Description
The Widin Carbide Corner Radius End Mill is a precision cutting tool designed for stainless steels and exotic alloys. With a 10 mm cutting diameter, a 1.5 mm corner radius (R1.5), and a 4-flute, variable-helix geometry, this end mill delivers reliable performance in challenging materials.
Its corner radius enables accurate contouring and reduces the risk of chipping or fracturing on delicate features, yielding superior surface finishes. The carbide construction provides exceptional wear resistance, so tool life lasts longer even under demanding milling conditions.
- Efficient chip evacuation with 4-flute variable helix: The multi-flute, staggered geometry promotes steady chip flow and reduced heat buildup, helping maintain cutting stability and clean finishes in stainless and exotic alloys.
- Corner-radius for precise contouring and durable finishes: The R1.5 radius supports accurate profiling while minimizing corner fractures, producing smoother transitions and repeatable geometry on complex parts.
- Durable carbide construction for long tool life: Hardened carbide offers superior wear resistance and edge retention, reducing tool changes and downtime in tough milling applications.
Designed to boost productivity, this end mill helps you achieve consistent, high-quality results across a range of demanding tasks—from pocketing and profiling to finishing intricate contours—while providing reliable performance and extended tool life.
