Widin Carbide Corner Radius End Mill - 2 Flute Long Neck Back Draft Type - 0.4mm x2mm x R0.05

Meet the Widin Carbide Corner Radius End Mill — a high-precision cutting tool built for micro-machining, detailing, and deep-pocket work. Designed for engineers and precision-focused shops, it combines a tiny 0.4 mm diameter with a robust carbide body to deliver consistent, clean cuts on hard materials.

• Diameter: 0.4 mm cutting diameter for fine detail
• Flute count: 2 flutes for efficient chip control and smooth finishes
• Material: Ultra-fine grain carbide for exceptional rigidity and wear resistance
• Helix angle: 30° helix promotes effective chip evacuation and stable cutting
• Corner radius: R0.05 to produce smooth edges and reduce tool wear
• Center-cutting: Yes, enabling plunging and contouring in straight and curved paths
• Back draft & Long neck: Long neck with back-draft geometry for enhanced rigidity and reduced chatter
• Reach capability: Long reach suits deep grooves and sloped surfaces without compromising rigidity
• Material hardness: Designed to machine materials up to HRc70 for challenging applications
• Neck-length versatility: Neck length can be effectively adjusted with rake-angle changes for different operations

With this combination of precision geometry and durable carbide, you can expect tight tolerances, smooth edge finishes, and reliable tool life across demanding machining tasks. The 0.4 mm diameter supports intricate slots and micro-features, while the corner radius minimizes edge chipping and improves surface quality. The center-cutting design enables plunging, contouring, and pocket milling in a single tool, reducing tool changes. The back-draft long neck design reduces vibration during deep-depth cuts, helping you maintain accuracy in deep grooves and sloped faces. In practice, this end mill excels in aerospace components, medical instrumentation housings, electronics enclosures, and micro-mechanical assemblies where precision and durability are crucial.
