Why buyers pick this one
- Up to 70HRC Machining Power
- Forged from a meticulously formulated ultra-fine carbide matrix (HRC65 base), this end mill possesses the massive transverse rupture strength required to mill ultra-hard workpiece materials (55HRC to 70HRC) without premature chipping.
- Advanced HARDMAX Coating
- Features our high-performance HARDMAX coating, delivering unparalleled heat shielding and surface lubricity. It significantly reduces friction and prevents the immense heat of hard-milling from destroying the cutting edge.
- Versatile Flute Configurations (3/4/6)
- We offer unparalleled OEM flexibility. Choose a 3-flute or 4-flute design for aggressive material removal, or opt for our specialized 6-flute geometry to achieve ultra-fine, mirror-like finishing on hardened steel surfaces.
- 45° High Helix Angle
- The optimized 45-degree spiral geometry sharply reduces cutting resistance and minimizes spindle vibration, ensuring ultra-smooth chip evacuation during continuous heavy-duty processing.
- Limitless OEM Production
- Do not restrict your inventory to standard sizes. Our advanced CNC grinding facility is equipped to manufacture bespoke diameters, custom overall lengths, and apply specialized laser branding tailored exclusively for your business.
