1. Product Overview
The 2KMBL0350-1500-S6 is a premium solid carbide ball nose endmill from Kyocera's 2KMBL series, engineered for high-precision 3D contouring, profiling, and finish milling operations. With a 3.5mm diameter and 15.0mm cutting length, this 2-flute tool delivers exceptional surface finish quality and dimensional accuracy across demanding CNC machining applications. The S6 grade substrate with AlTiN coating ensures extended tool life even at elevated cutting speeds.

4. Grade Details – Key Grade Characteristics
S6 is Kyocera's advanced ultra-fine grain carbide grade optimized for high-speed finishing and semi-finishing of hardened steels, stainless steels, and titanium alloys. Key characteristics include:
- Ultra-fine WC grain structure (0.5 μm) for superior edge sharpness and wear resistance
- AlTiN PVD multi-layer coating (2–4 μm) for enhanced heat resistance up to 900°C
- High transverse rupture strength (4,200 MPa) minimizing chipping in interrupted cuts
- Low coefficient of friction reducing built-up edge and improving surface finish
- Optimized cobalt binder (10% Co) balancing hardness and toughness

Note: Values are starting recommendations. Adjust based on machine rigidity, coolant delivery, and workpiece fixturing.
10. Operating Guidelines
- Coolant: High-pressure internal coolant (70+ bar) recommended for deep cavity work; alternatively, minimal quantity lubrication (MQL) or air blast for heat-resistant alloys.
- Runout: Maintain tool runout ≤ 5 μm at the tool tip. Use precision shrink-fit or hydraulic chucks.
- Ramp Entry: Use helical ramp entry with angle ≤ 2° to minimize impact loading on the ball nose center.
- Stepover: For finishing, keep radial stepover (ae) at 3–5% of cutting diameter to maximize cusp height control and surface quality.
- Chip Evacuation: Ensure adequate chip evacuation to prevent re-cutting, especially in deep pockets and blind cavities.
- Tool Life Monitoring: Monitor flank wear (VB). Recommended regrind or replacement when VB = 0.1–0.15 mm for finishing operations.
11. Toolholder Compatibility
| Holder Type | Compatibility | TIR Limit |
|---|---|---|
| Shrink-Fit Chuck | Recommended | ≤ 3 μm |
| Hydraulic Chuck | Recommended | ≤ 5 μm |
| Precision Collet (ER16/ER20) | Suitable | ≤ 10 μm |
| Weldon Flat Holder | Not Recommended | — |
