Product Overview
The Kyocera SGS 29/64 SGS30158 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 is purpose-built for 3D contouring, engraving and fine finishing on CNC machining centers and high-speed spindles.
The uncoated, diamond-polished micro-grain carbide surface keeps the cutting edge razor-sharp and free-cutting — ideal for aluminum, brass, copper, plastics and other non-ferrous materials where built-up edge must be avoided.

| Relative Tool Life | Baseline | Up to 3× baseline | 0.7× baseline |
Chipbreaker Profile
Chip control on this tool comes from its flute and gash geometry:
- Deep, polished flute gullets give chips maximum evacuation volume, preventing re-cutting and clogging.
- 30° helix lifts chips smoothly out of the cut while keeping cutting forces low and chatter-free.
- Center-cutting gash geometry allows plunging and ramping entries without a pilot hole.
- Fine edge preparation (≤5 µm) shears material cleanly, producing small, manageable chips even in gummy alloys.
Recommended Applications & Workpiece Materials
| Workpiece Material (ISO Class) | Suitability | Notes |
|---|---|---|
| ISO N — Aluminum, brass, copper, bronze | Excellent | High-speed finishing & contouring |
| Plastics / Composites (Acrylic, PEEK, G10) | Excellent | Burr-free trimming & engraving |
| Precious Metals (gold, silver, platinum) | Excellent | Jewelry & die work |
| ISO P — Low-carbon steels | Good | Light finishing passes |
| ISO M — Stainless steels | Fair | Finishing only, flood coolant |
| ISO H — Hardened steels | 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 |
| Engraving / V-Carving | ★★★★★ | Use minimum quantity lubrication |
| Fine Fillet & Radius Work | ★★★★★ | Match ball radius to part fillet |
| Die & Mold Detail Finishing | ★★★★☆ | Tilt tool 10–15° off flat areas |
| Rest Milling | ★★★★☆ | Reference previous 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 |
| Plastics / Composites | 400 SFM | 3,400 RPM | 0.0027"/tooth | 37.0 IPM |
| Precious Metals | 250 SFM | 2,100 RPM | 0.0027"/tooth | 22.8 IPM |
| Mild / Low-Carbon Steel | 100 SFM | 800 RPM | 0.0027"/tooth | 8.7 IPM |
| Stainless Steel (304/316) | 70 SFM | 600 RPM | 0.0027"/tooth | 6.5 IPM |
Starting recommendations for rigid setups; adjust ±20% for machine stiffness and holder runout.
Operating Guidelines
- Keep tool-holder runout below 0.0004" (10 µm) TIR — runout is the leading cause of premature edge failure.
- Use the shortest possible gauge length; never extend the tool beyond the flute length plus clearance.
- Climb mill whenever machine rigidity allows for better surface finish and tool life.
- Start at 70% of recommended feed and speed, then optimize upward in 10% steps.
- Use air blast or mist for non-ferrous work; avoid flood-coolant thermal shock on small tools.
- Retire the tool at the first sign of edge chipping or size drift.
Toolholder Compatibility
| Holder System | Specification | Notes |
|---|---|---|
| ER Collet Chuck | ER16 / ER20 collet, 1/2" bore | Best all-round choice for GP milling |
| Shrink-Fit Holder | 1/2" bore | ≤3 µm runout for finishing |
| Side-Lock (Weldon) End Mill Holder | 1/2" bore | Maximum grip for slotting |
| Hydraulic Chuck | 1/2" bore | Excellent vibration damping for fine finishes |
| Spindle Interface | BT40, CAT40, HSK-A63 or straight-shank adapters | Match to machine spindle |
