1. Product Overview
The Kyocera 5.0 mm 4-flute ball nose end mill (MPN SGS40138) is a solid carbide rotary cutter designed for precision CNC contouring and finishing. It delivers smooth 3D profiling, mold-and-die finishing and curved surface machining on carbon steel, alloy steel, stainless steel and cast iron.
2. ISO Designation Breakdown
| Code | Meaning |
|---|---|
| 5.0 | Nominal cutting diameter 5.0 mm |
| ENDMILL | Solid carbide end mill |
| 4FL | 4 flutes for stable finish milling |
| BN | Ball nose (R = 2.5 mm) end geometry |
| SGS40138 | Kyocera product / catalogue code |
3. Engineering Dimensions & Geometry
| Parameter | Value |
|---|---|
| Nominal cutting diameter | 5.0 mm |
| Shank diameter | 5.0 mm |
| Number of flutes | 4 |
| Nose radius | 2.5 mm (ball nose) |
| Helix angle | 30° (typical) |
| Overall length | Standard series; check datasheet |
4. Grade Details & Characteristics
This end mill uses a Kyocera micro-grain solid carbide substrate that balances hardness, toughness and edge stability. It is intended for general-purpose contouring and finishing of ferrous materials. Coating and exact grade details are tied to the product code; consult the factory datasheet for specific grade information.
5. Grade Comparison Matrix
| Grade type | Wear resistance | Heat resistance | Typical materials |
|---|---|---|---|
| Uncoated carbide | Medium | Low-Medium | Non-ferrous, soft steels |
| TiAlN / AlTiN coated | High | High | Hardened steel, stainless |
| DLC / TiAlSiN coated | Very high | Very high | High-speed / titanium alloys |
6. Chipbreaker Profile
The four-flute helical ball-nose geometry provides a strong core and controlled chip curl. Open chip pockets support efficient chip evacuation at medium-to-light chip loads, making the cutter well suited for 3D finishing, contouring and semi-finishing passes.
7. Recommended Applications & Materials
- 3D profiling, contouring and sculptured surfaces
- Mold and die finishing
- Finishing curved walls and fillets
- Carbon steel, alloy steel and stainless steel
- Cast iron and selected non-ferrous materials (with compatible grade/coating)
8. Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Roughing | Limited | Lower engagement; use larger cutter for heavy stock removal |
| Semi-finishing | Good | Balanced speed and feed |
| 3D finishing | Excellent | Fine stepover for smooth surface finish |
| Slotting | Not recommended | Ball profile is not designed for straight slots |
9. Recommended Cutting Conditions
| Workpiece material | Cutting speed Vc (m/min) | Feed per tooth fz (mm) |
|---|---|---|
| Carbon / low-alloy steel | 80 - 120 | 0.05 - 0.12 |
| Stainless steel | 60 - 100 | 0.05 - 0.10 |
| Cast iron | 100 - 160 | 0.08 - 0.15 |
| Aluminium / non-ferrous | 200 - 300 | 0.05 - 0.15 |
Start at the lower end of the range and increase once tool stability, surface finish and chip control are confirmed.
10. Operating Guidelines
- Use precision toolholders with runout below 0.01 mm.
- Apply a small stepover for fine surface finish in 3D contouring.
- Apply adequate coolant or compressed air to clear chips and control heat.
- Begin with conservative parameters and increase gradually based on machine condition.
- Inspect cutting edges before each use; replace if chipped or worn.
11. Toolholder Compatibility
Designed for standard ER16 / ER20 collet chucks, shrink-fit holders and hydraulic chucks with a 5 mm bore. A rigid, low-runout setup is essential for accurate contouring and surface finish.
