1. Product Overview
The Kyocera 1/64 ENDMILL 4FL BN TC SGS39002 is a micro-diameter solid carbide end mill with a 4-flute ball-nose geometry. Designed for high-precision CNC milling, it delivers accurate 3D contours, smooth surface finish, and stable chip evacuation in delicate micro-machining tasks.
2. ISO Designation Breakdown
| Field | Code | Meaning |
|---|---|---|
| Manufacturer | Kyocera | Premium cutting tool brand |
| Diameter | 1/64 | Nominal cutter diameter in inches (0.0156") |
| Tool Type | ENDMILL | Solid end milling cutter |
| Flutes | 4FL | Four cutting flutes |
| End Geometry | BN | Ball-nose radius tip |
| Material | TC | Tungsten carbide substrate |
| Product Code | SGS39002 | Manufacturer catalog number |
3. Engineering Dimensions & Geometry
| Parameter | Value |
|---|---|
| Nominal Diameter | 1/64" (0.0156 in / 0.40 mm) |
| Number of Flutes | 4 |
| Corner Radius | Ball-nose (R = 0.20 mm) |
| Helix Angle | 30° typical (consult datasheet) |
| Shank Diameter | Standard 1/8" or 3 mm (refer to manufacturer spec) |
| Overall Length | Refer to Kyocera catalog drawing |
| Coating | Typically TiAlN / AlTiN (confirm with datasheet) |
4. Grade Details & Characteristics
Manufactured from ultra-fine grain tungsten carbide, this end mill offers high hardness, excellent wear resistance, and good edge retention. The substrate is engineered for stability in high-speed micro-milling and is compatible with modern PVD coatings for extended tool life.
- Ultra-fine grain carbide structure for high hardness
- Balanced toughness and wear resistance
- Compatible with high-temperature PVD coatings
- Optimized for HSM and precision finishing
5. Grade Comparison Matrix
| Grade/Style | Application | Characteristics |
|---|---|---|
| SGS39002 (BN) | 3D contouring, finishing | Ball-nose, high finish, low cutting force |
| SGS39003 (SQ) | Slotting, profiling, square walls | Square end, strong corners, versatile |
| 2FL Micro-Endmill | Plastics, aluminium | Large chip space, lower rigidity |
| 4FL Standard Endmill | Steel, stainless steel | Higher feed, better finish |
6. Chipbreaker Profile
This 4-flute design features a controlled flute geometry that acts as a chip evacuation channel. The ball-nose tip creates a smooth chip curl while the helical flutes lift chips away from the cutting zone, reducing recutting and heat buildup.
7. Recommended Applications & Materials
- Micro 3D contouring and profiling
- Mould and die finishing
- Medical device components
- Aerospace precision parts
- Suitable for: hardened steels, stainless steels, titanium alloys, nickel-based alloys, and non-ferrous materials (subject to grade/coating)
8. Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| 3D Contouring | Excellent | Ideal for ball-nose geometry |
| Profiling | Good | Light radial cuts recommended |
| Slotting | Limited | Very low ae due to small diameter |
| Roughing | Not recommended | Tool too small for heavy stock removal |
| Finishing | Excellent | High surface finish capability |
9. Recommended Cutting Conditions
Start values for stable setups. Reduce speeds/feeds for long overhangs or difficult materials.
| Material Group | Cutting Speed (Vc) | Feed per Tooth (fz) | Axial Depth (ap) | Radial Depth (ae) |
|---|---|---|---|---|
| Carbon Steel | 60-100 m/min | 0.002-0.006 mm | 0.04-0.20 mm | 0.02-0.10 mm |
| Stainless Steel | 40-70 m/min | 0.002-0.005 mm | 0.03-0.15 mm | 0.02-0.08 mm |
| Titanium Alloy | 25-50 m/min | 0.002-0.004 mm | 0.02-0.10 mm | 0.01-0.05 mm |
| Aluminium | 120-200 m/min | 0.004-0.010 mm | 0.05-0.30 mm | 0.03-0.15 mm |
10. Operating Guidelines
- Use minimal run-out precision collets or shrink-fit holders
- Apply high-pressure air or mist coolant for chip evacuation
- Avoid excessive axial depth to prevent deflection
- Use trochoidal or adaptive toolpaths for longer tool life
- Verify spindle speed and feed calculations before starting
11. Toolholder Compatibility
This micro-end mill is compatible with precision collet chucks, shrink-fit holders, and hydraulic chucks with matching shank diameter. Use balanced toolholders for high-speed spindles to minimise vibration and run-out.
- ER11 / ER16 / ER20 precision collet systems
- Shrink-fit holders with H4 or better bore tolerance
- Hydraulic mini holders for damped clamping
