❓ Frequently Asked Questions
1. What is the benefit of the Nano Coating on these ball nose end mills? The Nano Coating provides superior hardness (up to 4300 HV) and extreme heat resistance (up to 1200°C), allowing for high-speed cutting and longer tool life even in dry machining conditions.
2. Can these tools handle high-hardness steel? Yes, our HRC65 grade tools (made with Sandvik H10F raw material) are specifically designed to process tempered steel, mould steel, and other materials with hardness up to 65 HRC.
3. Do you offer OEM or custom size services? Yes, we provide OEM services. While we have a wide range of standard sizes from 1mm to 20mm, we can support specific requirements based on your machining needs.
4. What materials are these end mills most suitable for? These end mills are optimized for carbon steel, mould steel, stainless steel, and alloy steel. They are ideal for high-precision finishing operations.
5. Why are 2 flutes preferred for ball nose end mills? 2 flutes provide excellent chip clearance, which is critical during contouring and pocketing operations where the tool tip has a smaller diameter. This prevents chip clogging and ensures a smoother surface finish.
6. What is the raw material origin? We use 100% new materials, including high-grade carbide from Germany (K44/K40) and Sandvik (H10F), ensuring consistent quality and performance.
