Kyocera 4,0 ENDMILL 4FL SQ SGS43103
1. Product Overview
The Kyocera 4,0 ENDMILL 4FL SQ SGS43103 is a solid-carbide 4-flute square-end endmill for CNC milling. It delivers stable side milling, slotting and pocketing with high material removal rates in steels, stainless steels and cast iron.
2. ISO Designation Breakdown
| Segment | Interpretation |
|---|---|
| SGS | Kyocera solid-carbide endmill family |
| 4 | 4-flute geometry series |
| 3 | Nominal diameter group |
| 103 | Square-end configuration / version code |
3. Engineering Dimensions & Geometry
| Parameter | Value |
|---|---|
| Nominal cutting diameter | 4,0 mm |
| Flute count | 4 |
| Nose geometry | Square end (corner radius = 0 mm) |
| Shank diameter | 4,0 mm |
| Helix angle | 30° |
| Overall length | Per manufacturer datasheet |
| Tolerance class | h6 |
4. Grade Details & Characteristics
- Substrate: ultra-fine-grain cemented carbide
- Coating: advanced AlTiN heat-resistant layer
- Hardness: ~92 HRA
- Edge preparation: micro-honed with polished flutes
- Max working temperature: ~900°C
5. Grade Comparison Matrix
| Grade | Speed | Wear resistance | Heat resistance | Primary materials |
|---|---|---|---|---|
| HSS-Co | Low | Moderate | Low | General steels |
| Uncoated carbide | Medium | Moderate | Low | Non-ferrous, cast iron |
| TiN-coated carbide | Medium | Good | Moderate | Steel, aluminium |
| AlTiN carbide (this tool) | High | Excellent | High | Steel, stainless, titanium |
6. Chipbreaker Profile
As a solid endmill, chip control is built into the flute geometry rather than a replaceable insert chipbreaker.
- Four continuous flutes for productive slotting and pocketing
- 30° helix angle for smooth side-cutting action
- Strong core and polished rake faces for chip flow
- Square-end profile for accurate 90° shoulders and floors
7. Recommended Applications & Materials
- Carbon and alloy steels up to ~45 HRC
- Austenitic and martensitic stainless steels
- Grey and nodular cast iron
- Titanium alloys at reduced speeds
- General machining, automotive, aerospace and mould/die components
8. Application Map by Operation
| Operation | Suitability |
|---|---|
| Slotting | Ideal |
| Pocketing | Ideal |
| Side milling / profiling | Recommended |
| Finishing | Recommended |
| 3D contouring | Not suitable |
9. Recommended Cutting Conditions
| Material | Vc (m/min) | fz (mm/tooth) | ap | ae | Coolant |
|---|---|---|---|---|---|
| Carbon steel | 100-150 | 0,025-0,040 | 1,0D | 0,2D | Emulsion |
| Stainless steel | 70-100 | 0,020-0,030 | 0,8D | 0,15D | Internal / flood |
| Cast iron | 90-130 | 0,030-0,050 | 1,2D | 0,25D | Air/oil mist |
| Titanium alloy | 40-70 | 0,015-0,025 | 0,5D | 0,10D | Flood |
10. Operating Guidelines
- Use the shortest possible overhang and a rigid toolholder.
- Keep tool run-out below 0,01 mm at the cutting edge.
- Avoid direct plunging; use ramp or helical entry where possible.
- Reduce speeds by 20-30% for unstable fixtures or long overhang.
- Ensure clean coolant delivery to prevent chip re-cutting.
11. Toolholder Compatibility
- ER20 precision collet for 4 mm shank
- Shrink-fit or hydraulic chuck with G2.5 balance
- Hydro-chuck for high-speed finishing
- Minimum clamping length = 2,5 x shank diameter
