Description
The Widin Carbide Radius End Mill is a high-performance cutting tool designed for precision machining. With four flutes and a long shank, it delivers deeper reach and added rigidity, making it ideal for deep cavities, contouring, and profiling across a wide range of materials.
Crafted from carbide for exceptional durability and wear resistance, this end mill handles both ferrous and non-ferrous alloys with confidence. Its radius end geometry enables smooth, accurate corners and clean profiles, while the four-flute design promotes efficient chip evacuation and steadier cutting for a superior surface finish and longer tool life.
- 3 mm cutting diameter with a 0.2 mm radius: precisely formed corners and tight radii for accurate pockets and contours, delivering consistent results in small-feature work.
- Four-flute design for efficient cutting: more cutting edges remove material quickly, improve finish, and enhance chip evacuation, reducing heat and enabling longer tool life.
- Long 4 mm shank for reach and rigidity: extended reach allows deeper pockets without losing stability, while the thick shank minimizes deflection for cleaner cuts and tighter tolerances.
This tool helps you complete tight-radius features with confidence, improves workflow through faster material removal and smoother finishes, and delivers durable performance that stands up to demanding production schedules. Whether you’re manufacturing prototypes, performing precision machining, or producing high-volume parts, the Widin Radius End Mill is designed to help you achieve repeatable, high-quality results.
