1. Product Overview
The Kyocera 1,50 ENDMILL 2FL BN TA SGM02920 is a precision-engineered solid carbide endmill manufactured in Japan. Designed for high-performance CNC milling operations, this 1,50" diameter ball-nose endmill delivers exceptional surface finish, dimensional accuracy, and extended tool life in demanding machining environments. The 2FL design with TA (TiAlN-based nano composite) coating ensures superior heat resistance and wear protection for continuous production runs.

7. Recommended Applications & Workpiece Materials
| Material | Machinability | Notes |
|---|---|---|
| Carbon Steel (≤45 HRC) | ★★★★★ Excellent | Primary application — high speed capable |
| Alloy Steel (4140, 4340) | ★★★★★ Excellent | Optimal chip control and tool life |
| Stainless Steel (304/316) | ★★★★☆ Very Good | Use flood coolant to prevent work hardening |
| Tool Steel (H13, D2) | ★★★★☆ Very Good | Reduce speed 20% for pre-hardened grades |
| Titanium (Ti-6Al-4V) | ★★★★☆ Very Good | Low speed, high feed strategy recommended |
| Aluminum (≤6061) | ★★★☆☆ Good | Polished flute recommended for best results |
8. Application Map by Operation
| Operation | Suitability | Recommended Parameters |
|---|---|---|
| 3D Profiling / Finishing | ★★★★★ Ideal | Stepover: 3-5% of DC |
| Slotting | ★★★★☆ Very Good | DOC: 1.0× DC max; Reduce feed 20% |
| Pocketing / Adaptive | ★★★★★ Ideal | Radial WOC: 5–8% of DC; High feed strategy |
| Ramping / Helical Entry | ★★★★☆ Very Good | Max ramp angle: 2°; Helical diameter: 1.2× DC |
| Plunging | ★★☆☆☆ Limited | Not recommended — use ramp entry only |
| Trochoidal Milling | ★★★★★ Ideal | Optimal for tool life in deep pocketing |
9. Recommended Cutting Conditions
| Workpiece Material | Vc (SFM) | fz (inch/tooth) | ap (Axial DOC) | ae (Radial WOC) |
|---|---|---|---|---|
| Mild Steel (1018) | 200–250 | 0.0008–0.0012 | 1.0× DC | 0.05× DC |
| Alloy Steel (4140) | 150–200 | 0.0006–0.0010 | 1.0× DC | 0.05× DC |
| Stainless Steel (304) | 120–160 | 0.0005–0.0008 | 0.8× DC | 0.04× DC |
| Tool Steel (H13, ≤50 HRC) | 100–140 | 0.0004–0.0007 | 0.7× DC | 0.03× DC |
| Titanium (Ti-6Al-4V) | 80–120 | 0.0004–0.0007 | 0.6× DC | 0.03× DC |
| Aluminum (6061-T6) | 300–400 | 0.0010–0.0015 | 1.2× DC | 0.08× DC |
10. Operating Guidelines
- Spindle Speed: Calculate RPM from Vc and tool diameter. Example: At 200 SFM with 1,50" diameter, RPM ≈ 509. Always verify machine spindle capability.
- Coolant Strategy: Flood coolant or through-spindle MQL (Minimum Quantity Lubrication) is strongly recommended. Avoid dry cutting or air blast alone for steel applications.
- Runout Control: Maintain tool runout (TIR) less than 0.0002" (5 μm) at the tool tip. Excessive runout dramatically reduces tool life.
- Rigidity: Minimize tool stick-out. Use the shortest possible gauge length and robust toolholder for maximum stability.
- Entry Strategy: Always use ramping or helical entry. Never plunge directly into solid material with this ball-nose endmill.
- Tool Life Monitoring: Monitor flank wear (VB) regularly. Recommended replacement when VBmax reaches 0.004" (0.1 mm) or when surface finish degrades.
- Workholding: Ensure rigid workpiece fixturing. Vibration from loose workholding is the primary cause of premature tool failure in milling.
11. Toolholder Compatibility
| Holder Type | Collet / Bore Size | Compatibility |
|---|---|---|
| ER Collet Chuck | ER11 (0.236") / ER16 (0.236") | ★★★★★ Recommended — widely available |
| Shrink Fit Holder | 6.0 mm / 0.236" | ★★★★★ Best for high-speed machining |
| Hydraulic Chuck | 5.8–6.5 mm range | ★★★★☆ Excellent damping properties |
| Milling Chuck (Power Chuck) | 0.236" (6.0 mm) | ★★★★☆ Suitable for general use |
| Collet Block (Manual) | 0.236" R8 / 5C | ★★★☆☆ Acceptable for low-speed ops |
