1. What is the 1mm endmill typically used for?
The 1mm endmill is commonly used for precision CNC milling in small parts, fine slotting, engraving, and contouring applications across industries like electronics, mold-making, and precision engineering.
2. Is the 1mm endmill suitable for hard materials like stainless steel?
Yes, the tool’s solid carbide construction and wear-resistant coating make it ideal for machining stainless steel, alloy steel, and even some hardened materials with proper cutting parameters.
3. What are the benefits of the 4-flute design in this tool?
The 4-flute geometry provides a smoother surface finish, better tool rigidity, and efficient chip evacuation—especially useful in harder materials or when tighter tolerances are required.
4. What is the recommended spindle speed for a 3mm coated endmill?
Spindle speeds typically range from 15,000 to 25,000 RPM depending on the material and depth of cut. Always refer to specific cutting data for optimal results.
5. Do I need to use coolant while machining with this endmill?
Yes, using coolant or air blast is advisable to reduce heat, prevent tool wear, and improve surface finish, especially during long or high-speed operations.
