Widin Carbide Corner Radius End Mill is a precision milling tool designed for engineers and machinists who demand clean, accurate finishes in tight tolerances. This 12 mm diameter, 80 mm long end mill features a 3.0 mm corner radius and a four-flute configuration engineered for demanding precision milling tasks.

- Diameter × Length: 12 mm diameter, 80 mm overall length for reach in pockets and contours.
- Corner Radius: R3.0 radius to create smooth fillets and minimize edge damage on workpieces.
- Flute Count: 4-flute configuration balances precise cutting with efficient chip evacuation.
- Cutting Edge Design: Straight flute geometry enhances rigidity and reduces corner deformation during cuts.
- Edge Technology: Back Draft Type cutting edge helps dampen movement and suppress chatter for smoother operation.
- Material: Carbide substrate delivers hardness and wear resistance for durable performance in metalworking.
- Ideal Applications: Suitable for precision milling, pocketing, contouring, and deburring in various metals.
With its straight flute design and Back Draft edge, this end mill delivers stable cutting, lower vibration, and improved surface finishes. The corner radius helps preserve workpiece integrity by reducing edge chipping, while the stub cut length adds rigidity in shallow passes for better control and repeatable results. Built on a carbide foundation, it stands up to demanding materials, making this tool a reliable choice for high-precision machining workflows.
