The Widin Carbide Corner Radius End Mill is a high-performance cutting tool designed for machinists and engineers tackling hard materials with precision. With a 4 mm cutting diameter and a 0.3 mm corner radius, it delivers accurate corners and reliable fillets, while the long shank provides reach for deep grooves and tight pockets.

• Diameter x Radius: 4 mm cutting diameter with a 0.3 mm corner radius for precise corners and clean fillets.
• Flute Count: 4-flute geometry tuned for effective material removal and stable cutting.
• Long Shank: Extended shank enables access to deep grooves and hard-to-reach pockets.
• Material: Carbide construction delivers hardness, wear resistance, and longer tool life.
• Cutting Edge Geometry: Special high-strength edge design enhances cutting performance on tough workpieces.
• Application Focus: Ideal for deep groove milling, pocketing, and precise corner radii in high-hardness materials.
• Stability and Durability: Rigid geometry minimizes deflection and maintains consistent finishes under load.

The combination of a high-strength corner radius, four flutes, and a long shank makes this end mill a reliable choice for demanding milling tasks. Whether you’re shaping tight corners in hardened steels, machining precise fillets in molds, or finishing deep grooves in complex parts, this tool maintains accuracy, repeatability, and tool life across extended sessions.
