1. Product Overview
The Kyocera SGS35686 is a premium 3FL solid carbide corner radius endmill featuring the PR1535 grade coating. With a 3/8" diameter and 0.090R corner radius, this tool is engineered for standard applications demanding exceptional surface finish and dimensional stability. The optimized flute geometry minimizes cutting forces while maximizing chip evacuation efficiency, making it ideal for CNC machining centers and high-speed milling operations.
Special Designation: The TB (Tapered Body) design provides enhanced rigidity and reduced chatter in deep pocket applications, allowing for greater overhang without compromising surface finish.

10. Operating Guidelines
- Ramp Entry: Use helical ramp entry at 1°-3° angle; avoid plunging directly into solid material.
- Coolant Recommendation: Flood coolant or through-spindle coolant (TSC) at 70-100 psi for optimal chip evacuation and thermal management.
- Tool Overhang: Minimize overhang to 3xD or less. For extended reach applications, reduce speed by 15-20%.
- Chip Evacuation: Ensure adequate air blast or coolant flow to prevent chip recutting, especially in pocketing and slotting operations.
- Tool Life Monitoring: Inspect cutting edges after every 30 minutes of cutting time. Replace when flank wear exceeds 0.008" or corner radius shows chipping.
- Workholding: Secure workpiece with minimal vibration. Use hydraulic or mechanical vises with serrated jaws for best results.
11. Toolholder Compatibility
| Holder Type | Compatibility | Notes |
|---|---|---|
| Hydraulic Chuck | ★★★★★ | Best damping; recommended for finishing |
| Shrink Fit | ★★★★★ | Maximum torque transmission; ideal for roughing |
| ER Collet (ER32/ER40) | ★★★★☆ | Use precision collets (AA grade) for best TIR |
| Milling Chuck | ★★★★☆ | Good for general-purpose applications |
| Side-Lock (Weldon) | ★★★☆☆ | Acceptable for roughing; may affect balance at high speed |
