Product Overview
The Kyocera Z4T PR1535 CEM03688 is a precision-engineered 2.0 mm solid carbide corner-radius endmill designed for ultra-precision finishing & deep pocket milling 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 35° variable helix flute geometry, and varied interval design to suppress chatter, minimize cutting forces, and ensure stable chip evacuation. With a 20 mm flute length, it excels in deep-pocket and extended-reach applications.

Recommended Cutting Conditions
Parameters are starting recommendations for 2.0 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) | 80–120 | 0.06–0.10 | 1×D | Air / Mist |
| Alloy Steel (≤50 HRC) | 70–100 | 0.06–0.08 | 1×D | Mist / Flood |
| Stainless Steel 304/316 | 60–80 | 0.04–0.06 | 0.5–1×D | Flood |
| Cast Iron | 90–110 | 0.08–0.12 | 1–1.5×D | Air / Dry |
| Hardened Steel (50–55 HRC) | 40–60 | 0.03–0.05 | 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.
- For deep-pocket operations with long flute length, reduce ap by 20% and increase coolant flow.
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.
