Widin Carbide Corner Radius End Mill - 2 Flute Long Neck Back Draft Type - 0.8mm x4mm x R0.2

The Widin Carbide Corner Radius End Mill is a precision cutting tool engineered for hard metals and detailed micro-machining. Designed for engineers, machinists, and demanding applications, it delivers smooth edges, reliable stability, and deep-pocket reach in a single, versatile end mill.

• Diameter and flute count: 0.8 mm diameter with a 2-flute design for clean, precise passes
• Cutting length and neck: 4 mm cutting length with a long neck for reach into tight or deep areas
• Corner radius: R0.2 corner radius to produce smooth edges and reduce edge wear
• Material: Ultra-fine grain carbide for exceptional rigidity and durability under high-load cutting
• Helix angle: 30° helix for efficient chip evacuation and stable cutting
• Back draft geometry: Long-neck back draft design enhances rigidity and minimizes chatter during operation
• Centre cutting: Centre-cutting capability enables plunging and versatile milling approaches
• Hard-material capability: Suitable for machining high-hardened materials up to HRc70, expanding machinability on tough steels and alloys

This end mill is built to deliver consistent performance across challenging machining tasks—from deburring and finishing micro-features to forming precise radii on raised sections. The combination of a compact 0.8 mm diameter with a robust carbide core supports fine detail work while handling the demands of hard materials. The long neck and back draft geometry minimize tool deflection and vibration, helping you achieve accurate depths and clean finishes even in deep grooves or on inclined surfaces. Its centre-cutting capability adds versatility for plunging operations, making it a go-to choice for high-precision milling where edge quality and dimensional stability matter most.
