Product Overview
The Kyocera 0.022 Ball Nose End Mill (MPN: SGM00899) is a premium solid-carbide cutting tool engineered for high-performance CNC milling operations. Featuring a 4-flute design with an optimized ball nose profile and PR1535 grade substrate, this endmill delivers exceptional dimensional accuracy, superior surface finish, and extended tool life in demanding production environments. Ideal for precision finishing, it combines advanced PVD coating technology with precision-ground geometry to minimize cutting forces and maximize chip evacuation efficiency.

Chipbreaker Profile
Although endmills do not utilize indexable chipbreaker inserts, the flute geometry of the SGM00899 acts as an integrated chip management system:
- Flute Form: Concave parabolic profile with polished rake face for efficient chip curling and evacuation.
- Core Thickness: 0.65 × Dc, providing optimal rigidity-to-chip-space ratio for 4-flute architecture.
- Edge Preparation: Micro-honed T-land (0.002–0.003 in) enhances edge stability without sacrificing sharpness.
- Flute Polishing: Mirror-finish flute surface (Ra < 0.1 μm) prevents material adhesion and built-up edge.
- Chip Load Capacity: Designed for fz = 0.0025–0.0013 in/tooth across recommended material spectrum.

Operating Guidelines
- Runout Control: Maintain total indicated runout (TIR) < 0.0004 in at the tool tip to prevent uneven wear and premature failure.
- Coolant Recommendation: Use water-soluble coolant at 6–8% concentration for steel; mist or air blast for aluminum to prevent thermal shock.
- Entry Strategy: Use ramp or helical entry at 1–2° angle; avoid direct plunging with square-end tools deeper than 0.5 × Dc.
- Chip Evacuation: Ensure adequate air blast or coolant pressure to clear chips, especially in deep-cavity 3d contouring.
- Tool Inspection: Check for coating wear (color change from bronze to silver) and edge chipping after every 30–60 minutes of cutting time.
- Speed/Feed Adjustment: Reduce Vc by 15% for interrupted cuts or thin-wall machining; increase fz by 10% for rigid setups and stable workpieces.
Toolholder Compatibility

| ER16 Collet Chuck | 0.000–0.393 in | Rigid setup for semi-finishing | 0.0004 in |
| Hydraulic Chuck | 0.000–0.500 in | Best damping, ideal for finishing | 0.0002 in |
