1. Product Overview
The Kyocera 1/2 ENDMILL 5FL CBTM SGS37513 is a premium solid carbide end mill engineered for high-performance CNC milling operations. Manufactured in Japan to exacting tolerances, this 5fl tool features ultra-fine grain carbide (0.5 μm) and a AlCrN PVD coating for exceptional wear resistance and thermal stability.
Designed for hardened steel applications, this end mill delivers mirror-finish surface quality, extended tool life, and consistent dimensional accuracy across high-volume production runs. The 42° helix angle optimizes chip evacuation while minimizing cutting forces and vibration.

10. Operating Guidelines
- Tool Runout: Ensure total indicator runout (TIR) at the tool tip does not exceed 0.01 mm. Excessive runout causes uneven flute loading and premature failure.
- Ramp Entry: When entering the workpiece, use a helical ramp angle of 1°–2° or less. Avoid plunging directly unless center-cutting capability is confirmed.
- Chip Evacuation: Maintain adequate coolant flow or compressed air to clear chips from the cutting zone. Recutting chips is the leading cause of edge chipping.
- Depth-of-Cut Strategy: For deep cavities, reduce axial depth (ap) to 0.5×D and increase radial engagement (ae) to improve chip thinning and reduce heat.
- Tool Overhang: Minimize tool overhang (stick-out) to the shortest practical length. Every 1×D increase in overhang reduces effective rigidity by approximately 75%.
- Wear Monitoring: Inspect tool edges after every 30–60 minutes of cutting time. Look for uniform flank wear (VB max = 0.2 mm) as the primary wear indicator.
- Storage: Store end mills in original packaging or protective tubes. Avoid contact between cutting edges to prevent chipping or micro-fractures.
