Engineered for precision micro‑machining, the Widin Carbide Corner Radius End Mill is built for toolmakers and CNC operators who demand consistent edge quality and reliable stability in tough materials. This 0.3 mm diameter, 2‑flute micro end mill features a long neck and back‑draft geometry to deliver controlled cuts in tight pockets, deep grooves, and angled surfaces.

• Diameter: 0.3 mm
• Flutes: 2‑flute design for efficient chip evacuation and stable cutting
• Corner Radius: R0.05 for smooth edges and reduced wear on workpieces
• Material: Ultra‑fine grain carbide delivering high strength and long tool life
• Helix: 30° helix supports effective chip control and surface finish
• Center Cutting: Yes, enabling plunging, pocketing, and finishing in a single tool
• neck Design: Long neck with back‑draft geometry for improved rigidity and reduced vibration
• Back Draft: Minimizes chatter in deep grooves and on sloped surfaces
• Hardness Capability: Suitable for machin­ing high hardened materials up to HRc70
• Neck Length Flexibility: Neck length effectively adjustable through rake angle considerations for versatile operation

This end mill is designed to deliver consistent radii and precise finishes across challenging materials and geometries. The combination of a small diameter with a long neck and back‑draft geometry helps maintain stability, reduces tool vibration, and minimizes chattering even in deep or inclined cuts. The result is accurate, repeatable performance, longer tool life, and smoother edges in micro‑pocketing, deburring, and finishing tasks. Ideal for micro manufacturing, watchmaking, electronics housings, and aerospace component prototyping where tight tolerances matter.
