1. What is the recommended application for a 4mm endmill?
It’s perfect for mid-range precision milling, especially in contouring, profiling, and finishing tasks in hard and soft metals.
2. Can this endmill handle high-speed machining?
Yes, the solid carbide body and heat-resistant coating allow it to perform well in high-speed operations with reduced wear.
3. What spindle speed is ideal for this tool?
Spindle speed depends on the material, but typically ranges from 10,000 to 25,000 RPM for metals and lower for softer materials.
4. Is it compatible with manual milling machines?
It can be used with manual machines if they support 4mm shanks and appropriate RPMs, but it performs best in CNC environments.
5. Does the coating improve the surface finish?
Yes, the coating reduces friction and heat buildup, resulting in cleaner cuts and a better overall surface
