1. Product Overview
The Kyocera SGS40121 is a 3.0 mm solid carbide square end mill with four flutes, engineered for high-precision CNC milling. It offers balanced cutting forces, stable chip evacuation and long tool life in slotting, profiling and shoulder-milling operations.
2. ISO Designation Breakdown
| Code Segment | Meaning |
|---|---|
| SGS | Solid carbide end-mill series |
| 4 | 4-flute construction |
| 0 | Standard flute / overall length ratio |
| 1 | 3.0 mm nominal cutting diameter |
| 21 | Square-end geometry variant |
3. Engineering Dimensions & Geometry
| Parameter | Value |
|---|---|
| Cutting diameter (D) | 3.0 mm |
| Number of flutes | 4 |
| Corner radius | Square (0° corner) |
| Helix angle | 30° – 35° (standard) |
| Shank diameter | 3.0 mm |
| Application type | General to semi-finishing |
4. Grade Details & Characteristics
- Substrate: Micro-grain tungsten carbide for high hardness and wear resistance.
- Coating: Advanced PVD / TiAlN-based coating reduces heat and extends tool life.
- Edge preparation: Controlled hone for edge strength and stable finishes.
- Hardness range: Suitable for materials up to ~50 HRC in standard applications.
5. Grade Comparison Matrix
| Grade/Series | Coating | Best For | Max HRC |
|---|---|---|---|
| SGS (this tool) | TiAlN / PVD | Steel, stainless, cast iron | ~50 HRC |
| SGS Hard | AlTiSiN | Hardened steels, tool steel | ~55–60 HRC |
| Alu-series | Uncoated / DLC | Aluminium, non-ferrous | – |
6. Chipbreaker Profile
Four-flute geometry with a medium-to-high helix and open gash design. The flute profile supports fast chip evacuation in narrow slots and maintains stable cutting in semi-finishing passes. The square cutting edge enables 90° shoulders and clean corners.
7. Recommended Applications & Materials
- Carbon and alloy steels (ISO P-group)
- Stainless steels, austenitic and martensitic (ISO M-group)
- Cast iron and nodular cast iron (ISO K-group)
- Brass and bronze with reduced speeds
- General engineering, mould and die finishing
8. Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Slotting | Excellent | Use ae = Dc, moderate ap |
| Profiling / side milling | Excellent | High ae possible, stable finishes |
| Shoulder milling | Excellent | Square edge gives 90° walls |
| Pocketing | Good | Ramping entry recommended |
| Plunging | Limited | Not a centre-cutting plunge tool |
9. Recommended Cutting Conditions
| Material | vc (m/min) | fz (mm/tooth) | ap (mm) |
|---|---|---|---|
| Carbon steel | 80 – 120 | 0.02 – 0.05 | 1 × D |
| Stainless steel | 50 – 80 | 0.015 – 0.04 | 0.8 × D |
| Cast iron | 70 – 100 | 0.02 – 0.05 | 1 × D |
| Brass / bronze | 100 – 150 | 0.02 – 0.06 | 1 × D |
10. Operating Guidelines
- Secure the tool in a precision collet or shrink-fit holder with minimal run-out.
- Prefer ramp or helical entry into pockets; avoid direct plunging unless centre-cutting.
- Use adequate coolant or air blast to clear chips and prevent re-cutting.
- Reduce speeds by 15–20% for stainless or hard materials.
- Verify spindle RPM and feed rate with the manufacturer calculator for best results.
11. Toolholder Compatibility
Compatible with ER11/ER16 collet chucks, hydraulic chucks, milling chucks and shrink-fit holders with a 3.0 mm clamping bore. Use ISO 30, 40 or 50 taper machining centres with rigid fixturing and balanced high-speed spindles.
