Niagara 40223 End Mill

Niagara 40223 is a four-flute, high-speed steel end mill with an 11/16" cutting diameter and a 5/8" shank, engineered for reliable general-purpose milling and profiling; the.06" corner radius provides precise edge definition and smooth contours in tight workpieces while preserving tool strength. The four-flute configuration supports efficient chip evacuation and added rigidity, enabling stable cuts in light- to medium-depth milling tasks and improving finish consistency on contouring and slotting operations. Made from high-speed steel, this Niagara end mill is designed for repeatable performance in standard metalworking scenarios, offering predictable results across typical milling jobs.
