1. Product Overview
The Kyocera SGM01618 is a precision-engineered 3-flute ball nose solid carbide endmill from the SGM series. Designed for micro & precision machining, this 0.0400" diameter tool features MEGACOAT NANO coating and ultra-fine grain carbide substrate for exceptional wear resistance, heat tolerance, and surface finish quality. The 30° helix angle ensures smooth chip evacuation while the optimized core geometry provides the rigidity needed for demanding CNC operations.

8. Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| 3D Profiling / Contouring | ★★★★★ Excellent | Ball nose ideal for complex surfaces |
| Pocketing | ★★★★☆ Very Good | Use reduced stepover for best finish |
| Slotting | ★★★☆☆ Good | Limited by LOC; reduce ap accordingly |
| Plunge Milling | ★★☆☆☆ Fair | Not recommended; use center-cutting square endmill |
| Ramping / Helical Entry | ★★★★☆ Very Good | Max ramp angle 3° for micro diameters |
| Engraving / Marking | ★★★★★ Excellent | Sharp edge produces clean lettering |
9. Recommended Cutting Conditions
| Parameter | Value | Unit |
|---|---|---|
| Cutting Speed (Vc) | 30 - 80 | m/min (SFM × 0.305) |
| Feed per Tooth (fz) | 0.002 - 0.008 | mm/tooth (inch × 25.4) |

| Radial Depth (ae) | ≤ 0.004 | inch |
| Spindle Speed Range | 15,000 - 40,000 | RPM |
| Coolant | Mist / Air blast recommended | — |
10. Operating Guidelines
- Run-in Procedure: Reduce feed by 30% for the first 5 minutes of operation to allow coating adaptation.
- Tool Overhang: Keep overhang ≤ 4×DC for optimal rigidity. Use shortest possible tool holder.
- Chip Evacuation: Ensure adequate coolant flow or air blast to prevent chip recutting, especially in deep pockets.
- Stepover Recommendation: For finishing, use 5-10% of DC (0.0005-0.001" for this diameter) to achieve mirror surface finish.
- Entry Strategy: Use helical ramp entry at ≤ 3° angle. Avoid direct plunge with ball nose tools.
- Tool Life Indicator: Monitor surface finish degradation and spindle load increase. Re-sharpen or replace when Ra increases by 50%.
11. Toolholder Compatibility
| Holder Type | Compatible Series | Recommendation |
|---|---|---|
| Collet Chuck | ER11, ER16, ER20 (precision collet) | Standard clamping, high versatility |
| Hydraulic Chuck | HydroForce, MegaE Chuck | Best for high-speed, minimal runout |
| Shrink Fit | HSK-A63, HSK-E32/E40 | Maximum rigidity, recommended for micro-tools |
| Min. TIR Required | ≤ 0.005 mm (0.0002") | Critical for tool life and surface finish |
