Description
Widin Carbide End Mill is a ball-nose milling cutter designed for precise curved features in demanding materials. With a 2 mm cutting diameter, 50 mm length of cut, and a 4 mm shank, it’s a compact, capable choice for engineers, machinists, and hobbyists who need reliable contouring and smooth finishes on tough metals.
Designed for dry cutting and high-speed machining, it uses a newly developed raw material and an advanced coating to maximize wear resistance and productivity. The two-flute design promotes rapid chip evacuation and reduced cutting forces, delivering consistent, high-quality results in hard alloys.
- Hard-material capability up to HRc70: Engineered to cut hardened steels and other tough alloys with predictable wear and reliable tool life, enabling consistent results on demanding parts.
- Ball-nose geometry for smooth contours: Produces clean radii and gentle transitions for 3D profiles, fillets, and engraving with minimal chipping and excellent surface finish.
- Two-flute design for efficient chip evacuation: Larger flute space clears chips quickly, reduces heat buildup and cutting forces, and supports smoother cuts and longer tool life.
Using this end mill helps you complete complex, high-precision features on hard materials with fewer passes, improved surface quality, and tighter tolerances. The combination of hard-material capability, refined geometry, and durable coating translates to faster setups, less downtime, and more consistent results across production runs.
