Widin Carbide Corner Radius End Mill For Stainless & Exotics - 4 Flute Variable Helix - 8mm x R1.5

The Widin Carbide Corner Radius End Mill is a precision cutting tool designed for stainless steels and exotic alloys. With an 8 mm cutting diameter and a corner radius of 1.5 mm (R1.5), this 4-flute end mill uses a variable helix to promote smooth cutting, efficient chip evacuation, and reduced vibration. It’s built for engineers, machinists, and hobbyists who demand reliable performance on tough materials, delivering clean corners and consistent surface finishes in a single pass.

• Unequal index flutes for better chip control: The unequal flute spacing promotes efficient chip emission and contributes to a smoother workpiece surface finish on challenging materials.
• Wear-resistant carbide edge: High-hardness cutting edge delivers excellent wear resistance, helping you achieve longer tool life and reliable performance in demanding applications.
• Corner radius versatility: Designed around an 8 mm diameter with a 1.5 mm corner radius (R1.5), with options for other radii to match various fillet requirements across projects.

By combining controlled chip flow, a durable cutting edge, and flexible corner radii, this end mill supports faster, more consistent production of precise fillets and high-quality finishes on stainless and exotic materials. It helps reduce downtime, improve throughput, and deliver dependable results across a wide range of machining tasks.
