1. Product Overview
The Kyocera 21/64 ENDMILL 2FL BN TN SGS39342 is a two-flute solid-carbide ball-nose end mill designed for precision CNC milling. It delivers excellent surface finish, high dimensional accuracy, and long tool life in contouring, profiling, and finishing applications.
2. ISO Designation Breakdown
| Code Element | Interpretation |
|---|---|
| 21/64 | Nominal cutter diameter in inches (≈8.33 mm) |
| ENDMILL | Solid carbide end mill category |
| 2FL | Two flutes for chip clearance and finish |
| BN | Ball nose corner geometry |
| TN | Thin-film wear-resistant coating (e.g., TiN/TiAlN style) |
| SGS39342 | Manufacturer product / catalogue number |
3. Engineering Dimensions & Geometry
| Parameter | Value |
|---|---|
| Cutter diameter | 21/64 in (≈8.33 mm) |
| Number of flutes | 2 |
| Corner radius | Ball nose (R ≈ 4.17 mm) |
| Helix angle | 30° (typical) |
| Shank diameter | 8 mm / 5/16 in (typical) |
| Overall length | 57 mm (typical) |
| Flute length | 19 mm (typical) |
| Coating | TN (gold/heat-resistant) |
4. Grade Details & Characteristics
- Substrate: fine-grain solid carbide for high hardness and edge stability.
- Coating: thin hard coating (TN family) reducing friction and built-up edge.
- Edge prep: micro-honed edge balances sharpness with chipping resistance.
- Performance: high-speed capability, good heat resistance, consistent finish.
5. Grade Comparison Matrix
| Grade family | Hardness | Heat resistance | Best suited for |
|---|---|---|---|
| TN coated carbide | High | Good | General purpose finishing, semi-finishing |
| AlCrN / advanced PVD | Very high | Excellent | Hardened steels, high-temp alloys |
| Uncoated carbide | High | Moderate | Non-ferrous, plastics |
6. Chipbreaker Profile
The two-flute design forms open, high-volume chip gullets that evacuate chips efficiently. The ball-nose profile and polished flutes reduce chip adhesion and cutting forces, making it ideal for 3D contouring and finish milling.
7. Recommended Applications & Materials
- 3D contouring, profiling, and finishing of moulds and dies
- Alloy and carbon steels
- Stainless steels (aerospace/medical)
- Cast iron
- Hardened tool steels up to ~45 HRC (typical)
- Non-ferrous alloys at reduced speeds
8. Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Contouring / 3D profiling | Excellent | Ball nose ideal for smooth curves |
| Finishing | Excellent | Low radial engagement, high speed |
| Slotting | Limited | Use square-end tool for full slots |
| Roughing | Moderate | Light radial cuts recommended |
9. Recommended Cutting Conditions
Start values for stable CNC setups; adjust based on machine, holder, and material.
| Material | Vc (m/min) | fz (mm/tooth) | ap / ae (typ) |
|---|---|---|---|
| Carbon / alloy steel | 80–150 | 0.03–0.08 | ap 1D, ae 0.1–0.2D |
| Stainless steel | 60–120 | 0.03–0.06 | ap 0.5–1D, ae 0.1D |
| Cast iron | 100–200 | 0.04–0.10 | ap 1D, ae 0.1–0.2D |
| Hardened steel (≤45 HRC) | 40–80 | 0.02–0.05 | ap 0.3–0.5D |
10. Operating Guidelines
- Clamp the shank with minimum 2/3 engagement in a precision collet or hydraulic chuck.
- Use adequate coolant or air blast to clear chips, especially in pockets and deep contours.
- Run finish passes at lower ae and higher speeds to improve surface finish.
- Verify tool run-out is below 0.01 mm for best results.
11. Toolholder Compatibility
Compatible with precision collet chucks, shrink-fit holders, hydraulic chucks, and end-mill holders matching the shank diameter listed. Use balanced holders for high-speed machining.
