The Widin Carbide Corner Radius End Mill is a high-performance cutting tool designed for professionals tackling hard materials and intricate pocketing tasks. Its long shank and precise corner radius deliver dependable precision in deep grooves and tight spaces.

• Diameter and corner radius: 8 mm diameter with a 0.5 mm corner radius (R0.5) to produce smooth, break-free edges and maintain accurate fillets.
• Flute count: 6-flute design for efficient material removal and a finer surface finish on hard metals compared to fewer-flute tools.
• Helix angle: 45° helix for balanced chip evacuation and reduced cutting forces, helping to minimize chatter.
• Long shank: Extended shank improves accessibility to deep pockets, grooves, and contours while preserving rigidity in steady cuts.
• Material: Solid carbide construction delivering high hardness capability, wear resistance, and longer tool life in demanding applications.
• Recommended uses: Deep groove machining, contouring, edging, and precision pocketing in tough materials and alloys.

What this means in practice: faster material removal with a smoother surface finish, reduced tool deflection in deep pockets, and durable performance under high-pressure cutting. The R0.5 corner radius preserves critical edges while reducing the risk of chipping on corners, making it ideal for finishing passes and precise filleting. The combination of 6 flutes and a 45° helix provides efficient chip clearance and stable cutting action, helping you achieve consistent tolerances and repeatable results across complex geometries.
