FAQ
What materials can this end mill cut?
The mill is optimized for carbon steel, alloy steel, stainless steel, and high‑hardness alloys up to HRC60, making it suitable for most industrial applications.
How does the NACO coating improve performance?
NACO coating enhances oxidation resistance, high‑temperature stability, and wear resistance, allowing the tool to maintain sharpness longer under demanding cutting conditions.
Is this mill compatible with standard CNC collets?
Yes, the 1/8 inch shank fits standard 1/8 inch collets used in most desktop and industrial CNC machines. Ensure the collet size matches the shank for optimal grip.
Can I use this mill for deep slotting?
While the flute length is 3/8 inch, the tool performs well for shallow to moderate depth slotting. For deeper cuts, consider multiple passes or a longer‑flute variant.
What is included in the package?
Each package contains five square nose end mills, each individually sealed in a plastic storage box to protect against damage and contamination.
