1. Product Overview
The Kyocera Z4S 0100 050 0400 010 (MPN: CEM04139) is a premium-grade solid carbide endmill engineered for ultra-precision micro-machining, finishing, and profiling operations. Featuring Kyocera's proprietary CA6535 grade with Diamond-Like Carbon (DLC) coating, this Z4S series tool delivers exceptional wear resistance, thermal stability, and cutting edge integrity under demanding production conditions.
Manufactured in Japan to ISO 9001 quality standards, the Z4S 0100 050 0400 010 is suitable for CNC machining centers, 5-axis milling machines, and high-speed machining (HSM) applications where precision and repeatability are paramount.

6. Chipbreaker Profile
The Z4S series features an optimized flute geometry designed for superior chip evacuation and reduced cutting forces:
- Flute Profile: Variable helix design with 38° primary helix and 38° secondary relief angle minimizes harmonic vibration and chatter.
- Rake Angle: Positive 8° radial rake and 5° axial rake promote efficient chip formation and reduce heat generation.
- Core Design: Reinforced core diameter of 0.65 mm provides exceptional rigidity for standard applications without compromising chip flow.
- Edge Preparation: Micro-honed cutting edge (0.015 mm radius) enhances edge stability and prevents micro-chipping during interrupted cuts.
- Chip Pocket: Deep, polished flute surfaces (Ra 0.2 μm) ensure smooth chip evacuation, preventing re-cutting and built-up edge formation.
7. Recommended Applications & Workpiece Materials
| Material Category | Examples | Suitability |
|---|---|---|
| Carbon & Alloy Steel | S45C, SCM440, SNCM439, 4140, 4340 | ★★★★★ |
| Stainless Steel | SUS304, SUS316, SUS420J2, 17-4PH | ★★★★☆ |
| Hardened Steel | SKD11, SKH51, D2, H13 (45–55 HRC) | ★★★★☆ |

| Aluminum Alloy | A5052, A6061, A7075 | ★★☆☆☆ |
8. Application Map by Operation
| Operation Type | Suitability | Notes |
|---|---|---|
| Roughing (ap > 0.5×D) | ★★☆☆☆ | Not recommended; use larger diameter or roughing tool |
| Semi-Finishing (ap = 0.2–0.5×D) | ★★★★★ | Optimal balance of productivity and surface quality |
| Finishing (ap < 0.2×D) | ★★★★★ | Excellent surface finish (Ra 0.4–0.8 μm achievable) |
| High-Speed Machining (HSM) | ★★★★☆ | Stable at spindle speeds up to 20,000 RPM (D6) |
| Plunge Milling | ★★★★☆ | Suitable for micro-hole drilling and pocketing |

9. Recommended Cutting Conditions
Parameters below are starting recommendations. Adjust based on machine rigidity, workpiece clamping, and coolant delivery.
| Workpiece Material | Cutting Speed Vc (m/min) | Feed fz (mm/tooth) | Depth ap (mm) | Width ae (mm) |
|---|---|---|---|---|
| Carbon Steel (S45C) | 80 | 0.04 | 1.5 | 0.8 |
| Alloy Steel (SCM440) | 70 | 0.03 | 1.2 | 0.6 |
| Stainless Steel (SUS304) | 60 | 0.03 | 0.8 | 0.5 |
| Hardened Steel (50 HRC) | 40 | 0.02 | 0.3 | 0.2 |
| Cast Iron (FC250) | 90 | 0.05 | 1.8 | 1.0 |
Note: For standard tools, reduce cutting speed by 15–20% and depth of cut by 10% to maintain stability.
10. Operating Guidelines
- Runout Control: Maintain total indicated runout (TIR) below 0.010 mm at the tool tip. Excessive runout accelerates uneven wear and reduces tool life by up to 40%.
- Coolant Recommendation: Use water-soluble coolant at 6–8% concentration with through-spindle delivery (70 bar minimum) for optimal chip evacuation and thermal management.
- Ramp Entry: For Z4S series, use a ramp angle of 2–3° or helical entry with a radius ≥ 1.5×D to minimize impact loading on the cutting edges.
- Speed & Feed Adjustment: Increase feed rate by 10% for every 20% reduction in depth of cut to maintain chip thickness and prevent rubbing.
- Tool Life Monitoring: Inspect flank wear (VB) every 30 minutes. Retire tool when VB exceeds 0.15 mm for finishing or 0.30 mm for roughing operations.
- Storage: Store in original packaging at 15–25°C with humidity below 60%. Avoid contact with other tools to prevent edge damage.
11. Toolholder Compatibility
| Holder Type | Specification | Compatibility |
|---|---|---|
| Spring Collet (ER) | ER16, ER20, ER25 (for 4.00 mm shank) | ★★★★☆ |
| Hydraulic Chuck | HSK-A63, HSK-E40, BT30, BT40 | ★★★★★ |
| Shrink Fit Chuck | Induction heating, 4.00 mm bore | ★★★★★ |
| Milling Chuck (Power) | Mega Chuck, New Baby Chuck series | ★★★★☆ |
| Side-Lock (Weldon) | Weldon flat required on shank | ★★★☆☆ |
Recommended: Use hydraulic or shrink-fit chucks for standard tools to minimize runout and vibration.
