Meet the Widin Carbide Corner Radius End Mill—a compact, high-precision cutting tool engineered for machining high-hardness materials. With a 1 mm diameter, R0.2 corner radius, and a long shank, it’s ideal for deep grooves, slots, and tight spaces where accuracy matters.

• Diameter: 1 mm cutting diameter designed for precise, small-scale milling and fine feature definition.
• Corner radius: R0.2 at the tip to preserve sharp internal corners and minimize chipping when working with tough materials.
• Flute count: 2-flute design that promotes efficient chip evacuation and stable cutting at small diameters.
• Material: Carbide construction delivers superior hardness and wear resistance for longer tool life in demanding jobs.
• Shank length: Long shank provides extended reach for deep grooves, recessed features, and hard-to-access areas.
• Cutting geometry: Optimized edge geometry and helix for smooth cuts and good surface finish on high-hardness workpieces.
• Applications: Well-suited for hardened steels and other high-hardness alloys, enabling precise micro-milling and intricate internal features.

This end mill’s design focuses on delivering consistent performance where it counts—tight corners, deep pockets, and confined spaces. The combination of carbide rigidity, a small-diameter bit, and a purposeful corner radius helps you achieve clean edges, maintain tight tolerances, and reduce setup changes during multi-step machining. The long shank expands your capabilities for deep grooves and complex geometries without compromising stability or finish quality.
