1. Product Overview
The Kyocera Z4T 0400 060 0600 160 R020 ENDMILL CEM04046 is a precision-engineered solid carbide endmill designed for high-performance CNC milling operations. Manufactured in Japan to exacting OEM standards, this 4-flute corner-radius endmill delivers exceptional surface finish, dimensional accuracy, and extended tool life across demanding production environments.
With a 4.0 mm cutting diameter, 6.0 mm flute length, and 0.2 mm corner radius, the Z4T series is optimized for profile milling, contouring, and pocketing operations where edge quality and tool longevity are critical. The advanced carbide substrate combined with a TiAlN coating ensures stable performance at elevated cutting speeds.

5. Grade Comparison Matrix
| Grade | Coating | Target Material | Speed | Wear Resistance | Toughness |
|---|---|---|---|---|---|
| PR1205 | TiAlN | Hardened Steel, Inconel | Medium | ★★★★☆ | ★★★★★ |
| PR1530 | AlTiN | Stainless Steel, Titanium | High | ★★★★★ | ★★★★☆ |
| PR1705 | TiSiN | Cast Iron, Aluminum | Very High | ★★★★★ | ★★★☆☆ |
6. Chipbreaker Profile
Although the Z4T is a solid endmill rather than an indexable insert, its flute geometry functions analogously to a chipbreaker profile, controlling chip formation and evacuation to ensure stable cutting and superior surface finish.
| Flute Characteristic | Specification | Functional Benefit |
|---|---|---|
| Flute Profile | Variable helix, parabolic core | Reduces harmonic vibration; smooth chip flow |
| Flute Width | Optimized for 4.0 mm diameter | Maximized chip pocket volume for efficient evacuation |
| Edge Preparation | Micro-honed T-land (0.02 mm) | Prevents micro-chipping; extends edge life |
| Gash Depth | Standard | Ensures rapid chip evacuation from cutting zone |
| Core Thickness | 2.8 mm | High rigidity for aggressive milling parameters |
7. Recommended Applications & Workpiece Materials
The Z4T CEM04046 is optimized for the following material groups and machining scenarios:
| Material Group | Examples | Hardness Range | Suitability |
|---|---|---|---|
| Carbon Steel | Typical grades | ≤ 200 HB | ★★★★★ Excellent |
| Tool Steel (≤HRC 50) | Typical grades | 45 – 55 HRC | ★★★★☆ Very Good |
| Stainless Steel | Typical grades | ≤ 280 HB | ★★★★☆ Very Good |
| Titanium Alloys | Typical grades | ≤ 350 HB | ★★★☆☆ Good |
8. Application Map by Operation

| Workpiece Material | Cutting Speed Vc (m/min) | Feed per Tooth fz (mm) | Axial Depth ap (mm) | Radial Depth ae (mm) |
|---|---|---|---|---|
| Carbon Steel (≤HRC 30) | 100-140 | 0.03-0.08 | ≤ 4.8 | ≤ 3.0 |
| Alloy Steel (≤HRC 40) | 80-120 | 0.03-0.08 | ≤ 3.8 | ≤ 2.4 |
| Stainless Steel (304/316) | 70-100 | 0.02-0.05 | ≤ 3.4 | ≤ 2.0 |
| Aluminum Alloy (6061/7075) | 250-350 | 0.04-0.10 | ≤ 4.8 | ≤ 3.6 |

10. Operating Guidelines
- Run-out Check: Ensure tool run-out at the cutting edge is ≤ 0.01 mm. Excessive run-out accelerates uneven wear and reduces tool life.
- Coolant Strategy: For steel and stainless steel, use high-pressure coolant (≥ 70 bar) directed precisely at the cutting zone. For aluminum, compressed air or MQL is often preferable to prevent built-up edge.
- Entry Strategy: Avoid direct plunge. Use helical or ramp entry with a maximum ramp angle of 2°. Pre-drill a starter hole if plunge entry is unavoidable.
- Chip Evacuation: Maintain adequate chip evacuation to prevent recutting. Compressed air blast or through-spindle coolant is highly recommended for pocketing operations.
- Tool Overhang: Minimize overhang to 4×D or less. For the 4.0 mm diameter, keep stick-out below 16.0 mm whenever possible. Use hydraulic or shrink-fit holders for best rigidity.
- Speed & Feed Tuning: Start at the lower end of the recommended Vc/fz range and increase incrementally while monitoring tool wear and surface finish. Listen for chatter and adjust accordingly.
- Corner Radius Benefit: The 0.2 mm corner radius distributes cutting forces across a larger edge segment, reducing chipping risk and extending tool life compared to sharp corners.
11. Toolholder Compatibility
The 4.0 mm shank diameter is compatible with standard ER collet systems, shrink-fit holders, and hydraulic chucks. Recommended clamping configurations:
| Holder Type | Collet / Chuck Size | TIR (Max) | Best For |
|---|---|---|---|
| ER Collet Chuck | ER16 / ER20 / ER25 | ≤ 0.015 mm | General milling; cost-effective |
| Shrink-Fit Holder | HSK-A63 / HSK-E40 | ≤ 0.005 mm | High-speed finishing; minimal run-out |
| Hydraulic Chuck | Standard bore 6.0 mm | ≤ 0.003 mm | Precision contouring; heavy milling |
| Milling Chuck (Power Chuck) | Standard bore 6.0 mm | ≤ 0.010 mm | Roughing; high torque transmission |
