Widin Carbide Corner Radius End Mill is a precise, durable cutting tool designed for machinists and engineers tackling hard metals and high-hardness workpieces. Its 4-flute, stub-cut geometry emphasizes rigidity and clean finishes, delivering reliable performance when you need sharp corners or smooth radii.

• Diameter: 4 mm cutting diameter for precise pocketing and contouring
• Length: 12 mm cutting length with a stub-cut design for rigidity and reduced tool deflection
• Flutes: 4-flute configuration for efficient chip evacuation and smoother surfaces
• Corner Radius: R0.5 mm to create accurate corner radii and controlled fillets
• Material: Carbide (tungsten carbide) construction for hardness and longer tool life
• End Mill Type: Stub-cut end mill that minimizes vibration during aggressive milling
• Applications: Ideal for hard metals, stainless steel, titanium alloys, and hard aluminum alloys in pockets, contours, and finishing passes

With this end mill, you gain consistent corner accuracy, reduced tool deflection, and efficient material removal. The combination of carbide hardness and a compact cutting length enables stable cutting at higher feed rates while maintaining surface quality. Use with appropriate speeds and feeds and coolant to maximize tool life and achieve tight tolerances on challenging materials.
