FAQ
Q1: What materials is this end mill best suited for?
A: Optimized for stainless steel (300 series), common steel, and cast iron. It excels at heavy rough cutting and semi-finishing of hard-to-machine materials.
Q2: What are the benefits of the corner radius design?
A: Reduces stress concentration at the cutting edge, prevents chipping, extends tool life, and enables precision fillet machining to enhance workpiece strength.
Q3: What are the core advantages of the TiAlCrN coating?
A: Provides exceptional high-temperature oxidation resistance and wear resistance, reducing tool wear and extending tool life in stainless steel machining.
Q4: Can this end mill be used for hardened steel (HRC>45)?
A: It is designed for materials up to HRC 45. For hardened steel (HRC 55–68), we recommend our HRC60/HRC68 series end mills for better performance and tool life.
Q5: What is the MOQ and lead time?
A: MOQ is 1pc, samples are available. Standard sizes: 7-15 days delivery; custom sizes: 15-25 days.
Q6: Are custom sizes or corner radii available?
A: Yes! We offer full customization of diameter, overall length, flute length, and corner radius to meet your specific tooling requirements.
