1. Product Overview
| Manufacturer | Kyocera |
| MPN | SGS40178 |
| Tool type | Solid carbide endmill, 4 flutes, ball-nose end |
| Nominal diameter | 18.0 mm |
| Primary use | Precision CNC milling of steels, stainless steel, cast iron and non-ferrous alloys |
2. ISO Designation Breakdown
Solid endmills do not carry an ISO insert code; the product descriptor maps as follows:
| Descriptor | Interpretation |
|---|---|
| 18,0 | Nominal cutting diameter = 18.0 mm |
| 4FL | Four helical cutting flutes |
| BN | Ball-nose end geometry, R ≈ 9.0 mm |
| SGS40178 | Kyocera manufacturer part number / catalog reference |
3. Engineering Dimensions & Geometry
- Nominal diameter (D1): 18.0 mm
- Number of flutes: 4
- Corner geometry: Ball-nose, nominal radius R ≈ 9.0 mm
- Centre cutting: Yes (typical for 4-flute ball-nose designs)
- Helix angle: 30°–35° (series typical)
- Shank type: Cylindrical shank, diameter matched to cutter body
- Flute length / OAL: Standard series length
- Run-out tolerance: ≤ 0.01 mm (typical precision grade)
4. Grade Details & Characteristics
Premium micro-grain solid carbide substrate with advanced PVD coating for high-speed machining.
- Fine-grain tungsten carbide for high hardness and edge strength
- Coating reduces built-up edge and improves thermal stability
- Balanced wear resistance and toughness for intermittent cuts
- Suitable for wet and MQL/minimum-quantity lubrication machining
5. Grade Comparison Matrix
| Tool material | Hardness / heat resistance | Best suited for |
|---|---|---|
| HSS | Moderate | Low-speed general milling |
| Standard carbide | Good | Routine steel and cast iron |
| Kyocera micro-grain carbide (this tool) | Excellent | High-speed precision milling, longer tool life |
6. Chipbreaker Profile
Endmill flute geometry controls chip formation and evacuation:
- Four-flute design with robust core diameter for stability
- Helical flutes create controlled chip curl and direct evacuation axially
- Polished rake faces reduce friction and built-up edge
- Ball-nose cutting edges enable smooth 3D contouring and blended surfaces
7. Recommended Applications & Materials
| Material group | Suitability | Notes |
|---|---|---|
| Carbon & alloy steels | Excellent | Dry or emulsion coolant |
| Stainless steels | Good | Use adequate coolant to limit work hardening |
| Cast irons | Good | Dust extraction recommended |
| Non-ferrous alloys | Good | Lower cutting speeds to prevent built-up edge |
8. Application Map by Operation
| Operation | Suitability | Guidance |
|---|---|---|
| 3D contouring / profiling | Excellent | Use small step-over for fine surface finish |
| Die and mould finishing | Excellent | Ideal for fillets and complex curved surfaces |
| Pocketing | Good | Helical entry recommended |
| Slotting | Fair | Use reduced radial engagement |
9. Recommended Cutting Conditions
Starting parameters for stable setups; adjust based on machine rigidity and material condition.
| Material | Vc (m/min) | fz (mm/tooth) | Step-over / Ap |
|---|---|---|---|
| Carbon steel | 120–180 | 0.05–0.12 | Step-over ≤ 0.2D; Ap ≤ 1D |
| Stainless steel | 80–140 | 0.04–0.10 | Step-over ≤ 0.15D; Ap ≤ 1D |
| Cast iron | 100–160 | 0.06–0.14 | Step-over ≤ 0.2D; Ap ≤ 1D |
| Aluminium alloys | 200–350 | 0.08–0.18 | Step-over ≤ 0.25D; Ap ≤ 1.5D |
10. Operating Guidelines
- Mount in a precision collet or shrink-fit holder; minimise stick-out
- Prefer climb milling and consistent tool paths to reduce burr
- Ensure reliable chip evacuation; use air blast or coolant as required
- Inspect cutting edges before each use; replace if chipping or wear land appears
- Start at conservative speeds/feeds and increase incrementally
11. Toolholder Compatibility
- ER32 / ER40 collet chucks with 18 mm collet capacity
- Shrink-fit and hydraulic milling chucks for high-speed finishing
- Weldon / side-lock endmill holders for heavy roughing
- Compatible with ISO/DIN BT, HSK and CAT40/50 spindle interfaces
12. Packaging & Ordering Info
| Pack quantity | 1 piece per protective tube |
| Order code | SGS40178 |
| Storage | Keep in original packaging; protect cutting edges from impact |
