Seasonal Sale YG1 UGMF68907 3/8″ Size, 7/8″ LOC, 4 Flute, Y-Coating Solid Carbide Square End Mill

Special flute geometry & variable helix eliminate vibrations

Applications

Featuring a 3/8″ diameter and 7/8″ length of cut, the YG1 UGMF68907 solid carbide end mill offers a balanced combination of reach and rigidity tailored for precision milling in hard materials. Its 4-flute design paired with a 36° helix angle and Y-Coating creates an effective cutting geometry excelling in general milling of hardened steels, tool steels, and nickel-based alloys. This synergy reduces cutting forces and enhances chip evacuation, thereby improving tool life during roughing and light high-efficiency milling applications. Designed to machine hardened steels in the 45-52 Rc range, it supports both roughing and finishing operations on walls and floors. The lack of a corner radius optimizes it for square shoulder milling, with less concern for chipping during interrupted cuts. Avoid this end mill for non-ferrous materials, as the Y-Coating is not a good match and will deteriorate quickly; its design focuses on hard and ferrous materials exclusively.
