1. Product Overview
The Kyocera 0.010 ENDMILL 3FL BN Grade TA (SGM03805) is a precision-engineered solid carbide micro endmill designed for high-performance CNC milling operations. Manufactured in Japan with ultra-fine grain carbide substrate and advanced TiAlN-based PVD coating, this tool delivers exceptional dimensional accuracy, superior surface finish quality, and extended tool life in demanding micro-machining applications.
With a cutting diameter of 0.010" (0.254 mm), this ball-nose endmill is optimized for 3D contouring, profiling, and finish milling of intricate geometries in steel, stainless steel, and hardened materials up to 55 HRC. The 3-flute design provides larger chip gullets for improved chip evacuation, making it ideal for slotting and pocketing applications where chip clearance is critical. The stronger core cross-section also enhances tool rigidity for improved stability in micro-machining.

| Semi-Finish Milling | ★★★★★ | Use ae ≤ 0.3 × DC for best results |
| Slot Milling | ★★★★★ | Excellent chip evacuation; primary strength of 3-flute design |
| Plunge Milling | ★★★★☆ | Stronger core allows more aggressive plunge rates |
| Trochoidal Milling | ★★★★★ | Superior chip clearance in deep pocketing |
9. Recommended Cutting Conditions
| Material | Cutting Speed Vc (m/min) | Feed per Tooth fz (mm) | ax (mm) | ae (mm) |
|---|---|---|---|---|
| Carbon Steel (< 45 HRC) | 80-120 | 0.0003-0.0005 | ≤ 1.0 × DC | 0.05–0.20 × DC |
| Stainless Steel | 60-90 | 0.0002-0.0004 | ≤ 0.8 × DC | 0.05–0.15 × DC |
| Aluminum Alloy | 150-250 | 0.0005-0.0010 | ≤ 1.5 × DC | 0.10–0.30 × DC |

Note: Values are starting recommendations. Optimize based on machine rigidity, workpiece clamping, and coolant application. Use high-pressure coolant (70+ bar) for best chip evacuation in deep cavities.
10. Operating Guidelines
- Rigidity: Ensure minimal tool overhang. Use shortest possible gauge length. Runout must be < 5 μm at tool tip.
- Coolant: Flood coolant or minimum quantity lubrication (MQL) recommended. For steel/stainless, use water-soluble coolant at 8–10% concentration.
- Speed Range: 30,000-60,000 RPM (depending on machine capability and workpiece material).
- Entry Strategy: Use helical ramp entry or circular interpolation entry. Avoid direct plunge into solid material.
- Chip Evacuation: Maintain positive chip flow. Use air blast or through-spindle coolant if available.
- Tool Life Monitoring: Monitor flank wear (VB). Replace when VB > 0.05 mm for finish operations or > 0.10 mm for roughing.
- Workholding: Rigid workpiece clamping essential. Minimize vibration for micro-diameter tools.
11. Toolholder Compatibility
| Holder Type | Specification | Compatibility |
|---|---|---|
| Collet Chuck | ER11 / ER16 precision collet (≤ 5 μm runout) | ★★★★★ Recommended |
| Hydraulic Chuck | HSK-E32 / E40, ISO 10/15 taper | ★★★★★ Excellent damping |
| Shrink Fit | 3–5 mm engagement length minimum | ★★★★☆ Good for high-speed |
| Milling Chuck | Mechanical clamping with < 10 μm runout | ★★★☆☆ Acceptable |
