Product Overview
The Kyocera SGS 1/2 SGS30180 is a solid-carbide 4-flute, square-end end mill with a Weldon-flat (WF) shank, from the Kyocera SGS general-purpose milling program. The 1/2″ (12.7 mm) cutting diameter is built for production slotting, side milling and pocketing where positive, slip-free tool clamping is essential.
The ground Weldon flat locks the tool against rotation and pull-out in side-lock holders — the safest clamping method for heavy cuts — while the uncoated, diamond-polished micro-grain carbide cutting edges stay razor-sharp and free-cutting in aluminum, brass, copper and other non-ferrous materials.

|---|---|---|---|
| Wear Resistance | ★★★★☆ | ★★★★★ | ★★★☆☆ |
| Edge Sharpness | ★★★★★ | ★★★★☆ | ★★★☆☆ |
| Heat Resistance | ★★★☆☆ | ★★★★★ | ★★★☆☆ |

| Steels & Stainless | Fair | Excellent | Fair |
| 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 in slots and pockets.
- 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 | Heavy slotting & profiling with WF grip |
| Plastics / Composites (Acrylic, PEEK, G10) | Excellent | Burr-free trimming |
| ISO P — Low-carbon steels | Good | Light-to-moderate radial engagement |
| ISO K — Cast irons | Fair | Occasional light duty |
| 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 |
|---|---|---|
| Full Slotting | ★★★★★ | WF shank allows full 0.5×D (0.25") slots without pull-out risk |
| Side Milling / Profiling | ★★★★★ | Radial WOC 10–30% of D for best finish |
| Pocketing | ★★★★☆ | Ramping entry at 3–5° |
| Facing / Surfacing | ★★★★☆ | Stepover ≤ 60% of D |
| Plunging | ★★★☆☆ | Center-cutting; peck in 0.5×D steps |
| 3D Contouring | ★★★☆☆ | Square end — use ball nose variant for 3D work |
Recommended Cutting Conditions
| Workpiece Material | Cutting Speed | Spindle Speed | Feed per Tooth | Feed Rate (4FL) |
|---|---|---|---|---|
| Aluminum / Brass / Copper | 300 SFM | 2,300 RPM | 0.0040"/tooth | 36.8 IPM |
| Plastics / Composites | 400 SFM | 3,100 RPM | 0.0040"/tooth | 49.6 IPM |
| Mild / Low-Carbon Steel | 110 SFM | 800 RPM | 0.0040"/tooth | 12.8 IPM |
| Cast Iron | 130 SFM | 1,000 RPM | 0.0040"/tooth | 16.0 IPM |
| Stainless Steel (304/316) | 75 SFM | 600 RPM | 0.0040"/tooth | 9.6 IPM |
Starting recommendations for rigid setups; adjust ±20% for machine stiffness and holder condition.
Operating Guidelines
- Seat the tool so the set screw lands squarely on the Weldon flat — never on the round shank.
- Torque side-lock screws to the holder maker's spec; re-check after the first heavy cut.
- Use the shortest possible gauge length for maximum rigidity.
- Climb mill whenever machine rigidity allows for better finish and tool life.
- Start at 70–80% of recommended feed and speed, then optimize upward in 10% steps.
- Inspect edges regularly; index out at uniform flank wear of 0.008–0.012".
Toolholder Compatibility
| Holder System | Specification | Notes |
|---|---|---|
| Side-Lock (Weldon) End Mill Holder | 1/2" bore | Primary choice — matches the WF flat |
| ER Collet Chuck | ER20 / ER32 collet, 1/2" bore | Fully compatible; flat does not affect collets |
| Shrink-Fit Holder | 1/2" bore | ≤3 µm runout for finishing |
| Hydraulic Chuck | 1/2" bore | Vibration damping for fine finishes |
| Spindle Interface | BT40, CAT40/50, HSK-A63 adapters | Match to machine spindle |
