Description
The Widin Carbide Corner Radius End Mill is a precision cutting tool designed for mold and die manufacturing. With a 4 mm diameter and a tight R0.1 corner radius, it delivers repeatable, clean finishes in challenging cavities and grooves.
Built around a variable index and a 4-flute design, this end mill provides smooth cutting action and efficient chip evacuation while reducing cutting forces. Its long shank offers extended reach for deep groove machining, making it a versatile choice for complex molds and dies.
- Variable index geometry for smoother cuts: Optimizes edge distribution to lower load, improve chip clearance, and deliver cleaner surfaces with consistent tool performance.
- Long shank design for deep grooves: Provides extended reach into deep cavities and tight areas without compromising rigidity or stability.
- 4-flute carbide with precise corner radius R0.1: Ensures reliable performance and repeatable finishes across mold and die applications.
This end mill helps streamline mold and die workflows by delivering reliable, repeatable results, reducing downtime from tool changes, and enabling smoother tool paths. Its combination of corner radius, flute count, and long reach supports faster cycles, improved surface quality, and consistent part accuracy across a range of machining scenarios.
