Product Overview
The Kyocera Z4T PR1535 CEM03707 is a precision-engineered 4.0 mm solid carbide corner-radius endmill designed for ultra-precision finishing operations. Manufactured in Japan using Kyocera's proprietary super micro-grain carbide substrate and advanced MEGACOAT NANO PVD coating technology, this tool delivers exceptional wear resistance, mirror finish quality, and extended tool life across a broad range of workpiece materials. The Z4T series features a precision-ground R0.02 mm corner radius, optimized 30° variable helix flute geometry, and varied interval design to suppress chatter, minimize cutting forces, and ensure stable chip evacuation. With a 10 mm flute length, it excels in deep-pocket and extended-reach applications.

Recommended Cutting Conditions
Parameters are starting recommendations for 4.0 mm diameter; adjust based on machine rigidity, workpiece stability, and coolant delivery.
| Workpiece Material | Vc (m/min) | fz (mm/tooth) | ap (mm) | Coolant |
|---|---|---|---|---|
| Carbon Steel (≤45 HRC) | 100–140 | 0.10–0.14 | 1×D | Air / Mist |
| Alloy Steel (≤50 HRC) | 90–120 | 0.10–0.12 | 1×D | Mist / Flood |
| Stainless Steel 304/316 | 80–100 | 0.08–0.10 | 0.5–1×D | Flood |
| Cast Iron | 110–130 | 0.12–0.16 | 1–1.5×D | Air / Dry |
| Hardened Steel (50–55 HRC) | 60–80 | 0.07–0.09 | 0.2–0.5×D | Mist |
Operating Guidelines
- Always use shortest overhang possible to minimize vibration and deflection.
- Ensure workpiece and fixture rigidity before aggressive cuts.
- Use climb milling where possible for better surface finish and tool life.
- Reduce cutting speed by 15–20% when entering interrupted cuts or corners.
- Maintain coolant concentration between 8–12% for water-soluble coolants.
- Inspect tool after every 30 minutes of cut time in demanding applications.
- Standard flute length allows aggressive ap values with stable chip evacuation.
Toolholder Compatibility
For best results and maximum tool life, use precision toolholders with minimal runout. Ensure collet or chuck matches the 5.0 mm shank diameter.
| Holder Type | Shank Diameter | Taper | Max Runout |
|---|---|---|---|
| Hydraulic Chuck | 5.0 mm | HSK-A63 / BT40 | ≤3 µm |
| Shrink Fit | 5.0 mm | HSK-A63 / BT40 | ≤2 µm |
| Precision Collet (ER25/ER32) | 5.0 mm | BT40 / BT50 | ≤5 µm |
| Milling Chuck | 5.0 mm | HSK-A100 / BT50 | ≤4 µm |
Note: Shank diameter 5.0mm requires corresponding collet or hydraulic chuck size.
