Grade Details - Key Grade Characteristics
The 2KMBL0160-0800-S4 utilizes Kyocera's proprietary ultra-fine grain carbide substrate (grain size 0.5 μm) with an advanced PVD multi-layer coating system. This substrate-coating combination delivers:
- Hardness: 92.5 HRA substrate hardness with 3500 HV coating surface hardness
- Transverse Rupture Strength: 4,200 MPa - exceptional resistance to chipping and fracture
- Coating Architecture: TiAlN base layer + TiSiN top layer for oxidation resistance up to 1,100°C
- Coating Thickness: 2.5 ± 0.3 μm total coating thickness
- Coefficient of Friction: 0.35 (dry) - minimizes built-up edge and improves chip flow
- Thermal Conductivity: 80 W/m·K - efficient heat dissipation from cutting edge

Chipbreaker Profile
The 2KMBL0160-0800-S4 features a optimized for fine chip evacuation in narrow slots and cavities. The flute geometry incorporates:
- Variable Helix Design: Reduces harmonic vibration and chatter during high-speed machining
- Positive Rake Angle: 12° radial rake angle minimizes cutting forces and heat generation
- Wide Flute Gullet: Optimized cross-sectional area for efficient chip evacuation, preventing re-cutting
- Polished Flute Surface: Ra 0.15 μm surface roughness reduces chip adhesion and built-up edge
- Edge Preparation: Controlled honing of 0.01-0.02 mm ensures edge stability without compromising sharpness
Recommended Applications & Workpiece Materials
This endmill is specifically optimized for machining hardened steels up to 55 HRC, stainless steels, and titanium alloys. The 4-flute design provides the ideal balance between chip space and tool rigidity for the 1.6 mm diameter class.

Operating Guidelines
- Coolant Strategy: External flood coolant with minimum 6 L/min flow rate. Through-tool coolant not available for diameters below 2.0 mm.
- Runout Tolerance: Maintain total indicated runout (TIR) below 0.01 mm at the tool tip for optimal tool life and surface finish.
- Depth of Cut: For roughing, limit axial depth to 2.4 mm (1.5× tool diameter). For finishing, reduce to 0.5 mm maximum.
- Entry Strategy: Use helical ramp entry with maximum 5° ramp angle. Avoid direct plunging into solid material.
- Tool Overhang: Minimize overhang to 33 mm or less. Excessive overhang promotes vibration and reduces tool life.
- Pre-Machining Inspection: Verify tool integrity and edge condition before use. Do not use tools with visible chipping or coating delamination.
- Workpiece Fixturing: Ensure rigid clamping to prevent workpiece movement. Vibration is the primary cause of premature tool failure in small-diameter endmills.
Toolholder Compatibility
| Holder Type | Collet / Bore Size | Compatibility | Notes |
|---|---|---|---|
| Spring Collet (ER) | ER11 / ER16 (≥ 1.6 mm) | ★★★★★ Excellent | Use high-precision collet (AA class) for best results |
| Hydraulic Chuck | H6 (6 mm bore) | ★★★★★ Excellent | Best vibration damping for high-speed finishing |
| Shrink Fit Holder | 6 mm | ★★★★☆ Very Good | Excellent runout control; requires induction heating system |
| Milling Chuck (Power Chuck) | 6 mm | ★★★★☆ Very Good | Good gripping force; suitable for heavy roughing |
| Weldon Side-Lock | 6 mm | ★★★☆☆ Good | Acceptable for lower-speed applications; check runout carefully |
