Widin Carbide Corner Radius End Mill - 2 Flute Long Neck Back Draft Type - 0.8mm x4mm x R0.1

The Widin Carbide Corner Radius End Mill is a precision cutting tool designed for engineers and machinists tackling hard materials and tight tolerances. With a 0.8 mm diameter, 4 mm cutting length, 2 flutes, and a precise corner radius, it delivers clean edges and reliable performance in challenging applications.

• Diameter: 0.8 mm
• Flutes: 2
• Corner Radius: R0.1 for smooth edges and reduced wear
• Helix Angle: 30° for efficient chip evacuation
• Cutting Length / Neck: 4 mm cutting length with a long neck for deep pockets
• Back Draft: Long-neck back-draft design to improve stability and reduce chatter
• Center Cutting: Yes — capable of plunging operations
• Material: Ultra-fine grain carbide for high rigidity and wear resistance
• Hardness Capacity: Suitable for machining materials up to HRc70
• Neck Length Adjustability: Effective neck length adjustments based on rake angle for versatile operation

This end mill is built for precision, offering a combination of strength, stability, and versatility. The small 0.8 mm diameter excels at fine detailing and delicate features, while the corner radius and center-cutting ability ensure smooth, accurate edges even in deep grooves or on sloped surfaces. The long neck and back-draft design minimize tool vibration, helping you achieve consistent finishes across complex geometries. With the capability to machine high-hardened materials up to HRc70, it’s a reliable choice for aerospace components, mold and die work, and precision tooling where durability and accuracy matter most.
