Widin's Carbide Corner Radius End Mill is a precision cutting tool designed for machinists who need clean edges, deep-pocket capability, and reliable performance on hard materials. With a 3 mm diameter, 16 mm cutting length, and a corner radius of R0.3, this 2-flute end mill combines a long neck and back-draft geometry to deliver stable, accurate cuts in challenging profiles.

• Diameter: 3 mm
• Cutting length: 16 mm
• Corner radius: R0.3
• Flutes: 2
• Helix angle: 30°
• Material: Ultra-fine grain carbide
• Neck geometry: Long neck with back draft for increased rigidity
• Center cutting: Yes
• Chip evacuation: Efficient for clear chips and smooth finishes
• Hard material capability: Suitable for high-hardened materials up to HRc70

The tool is engineered to deliver consistent performance across demanding applications. The center-cutting design enables plunging and slotting in a single pass, while the 2-flute geometry promotes efficient chip clearance and productive cutting speeds. The long neck and back-draft geometry reduce vibration and chatter, helping you maintain precise profiles in deep grooves, pockets, and sloped surfaces. Made to handle very hard materials, this end mill expands your capabilities in moldmaking, automotive components, and precision engineering tasks. For best results, optimize feeds and speeds to match material hardness and desired surface finish, and apply appropriate cooling or lubrication to maximize tool life.
