Description
The Widin Carbide Corner Radius End Mill for Mold & Die is a versatile 3.5 mm diameter cutting tool designed for mold makers, die shops, and advanced hobbyists who need precise corner radii and reliable performance. Its variable index combined with a 4-flute design delivers smooth cuts, reduced cutting forces, and efficient chip evacuation across a range of materials and complex geometries.
With a long shank for extended reach into deep grooves and pockets, this end mill accommodates challenging mold and die features. A broad range of corner radii, including R0.3, lets you tailor the tool to your exact geometry without swapping tooling, improving workflow and reducing downtime.
- Variable index geometry for smoother cutting: The variable index design distributes cutting edges more evenly, reducing vibration and cutting forces to produce cleaner finishes and extend tool life through better chip control.
- 4-flute design for efficient material removal: This configuration offers a strong, rigid cut with excellent chip clearance, delivering consistent surface finishes and reliable performance across materials encountered in mold and die work.
- Long shank with versatile corner radii: The extended reach handles deep grooves and tight pockets with stability, while the available corner radii (including R0.3) provide precise rounding to match mold and die specifications.
Designed to improve accuracy and productivity, this end mill helps you achieve repeatable radii and smooth surfaces with fewer passes. Its combination of efficient chip evacuation, stable cutting action, and flexible radius options makes it a dependable choice for demanding mold and die applications, enabling quicker setups, fewer tool changes, and higher-quality results.
