Widin Carbide Corner Radius End Mill is a 5.5 mm diameter cutting tool designed for mold and die manufacturing. Its 4-flute configuration and variable-index geometry deliver smoother cutting, efficient chip evacuation, and versatile corner radii (including R0.1), while the long shank provides extended reach for deep grooves and complex cavities.

• Variable index geometry for smoother cutting: The alternating edge distribution reduces cutting forces and chatter, improves chip evacuation, and helps achieve cleaner finishes and longer tool life.
• Long shank design for deep grooves: Provides extended reach and steady performance during deep slots and pockets, improving access without sacrificing rigidity.
• Corner radius versatility for mold features: Wide range of corner radii, including R0.1, to match fillets precisely and finish surfaces consistently, reducing tool swaps and rework.

With its combination of index-variable cutting edges, robust 4-flute stability, and a long reach, this end mill helps you speed up milling cycles, improve surface quality, and maintain reliability across challenging mold and die jobs. It supports consistent performance from roughing to finishing and gives you confidence preparing tight radii and deep cavities without frequent tool changes.
