline | Up to 3× baseline | Baseline |
Chipbreaker Profile
Every ball nose tool in the set controls chips through its flute and gash geometry:
- Extra-deep polished gullets — fewer flutes means more room per flute, so chips clear before they mark the surface.
- 30° helix shears material progressively along the ball radius, minimizing chatter.
- Odd (3) flute count breaks up harmonic vibration for chatter-free finishes.
- Center-cutting ball gash maintains cutting action at the tip center.
Recommended Applications & Workpiece Materials
| Workpiece Material (ISO Class) | Suitability | Notes |
|---|---|---|
| ISO P — Carbon & alloy steels (≤35 HRC) | Excellent | Primary application |
| ISO M — Stainless steels (303/304/316) | Very Good | Light radial engagement, steady feed |
| ISO K — Cast irons | Very Good | General-purpose milling |
| Copper Alloys (brass, bronze) | Good | Light cuts, air blast |
| ISO N — Aluminum (wrought) | Fair | Possible; uncoated variant preferred |
| ISO H — Hardened steels (>45 HRC) | Not recommended | Use TiAlN-coated variant |
Application Map by Operation
| Milling Operation | Suitability | Guideline |
|---|---|---|
| 3D Contouring & Surfacing | ★★★★★ | Stepover ≤ 5–10% of D for mirror 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 | ★★★★☆ | Use minimum quantity lubrication |
| Rest Milling / Corner Cleanup | ★★★★☆ | Pick set size to match corner radius |
| Full Slotting | ★★☆☆☆ | Not recommended — use square-end set |
Recommended Cutting Conditions
| Workpiece Material | Cutting Speed | Feed per Tooth (per tool size) |
|---|---|---|
| Mild / Low-Carbon Steel | 110 SFM | 0.6% of tool diameter |
| Alloy Steel (≤35 HRC) | 90 SFM | 0.6% of tool diameter |
| Stainless Steel (304/316) | 75 SFM | 0.6% of tool diameter |
| Cast Iron | 120 SFM | 0.6% of tool diameter |
| Brass / Bronze | 200 SFM | 0.6% of tool diameter |
RPM = SFM × 3.82 ÷ tool diameter. Finishing values at ≤10% stepover.
Operating Guidelines
- Keep tool-holder runout below 0.0004" (10 µm) TIR on every size.
- Tilt the tool 10–15° on flat areas so the low-speed tip center never dwells in the cut.
- TiN is a general-purpose coating — use flood coolant or MQL in steels for best life.
- Return each tool to its fitted slot after use — ball tips chip easily when stored loose.
- Replenish individual sizes from the same TN-coated 3FL series as they wear.
Toolholder Compatibility
| Holder System | Specification | Notes |
|---|---|---|
| Shrink-Fit Holder | Sized to shank | ≤3 µm runout — first choice for finishing |
| ER Collet Chuck | ER16 / ER20 collets per shank size | Best all-round choice |
| Hydraulic Chuck | Sized to shank | Vibration damping for fine finishes |
| Spindle Interface | HSK-E40/A63, BT40, CAT40 adapters | High-speed spindles preferred |
