1. Product Overview
The Kyocera SGM00403 is a 0.036" diameter, 4-flute square solid carbide endmill engineered for precision CNC milling operations. Part of the renowned SGM series, this tool combines a sub-micro-grain carbide substrate with an advanced wear-resistant coating to deliver exceptional surface finish, dimensional accuracy, and extended tool life across a broad spectrum of workpiece materials. Designed for high-speed machining centers and rigid CNC setups, the SGM00403 minimizes chatter and vibration while maintaining tight tolerances in demanding production environments.

| Wood Composites | Moderate | Reduced speed, increased feed |
8. Application Map by Operation
| Operation Type | Suitability | Optimal Conditions |
|---|---|---|
| Slotting (Axial Depth = D1) | ★★★★★ | Vc = 80-120 m/min, fz = 0.001-0.003 mm/tooth |
| Profiling (Radial Depth < 0.5xD1) | ★★★★★ | High-speed, light depth of cut |
| Pocketing | ★★★★☆ | Helical entry, ramp angle < 2° |
| Plunging / Drilling | ★★★☆☆ | Not recommended for full plunging; use helical interpolation |
| 3D Contouring / Trochoidal | ★★★★★ | Excellent chip evacuation, constant tool engagement |
9. Recommended Cutting Conditions

| Spindle Speed (n) — Reference | 27848 RPM | 34810 RPM | 41772 RPM |
10. Operating Guidelines
- Rigidity: Ensure minimal tool overhang. Use the shortest possible toolholder and rigid collet chuck (ER16 or ER20 recommended for 0.125" shank).
- Coolant: Compressed air or mist coolant is preferred for thermal management. Flood coolant may cause thermal shock; if used, maintain consistent flow.
- Runout: Total indicated runout (TIR) at the tool tip should not exceed 0.0004" (10 μm). Excessive runout dramatically reduces tool life.
- Entry Strategy: Use helical or ramp entry at < 2° angle. Avoid direct plunging with square endmills.
- Chip Evacuation: Ensure adequate air blast or coolant pressure to clear chips from the cutting zone, especially in deep pocketing.
- Workholding: Secure workpiece firmly to prevent vibration. Damping pads may be required for thin-walled components.
11. Toolholder Compatibility
| Holder Type | Compatibility | Notes |
|---|---|---|
| ER Collet Chuck (ER16 / ER20) | Excellent | Best for general milling; ensure collet size matches shank |
| Hydraulic Expansion Chuck | Excellent | Superior damping for high-speed finishing |
| Shrink Fit Holder | Excellent | Highest rigidity and runout accuracy for precision work |
| Weldon Flat Side-Lock | Good | Suitable for heavy roughing; check set-screw alignment |
| Milling Chuck (Power Chuck) | Very Good | Good gripping force and vibration damping |
