DESCRIPTION

RC55 High-Hardness 2-Flute Ball Nose End Mill | D4*75 Extended Reach
This HRC55 2-flute carbide ball nose end mill is designed for high-precision machining with an extended reach. With a total length of 75mm, this tool is perfect for deep-cavity and deep-pocket milling on high-hardness materials.
Extended Reach for Deep Cavities: The longer 75mm length is ideal for reaching into deep pockets and tight spaces, eliminating the need for tool extensions and ensuring greater stability and rigidity during machining.
Precision Ball Nose Design: The D4mm ball nose tip is perfect for complex curved surface machining, arc slotting, and fine contouring, providing a smooth and precise finish on the workpiece.
2-Flute Structure for Smooth Chip Evacuation: The optimized 2-flute design provides a large chip space, preventing chip clogging and secondary cutting. This boosts machining efficiency and improves surface finish.
Designed for High-Hardness Materials: Made from high-quality carbide, this tool is tailored for materials up to HRC55. It effectively reduces tool wear and extends service life, making it a reliable choice for machining hardened steel and mold steel.
