Widin Carbide Corner Radius End Mill - 2 Flute Long Neck Back Draft Type - 1mm x20mm x R0.3

The Widin Carbide Corner Radius End Mill is a precision cutting tool designed for micro-machining tasks that demand clean radii and dependable performance. Built for machinists working with hard-to-cut materials, it delivers consistent, accurate cuts in tight pockets and deep slots.

• Diameter: 1 mm
• Neck length: 20 mm long neck for reach in deep grooves
• Corner radius: R0.3 for smooth edges and reduced wear
• Flutes: 2-flute design supports efficient cutting and chip evacuation
• Helix angle: 30° for efficient cutting and smoother chip flow
• Material: Ultra-fine grain carbide for high strength and long life
• Center cutting: Yes—enables plunging and pocketing with a single tool
• Back draft type: Long-neck, back-draft geometry for stability and reduced chatter
• Hardness capability: Suitable for machining hardened materials up to HRc70
• Application: Ideal for deep grooves, tight radii, and precision edge finishes

These design choices translate into real-world benefits: cleaner radii and smoother edges on delicate features, longer tool life when working with hard metals, and reduced vibration for steadier finishes in deep pockets and on sloped surfaces. The two-flute geometry and 30° helix pair with the long neck to deliver reliable chip evacuation and stable cutting, even when the geometry of the part demands close clearance. Use this end mill for pocketing, contour milling, and finishing operations in steels, alloys, and other hard materials up to HRc70, where precision and consistency matter most.
