Description

The Widin Carbide Corner Radius End Mill is a precision milling tool built for engineers and machinists who demand clean, accurate corners and dependable performance. This 8 mm diameter, 100 mm overall length end mill features a 2.0 mm corner radius and a 4-flute straight-flute design for enhanced rigidity and control.

  • Diameter: 8 mm
  • Overall length: 100 mm
  • Cutting length: Stub-cut length for added rigidity and precise engagement
  • Corner radius: R2.0 (2.0 mm) for durable, well-defined corners
  • Flute count: 4 flutes
  • Flute type: Straight flute design to maximize rigidity and minimize corner damage
  • Special edge: Back Draft Type cutting edge reduces chattering and promotes smoother cuts
  • Material: Carbide for high hardness and wear resistance

This end mill is designed to deliver clean finishes and tight tolerances across precision machining tasks. The straight flute combined with a stub-length geometry provides superior rigidity, helping you maintain accuracy at higher feeds and depths. The Back Draft Type edge minimizes vibration and movement, resulting in better surface quality and longer tool life. With a 2.0 mm corner radius, you can achieve smooth, reliable radii on pockets, contours, and profiles while reducing edge chipping and deflection. Ideal for precision milling in metalworking applications, prototypes, and production runs where repeatable, high-quality results matter.
