Deal YG1 85579TC 5/16″ Size, 7/16″ LOC, 5 Flute, TiCN Solid Carbide Finishing End Mill

Applications

The YG1 85579TC finishing end mill measures 5/16″ in diameter with a 7/16″ length of cut and features 5 flutes with a TiCN coating, designed for rigidity and precision in a stub length format. Its 45° helix angle and flute count optimize surface finish and chip evacuation when machining steel and similar materials. This size and flute configuration improve stability during finishing passes, reducing vibration and enhancing dimensional accuracy. Paired with TiCN coating, the high flute count and steep helix angle promote smooth cutting and wear resistance in low carbon steel, while also extending usability to non-ferrous, stainless steel, and cast iron materials. The geometry aligns with recommended finishing applications for low carbon steel, prioritizing light radial stock removal and surface quality. Avoid using this tool on heat-resistant superalloys (HRSA ISO S), as the TiCN coating is not well matched and will degrade rapidly. Its lack of a corner radius means that edge chipping prevention depends on proper feed rates and avoidance of interrupted cuts.

Features

• Designed to machining stainless steel, inconels and other alloys.
• The new design of stub length allows cutting at maximum speeds and feeds with minimum deflection.
• 5 Flute and 45 degree medium helix allow harmonic balance and smooth cutting.
