Kyocera SGM02267 PR1725 0.034mm 4FL Square Solid Carbide Endmill
1. Product Overview
The Kyocera SGM02267 is a precision-engineered solid carbide endmill featuring 4FL flute design with square geometry. Manufactured from super micro-grain carbide substrate and coated with MEGACOAT HARD PVD technology, this tool delivers exceptional performance for high-precision CNC milling operations. The 0.034mm cutting diameter combined with optimized helix angle (35°) ensures superior chip evacuation, reduced cutting forces, and extended tool life across a broad spectrum of workpiece materials.

8. Application Map by Operation
| Operation | Suitability | Recommended ae/ap | Notes |
|---|---|---|---|
| Slotting | ★★★★★ | ae = 0.034mm / ap = 1×Dc | Optimal for square endmills |
| Shouldering | ★★★★★ | ae = 0.5×Dc / ap = 1–2×Dc | Excellent wall finish quality |
| Profiling / Contouring | ★★★★☆ | ae = 0.1–0.3×Dc / ap = 0.5×Dc | Good for 2.5D profiles |
| Pocketing | ★★★★☆ | ae = 0.6×Dc / ap = 1×Dc | Helical ramp entry recommended |
| Plunge Milling | ★★★☆☆ | ae = 0.3×Dc / ap = 0.5×Dc | Center-cutting capability required |
| High-Feed Milling | ★★★★☆ | ae = 0.2×Dc / ap = 0.1×Dc | Reduced depth for high table feeds |
9. Recommended Cutting Conditions
Values are starting recommendations. Adjust based on machine rigidity, workpiece material condition, and coolant application.
| Workpiece Material | ISO Group | Vc (m/min) | fz (mm/tooth) | ap (mm) | Coolant |
|---|---|---|---|---|---|
| Carbon Steel (C45) | P | 126.0 | 0.087 | 0.0 | Emulsion / Compressed Air |
| Stainless Steel (304) | M | 79.0 | 0.064 | 0.0 | Water-Soluble Coolant |
| Gray Cast Iron (GG25) | K | 104.0 | 0.101 | 0.0 | Dry / Compressed Air |
| Aluminum (6061-T6) | N | 210.0 | 0.124 | 0.0 | Air Blast / MQL |
| Titanium (Ti-6Al-4V) | S | 41.0 | 0.049 | 0.0 | High-Pressure Coolant |
10. Operating Guidelines
- Tool Runout: Maintain maximum tool runout of 0.01 mm (TIR) at the cutting edge. Excessive runout reduces tool life by 30–50%.
- Spindle Speed: Calculate n = (1000 × Vc) / (π × Dc). For 0.034mm at 126.0 m/min: n ≈ 1179619 RPM.
- Feed Rate: Vf = fz × Z × n. At 0.087 mm/tooth with 4 flutes: Vf ≈ 410507.0 mm/min.
- Entry Strategy: Use helical ramp entry (2°–5° angle) or circular interpolation entry. Avoid direct plunge except for center-cutting tools.
- Coolant: For steel and cast iron, compressed air or emulsion coolant is recommended. For stainless steel and titanium, high-pressure water-soluble coolant is essential.
- Tool Overhang: Minimize overhang to ≤ 4×Dc for optimal stability. Use hydraulic or shrink-fit holders for best results.
- Chip Evacuation: Ensure adequate chip evacuation to prevent recutting, which causes premature wear and poor surface finish.
- Tool Life Monitoring: Monitor flank wear (VB). Recommended regrind limit: VB = 0.15 mm for finishing, VB = 0.25 mm for roughing.
11. Toolholder Compatibility
| Holder Type | Compatibility | Recommended For |
|---|---|---|
| Hydraulic Chuck (H) | ★★★★★ | High-precision finishing, minimal runout |
| Shrink Fit Holder | ★★★★★ | Maximum rigidity, high-speed machining |
| Collet Chuck (ER32/ER40) | ★★★★☆ | General-purpose milling, versatile |
| Weldon Flat Holder | ★★★★☆ | Heavy roughing, positive drive |
| Milling Chuck (Power) | ★★★★☆ | High-torque applications, large diameters |
Shank Compatibility: DIN 6535 HA cylindrical shank with h6 tolerance. Optional Weldon flat available for enhanced torque transmission.
