The Widin Carbide Corner Radius End Mill is a precision cutting tool designed for machinists tackling hard materials with tight radii and deep grooves. Its 4 mm cutting diameter and long shank—paired with a 0.1 mm corner radius and 2-flute geometry—deliver reliable, accurate results in confined spaces.

• Diameter: 4 mm cutting diameter designed for precise pockets and slots in hard materials.
• Corner Radius: R0.1 to create clean internal corners and improve wall finish in grooves and pockets.
• Flute Count: 2 flutes balance material removal with surface finish for tough workpieces.
• Material: Carbide construction delivers high hardness, wear resistance, and stable performance under demanding cuts.
• Shank: Long shank provides extended reach for deep grooves, recesses, and machining in confined spaces.

With this end mill, you gain reliable radii and cleaner walls on high-hardness workpieces such as hardened steels and stainless alloys. The combination of carbide hardness, a precise R0.1 edge, and a long reach reduces tool deflection and setup time, enabling you to finish deep grooves and pockets in fewer passes. Ideal for toolmakers, job shops, and OEMs, it supports precise finishing, consistent geometry, and efficient workflows in challenging milling tasks.
