The Widin Carbide Corner Radius End Mill is built for precision milling in demanding materials, offering a compact 3 mm diameter with a long neck and robust center-cutting performance for versatile, accurate cuts.

• Diameter: 3 mm
• Neck length: 8 mm long neck for reach into deeper pockets
• Corner radius: R0.2 for smooth edges and reduced edge wear
• Flutes: 2 flutes
• Helix angle: 30° for efficient chip evacuation and stable cutting
• Back draft design: Long neck with back draft provides enhanced rigidity and reduced vibration
• Center cutting: Yes, enabling plunging and versatile cutting approaches
• Material: Ultra-fine grain carbide for strength and durability
• Recommended hardness: Suitable for machining materials up to HRc70
• Application focus: Deep grooves, sloped surfaces, radii finishing, and edge preparation in hard alloys

This end mill is designed to deliver precise radii and clean edges in tough materials without excessive chatter. The combination of a long neck and back draft helps maintain stability during deep cuts, while the 2-flute geometry supports efficient material removal and smooth surface finishes. With center-cutting capability and a small diameter, it excels in tight pockets and intricate contours, making it a reliable choice for tool steels, hardened steels, and other high-hardness workpieces. Use in appropriate CNC milling setups and maintain proper rigidity and lubrication to maximize tool life and finish quality.
