1. Product Overview
The SGM02607 is a premium-grade solid carbide ball-nose endmill from Kyocera's SGM series, engineered for precision CNC machining applications. Featuring a 0.042" (1.067 mm) cutting diameter with 4FL flute configuration and Grade TA substrate, this tool delivers exceptional surface finish quality, dimensional accuracy, and extended tool life in demanding production environments.
Manufactured in Japan using Kyocera's proprietary MEGACOAT NANO PVD coating technology, the SGM02607 combines a super micro-grain carbide substrate with an advanced multi-layer coating structure optimized for high-precision finishing, semi-finishing, and light roughing of steels, stainless steels, and cast irons.

6. Chipbreaker Profile
The SGM02607 features Kyocera's proprietary BN (Ball-Nose) chipbreaker geometry, specifically designed for ball-nose endmill applications:
- Ball-Nose Radius Precision: The cutting edge radius is precisely ground to 0.021" (0.5334 mm) Ball, ensuring accurate 3D profiling and contouring without steps or faceting.
- Optimized Flute Curvature: Tighter flute spacing with reinforced core provides superior rigidity for high-feed-rate machining.
- Edge Preparation: Sharp, honed cutting edge minimizes burr formation and delivers mirror-finish surfaces on precision components.
- Helix Angle Optimization: 35° helix angle provides superior surface finish and reduced vibration at high feed rates.
7. Recommended Applications & Workpiece Materials

| Pre-Tapping | Recommended for blind holes | Prevents chip packing in deep cavities |
| Entry Angle | ≤5° for ramping | Steeper angles require reduced feed |
| Corner Engagement | Reduce feed by 30% | Prevents shock loading at corners |
