Product Overview
The Kyocera Z5T CEM02499 is a precision-engineered solid carbide corner-radius endmill designed for high-performance CNC milling operations. Featuring a 1.5mm cutting diameter, 5mm flute length, and 0.2mm corner radius with 8mm extended neck reach, this tool delivers exceptional dimensional accuracy, superior surface finish, and extended tool life in demanding production environments.
Manufactured from ultra-fine grain carbide with an advanced AlCrN Nano-Composite coating, the Z5T series minimizes cutting forces, reduces heat generation, and ensures stable chip evacuation across a wide range of workpiece materials. Ideal for deep cavity and pocket machining applications.

|---|---|---|---|---|
| Carbon Steel (≤ 45 HRC) | 80-120 | 0.01-0.03 | 0.1-0.5 | Emulsion / MQL |
| Stainless Steel (304/316) | 60-90 | 0.01-0.03 | 0.1-0.5 | High-pressure coolant |
| Aluminum Alloy | 150-200 | 0.01-0.03 | 0.1-0.5 | Air blast / MQL |

Operating Guidelines
- Runout Check: Ensure tool runout is less than 0.01 mm to prevent uneven wear and premature failure.
- Coolant Strategy: Use through-spindle coolant whenever possible for effective chip evacuation, especially in pocket and cavity milling.
- Entry Method: Use helical or ramp entry into the workpiece. Avoid direct plunge with this endmill.
- Chip Evacuation: Maintain adequate coolant flow to prevent chip recutting, which degrades surface finish and tool life.
- Tool Overhang: Minimize overhang to 3×DC or less for standard operations; up to 5×DC for neck-type tools with reduced parameters.
- Workpiece Fixturing: Ensure rigid workholding to minimize vibration and chatter during high-speed operations.
- Inspection: Inspect tool edges before each use; do not use if chipping or micro-fractures are visible.
Toolholder Compatibility
| Holder Type | Compatibility | Recommendation |
|---|---|---|
| Spring Collet (ER16 / ER20) | Compatible | Standard for general milling; ensure proper torque |
| Hydraulic Chuck | Highly Recommended | Best runout accuracy (< 0.003 mm) |
| Shrink Fit Holder | Highly Recommended | Optimal for high-speed machining |
| Milling Chuck (Power Grip) | Compatible | Good gripping force for heavy cuts |
| Weldon Side-Lock | Not Recommended | May cause runout issues in small diameters |
