The Widin Carbide Corner Radius End Mill is a precision cutting tool designed for stainless steels and other exotic alloys. It features a 16 mm cutting diameter with a 3.0 mm corner radius, delivering consistent interior radii and smooth surface finishes on hard-to-machine materials.

Four flutes combined with a variable helix provide excellent chip emission and stable cutting, helping you achieve reliable finishes even on challenging alloys. Crafted from durable carbide, this end mill is built for long tool life in demanding applications, making it a trusted choice for engineers, fabricators, and serious hobbyists.

• Unequal index flutes for efficient chip evacuation: The staggered flute spacing promotes smoother cutting and helps prevent chip buildup, resulting in cleaner finishes and cooler operation on stainless and exotic materials.
• High-hardness carbide edge for wear resistance: A sharp, durable cutting edge withstands repeated use in tough alloys, reducing frequent tool changes and maintaining consistent performance over time.
• Multiple corner radius options for precise finishes: Available with various corner radii to match part geometry, enabling accurate radii, improved edge strength, and reliable deburring in a single tool.

Designed to streamline your workflow, this end mill delivers repeatable radii, smoother surfaces, and longer service life. It’s a dependable addition to any setup—from CNC mills in production environments to hands-on shops— helping you complete parts faster with predictable, high‑quality results.
