Widin Carbide Corner Radius End Mill - 2 Flute Long Neck Back Draft Type - 3mm x8mm x R0.5

Widin's Carbide Corner Radius End Mill is a precision cutting tool crafted for demanding milling tasks. Designed for machinists and engineers who work with hard materials, this 2-flute, long-neck cutter delivers steady performance, clean edges, and reliable rigidity in a compact 3 mm cutting diameter.

• Cutting Diameter: 3 mm for precise detailing, pockets, and small-feature profiles.
• Neck Length: 8 mm long neck to reach into deeper grooves while maintaining rigidity.
• Corner Radius: R0.5 for smoother edges and reduced wear on both tool and workpiece.
• Flutes: 2 flutes with a 30° helix for efficient chip evacuation and balanced cutting forces.
• Center Cutting: Yes, enabling plunge milling and versatile entry methods.
• Material: Ultra-fine grain carbide delivering high hardness, wear resistance, and long tool life.
• Back Draft Design: Long-neck, back-draft geometry enhances stability and minimizes chatter on complex contours.
• Hardness Capability: Suitable for machining high-hardened materials up to HRc70, expanding its use into tough alloys and hardened steels.

This end mill is built to deliver consistent, accurate cuts in challenging applications. The combination of a small diameter, robust carbide, and a thoughtfully engineered geometry makes it ideal for profiling, slotting, and deburring hardened workpieces. Its design helps maintain dimensional accuracy across deep pockets and sloped surfaces, while the 30° helix promotes smooth chip flow and a clean finish. The Widin 3 mm corner-radius end mill is particularly well-suited for die/mold work, aerospace components, and other precision machining tasks where edge quality and tool life matter.
