DESCRIPTION

Product Detail：

This HRC55 2-flute carbide ball nose end mill represents the pinnacle of hard milling technology. It is expertly engineered to deliver exceptional surface finish and extended tool life when machining the toughest materials.

• Uncompromising Performance on Hardened Steel: Designed specifically for materials with a hardness up to HRC55, this tool maintains its edge integrity and geometry in demanding applications. Its robust structure ensures minimal deflection and chatter, allowing you to achieve the highest standards of precision and surface quality on mold steels and hardened alloys.

• Precision Ball Nose Geometry: The advanced ball nose design is optimized for 3D contouring and complex curved surface machining. It minimizes step-over marks and guarantees a consistently smooth and accurate profile, crucial for final part quality in the mold and die industry.

• Built-in Efficiency: The 2-flute structure is specifically tailored for hard milling, providing maximum core rigidity and efficient heat dissipation. This design ensures superior chip evacuation and prevents thermal stress, allowing for higher cutting speeds and feed rates.
