The Widin Carbide Corner Radius End Mill is a precision milling tool crafted for machinists who work with hard metals. With a 4 mm diameter, stub-cut length, and an exact R0.2 corner radius, it delivers clean corners and dependable performance in tight pockets.

• Flute Count: 4 flutes for efficient material removal and a refined finish on hard workpieces.
• Cutting Length: Stub-cut length enhances rigidity and minimizes deflection in shallow pockets and slots.
• Diameter: 4 mm, compatible with standard CNC collets and holders.
• Overall Length: 25 mm, offering a compact reach with solid rigidity.
• Corner Radius: R0.2 for precise internal corners and smooth radii in contours.
• Material: Carbide construction delivers exceptional hardness, wear resistance, and longer tool life.
• Application Focus: Optimized for high-hardness workpieces and a broad range of metals and alloys.

With this end mill, you can achieve accurate corner radii in pockets, slots, and fillets on tough materials, reducing tool deflection and improving part accuracy. The 4-flute geometry balances material removal and surface finish, while the carbide construction withstands aggressive machining, helping you complete jobs faster and with fewer tool changes. For best results, pair with appropriate feed rates and coolant to manage heat and extend tool life—especially when working with hardened steels or tough alloys.
