Widin Carbide Corner Radius End Mill for Stainless & Exotics is a precision cutting tool engineered for tough metals. This 12 mm diameter, corner radius R0.3 end mill features four flutes and a variable helix to deliver smooth entry and exit cuts, reduced chatter, and reliable performance when machining stainless steels and other exotic alloys. The design's unequal index flutes enhance chip emission, helping heat build‑up stay low and producing a cleaner surface finish.

• Unequal index flutes for efficient chip control: Staggered flutes promote steady chip flow, minimize built‑up edge, and preserve tool life while delivering consistent surface quality on hard materials.
• Corner radius R0.3 for smoother edges: The precise 0.3 mm radius creates gentle transitions that reduce edge chipping and improve part geometry, even on demanding profiles.
• 4‑flute, variable‑helix design for stability: Balanced cutting forces and reduced vibration provide reliable cutting in high‑hardness alloys, helping you finish jobs faster with fewer reworks.

This end mill is designed to help professionals and serious hobbyists achieve dependable results in stainless and exotic metals. Its carbide hardness and thoughtful geometry translate into longer tool life, fewer tool changes on production runs, and a consistently smooth, true finish that supports tighter tolerances and better overall part quality.
