1. Product Overview
The Kyocera SGM02723 is a precision-engineered 4FL Ball Nose solid carbide endmill with a nominal cutting diameter of 0.025". Manufactured in Japan from ultra-fine grain carbide substrate and coated with a high-performance AlTiN PVD multi-layer coating, this tool is designed for demanding CNC milling operations requiring exceptional surface finish, dimensional accuracy, and extended tool life.
The ball nose geometry combined with a 38° helix angle and optimized flute design ensures superior chip evacuation, reduced cutting forces, and minimal vibration — even in high-speed machining environments. Grade TA delivers outstanding wear resistance and thermal stability, making it suitable for a wide range of ferrous and non-ferrous materials.

10. Operating Guidelines
| Parameter | Recommendation |
|---|---|
| Tool Runout (TIR) | < 0.0003" (7.5 μm) |
| Coolant / Lubrication | Air blast, MQL, or soluble oil at 6-8% concentration |
| Spindle Speed | Calculate from Vc and DC; ensure stable RPM without chatter |
| Entry Strategy | Helical ramp entry at 2-3° angle; avoid direct plunge into solid material |
| Tool Overhang | Minimize overhang; use shortest toolholder possible for maximum rigidity |
| Chip Evacuation | Ensure adequate chip removal; compressed air through spindle preferred |
| Inspection | Inspect cutting edges under microscope after 50-100 min of cutting time |
11. Toolholder Compatibility
| Holder Type | Compatible Size | Recommended Use |
|---|---|---|
| Collet Chuck (ER11/ER16) | 0.125" shank | General purpose; ensure collet matches shank diameter exactly |
| Hydraulic Chuck | 0.125" shank | High-precision applications; excellent vibration damping |
| Shrink Fit Holder | 0.125" shank | Best for high-speed machining; maximum runout control |
| Milling Chuck (Power Chuck) | 0.125" shank | Heavy-duty roughing; high gripping force |
