Meet the Widin Carbide Corner Radius End Mill — a precision micro-milling tool designed for machinists and shops that demand exacting edges and dependable performance in hard materials. This 2-flute long-neck back-draft end mill combines a compact 1 mm diameter with a 6 mm cutting length and a precise R0.3 corner radius to deliver smooth, repeatable finishes on small features and tight pockets.

• Diameter: 1 mm
• Cutting length: 6 mm
• Corner radius: R0.3
• Flutes: 2-flute geometry
• Helix angle: 30° for efficient chip evacuation
• Neck design: Long neck for extended reach into deep grooves
• Back draft: Back-draft Type to boost stability and reduce chatter
• Center cutting: Yes — capable of plunging and pocketing
• Material: Ultra-fine grain carbide for strength and wear resistance
• Hardness capability: Suitable for machining high-hardened materials up to HRc70

This end mill is purpose-built for precision work: the corner radius minimizes edge wear and creates smoother transitions on finished parts, while the long neck and back-draft geometry maximize rigidity and control in challenging setups. The 30° helix supports efficient chip removal, reducing heat build-up and maintaining dimensional accuracy even in deep slots or on sloped surfaces. Use cases include micro-grooving, fine slotting, and finishing operations on hardened steels, tool steels, and other demanding materials. The neck length adjustability based on rake angle adds practical versatility for a range of milling operations without compromising stability.
