1. What type of machining is the 2mm endmill suitable for?
The 2mm endmill is ideal for precision CNC machining of small components, fine slotting, engraving, and contouring. It’s commonly used in electronics, medical device manufacturing, and micro-mold industries.
2. Can I use this tool on hard metals like stainless steel?
Yes, the solid carbide construction and coating allow the 2mm endmill to handle stainless steel, alloy steel, and even hardened materials when used with the correct speeds and feeds.
3. What are the benefits of a 4-flute design at this size?
The 4-flute configuration provides better rigidity and surface finish compared to 2-flute designs. It also improves tool stability and chip load distribution during fine-detail machining.
4. What spindle speed is recommended for this tool?
Due to the small diameter, higher spindle speeds (typically 18,000–30,000+ RPM) are recommended, depending on the material and desired finish. Always refer to your machine and material guidelines.
5. Do I need to use coolant with this tool?
Yes, for best results and extended tool life, using mist or air blast coolant is recommended—especially when machining metals or running longer production cycles.
