Advantages and Features
Low Vibration
● Unequal flute spacing and variable helix angles reduce vibration.
● Large core diameter ensures high rigidity and prevents chatter.
Chipping Resistance
● Cutting edge protection prevents chipping.
Versatility
● Suitable for roughing, finishing, and semi-finishing, delivering excellent performance across various machining processes.
● Compatible with carbon steel, alloy steel, pre-hardened steel, and tool steel (HRC ≤ 45).
Nano-coating
● Heat-resistant, oxidation-resistant, and wear-resistant.
● Lowers the friction coefficient, reduces cutting heat, and prevents built-up edge (BUE) formation.
