1. Product Overview
The Kyocera 1/8 ENDMILL 4FL BN TC SGS39614 is a 4-flute ball-nose solid carbide end mill engineered for precision CNC milling. The tungsten carbide (TC) substrate delivers high rigidity, heat resistance, and extended edge life in contouring, 3D profiling, and finishing operations.
2. ISO Designation Breakdown
| Code Element | Meaning |
|---|---|
| Kyocera | Manufacturer / brand |
| 1/8 | Nominal cutting diameter (inch) |
| ENDMILL | Solid rotary end mill tool family |
| 4FL | Four cutting flutes |
| BN | Ball-nose end geometry |
| TC | Tungsten carbide substrate |
| SGS39614 | Manufacturer catalog part number |
3. Engineering Dimensions & Geometry
- Nominal diameter: 1/8 in (3.175 mm)
- Flutes: 4
- Corner geometry: Ball nose (hemispherical)
- Helix angle: ~30° typical for general-purpose 4-flute end mills
- Shank diameter: 1/8 in straight shank
- Overall length: Standard catalog length for SGS39614
- Coating: As specified in Kyocera catalog for SGS39614
4. Grade Details & Characteristics
Constructed from fine-grain tungsten carbide for balanced hardness and toughness. Suitable for milling steels, stainless steels, cast iron, and non-ferrous materials at elevated cutting speeds.
- Substrate: Micro-grain tungsten carbide
- Binder: Cobalt-based
- Hardness: ~91–92 HRA
- Application range: General engineering to semi-finishing
5. Grade Comparison Matrix
| Grade family | Hardness | Toughness | Best for |
|---|---|---|---|
| Uncoated TC | High | Good | Aluminium, brass, plastics |
| TiAlN-coated | Very high | Good | Steel, alloy steel, stainless |
| TiN/TiCN-coated | High | Very good | General-purpose mixed materials |
6. Chipbreaker Profile
The 4-flute design with open chip gullets provides efficient chip evacuation and stable core strength. Ball-nose geometry produces controlled chip thinning and consistent surface finish during 3D contouring.
7. Recommended Applications & Materials
- Mild and alloy steels
- Stainless steels (preliminary / medium machining)
- Cast iron
- Aluminium and copper alloys
- Plastics and composites (depending on coating / edge condition)
8. Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| 3D profiling / contouring | Excellent | Ball-nose geometry ideal for curved surfaces |
| Slotting | Limited | Use square-end version for full-width slots |
| Pocketing / roughing | Good | Reduce radial engagement to protect corners |
| Finishing | Excellent | High step-over delivers fine surface finish |
9. Recommended Cutting Conditions
Starting parameters for carbide-speed applications; adjust for machine rigidity and workpiece condition.
| Workpiece | Vc (SFM) | fz (IPT) | DOC max |
|---|---|---|---|
| Mild steel | 200–350 | 0.001–0.003 | 1×D |
| Stainless steel | 120–250 | 0.001–0.002 | 0.5×D |
| Aluminium | 400–800 | 0.002–0.005 | 1.5×D |
| Cast iron | 150–300 | 0.001–0.003 | 1×D |
10. Operating Guidelines
- Use minimum quantity lubrication (MQL) or flood coolant for steel and stainless steel.
- Maintain run-out below 0.01 mm for best tool life and finish.
- Ramp or helical entry recommended; avoid plunging directly with ball-nose tools.
- Secure collet / holder every tool change; check for chip damage before reuse.
11. Toolholder Compatibility
- ER collet chucks (ER11 / ER16 / ER20 depending on shank)
- Straight-shank end mill holders
- Shrink-fit and milling chucks with 1/8 in capacity
- Compatible with vertical machining centres, horizontal mills, and CNC routers
12. Packaging & Ordering Info
- Supplied in protective single-piece plastic tube or blister pack
- Minimum order quantity: 1 piece
- Bulk pricing available on request
- MPN / catalog reference: SGS39614
