Description

Widin Carbide Corner Radius End Mill is a precision micro-cutting tool designed for hard-material machining and fine edge finishing. It’s built for engineers and machinists who need repeatable, high-precision results in deep grooves, pockets, and small-radius features.

  • Diameter: 0.30 mm
  • Cutting Length: 1.00 mm
  • Corner Radius: R0.05
  • Material: Ultra-fine grain carbide for exceptional strength and wear resistance, suitable up to HRc70
  • Flutes & Helix: 2 flutes with a 30° helix for efficient chip evacuation and smooth cutting
  • Center-Cutting: Yes, enabling both plunge milling and conventional operations
  • Geometry: Long neck and back-draft design to boost rigidity, reduce vibration, and minimize chatter
  • Neck Length Versatility: Neck length adapts with rake angle to access deeper features without sacrificing stability

The combination of micro-diameter cutting, corner radius, and a long-neck, back-draft geometry delivers precise, repeatable finishes on challenging workpieces. The 2-flute, center-cutting design supports both plunging and contouring applications, while the R0.05 corner radius helps create smooth edges that resist chipping during high-precision tasks. Engineered from ultra-fine grain carbide, this end mill maintains sharpness and edge integrity even when machining hard materials up to HRc70, enabling reliable performance in micro-machining, electronics housings, medical components, and aerospace fixtures. For optimal results, match feed rates and spindle speeds to the material hardness and feature depth, leveraging the long neck to reach tight areas without compromising rigidity.
