Trending YG1 UGMG20016 1/4″ Size, 3/4″ LOC, 6 Flute, Y-Coating Solid Carbide Square End Mill

Unequal index reduces chatter for high speed & trochoidal milling

Applications

Measuring 1/4″ in diameter with a 3/4″ length of cut, the YG1 UGMG20016 solid carbide square end mill combines rigidity and reach for precise milling in steel and similar materials. Its 6-flute design and 45° helix angle, enhanced by Y-Coating, improve chip evacuation and surface finish while maintaining strength during high-feed operations. This tool supports efficient machining of steel, stainless steel, hard materials, and heat-resistant superalloys, providing versatility for demanding applications. The center-cutting geometry permits plunge cutting, expanding its utility in slotting and pocketing tasks. Without a corner radius, it produces sharp edges but requires careful feed control to avoid chipping during interrupted cuts. The Y-Coating is optimized for ferrous materials, resisting wear and reducing heat buildup to extend tool life. Avoid using this end mill on non-ferrous materials since the coating is poorly matched and will degrade rapidly; it is unsuitable for applications requiring corner radius or specialized coatings for non-ferrous metals. This tool is ideal for ferrous metals with moderate to high hardness, where a robust, sharp cutting edge is essential.
