Description
The Widin Carbide End Mill is a precision ball-nose cutter designed for hard materials. With a 4 mm diameter and a 70 mm overall length on a 6 mm shank, it’s ideal for engineers, shops, and hobbyists who need accurate contouring and smooth finishes in tough workpieces. The two-flute geometry helps keep cutting forces manageable and supports efficient chip evacuation for steadier cuts.
Engineered for dry cutting and high-speed machining, this end mill uses a newly developed carbide substrate and an advanced coating. The result is longer tool life, reliable performance in demanding applications, and higher productivity with every pass.
- Ball Nose Geometry for Smooth Contours: The 2-flute design delivers efficient material removal with less heat buildup, producing smooth, accurate 3D surfaces and gentle transitions on complex features.
- High-Hardness Capability up to HRc70: Specifically engineered to cut hardened steels up to HRc70, enabling reliable performance in demanding applications where other cutters struggle.
- Dry Cutting Ready with Advanced Coating: Optimized for dry cutting and high-speed machining, with a coating that reduces friction, cools during cutting, and extends tool life for longer production runs.
This combination translates to faster cycles, cleaner finishes, and fewer tool changes in tough production environments. The Widin end mill delivers consistent results across operations—from roughing to finishing—while maintaining precision and rigidity thanks to its robust 6 mm shank. Whether you're chasing tight tolerances on hardened components or finishing intricate contours, this cutter helps you complete projects on time with dependable quality.
