Solid Carbide Endmill 4 Flute Corner Radius
Radiused corner end mill for roughing and finishing of hardened steels, with strengthened cutting edges for reduced chipping and extended tool life. The corner radius geometry eliminates the sharp 90-degree corner found on square end mills, significantly reducing edge chipping in demanding machining applications. Available in 0.5mm, 1.0mm, and 2.0mm radius options.

Solid Carbide 4 Flute Corner Radius End Mills
Solid carbide 4 flute corner radius end mills combine the capabilities of square end mills with strengthened cutting edges for improved tool life in hardened and abrasive materials. The radiused corner distributes cutting forces over a larger area, reducing stress concentration and edge chipping during roughing and finishing operations.
Available with 0.5mm, 1.0mm, and 2.0mm corner radii in standard and variable helix configurations. Premium AlTiN and TiSiN coatings provide thermal protection for high-speed machining. Ideal for hardened tool steels, die steels, stainless steels, and high-temperature alloys where edge strength is critical.
