While Supplies Last YG1 UGMF68905 1/4″ Size, 3/4″ LOC, 4 Flute, Y-Coating Solid Carbide Square End Mill

Special flute geometry & variable helix eliminate vibrations

Applications

The YG1 UGMF68905 solid carbide square end mill measures 1/4″ in diameter with a 3/4″ length of cut, offering a well-balanced reach and rigidity for precision milling in hard materials. Its 4-flute design, combined with a 36° helix angle and Y-Coating, improves chip evacuation and wear resistance, supporting both roughing and finishing in tool steels and nickel-based alloys. This combination reduces edge chipping and extends tool life under the stresses encountered during hardened steel machining. Supplied by Travers Tool, this tool is optimized for general milling of hardened steels within the 45-52 Rc range, where its geometry and coating work together to deliver consistent performance. While it lacks a corner radius, which requires monitoring for chipping during interrupted cuts, it benefits applications needing sharp corners for detailed features. Avoid using this end mill on non-ferrous materials as its Y-Coating will degrade rapidly and is unsuitable for soft metals or plastics.
