YG1 86579TC 5/16″ Size, 13/16″ LOC, 5 Flute, TiCN Solid Carbide Finishing End Mill Deal

Applications

Ideal for finishing operations in steel, the YG1 86579TC solid carbide end mill features a 5/16″ diameter and 13/16″ length of cut. Its 5-flute geometry paired with a 45° helix angle and TiCN coating ensures excellent surface finish and efficient chip evacuation, particularly in low carbon steels like 1018 and A36. This design minimizes vibration and extends tool life during light radial stock removal. The end mill’s geometry and coating combination enable smooth cutting not only in steel but also in non-ferrous, stainless steel, and cast iron materials, assuming coating compatibility is observed. With a single-end and center cutting capability, it supports plunge cuts and delivers enhanced rigidity for tight tolerance applications. It is important to avoid using this tool on heat-resistant superalloys (HRSA ISO S) due to the TiCN coatings unsuitability, which results in rapid degradation. Additionally, the lack of a corner radius means preventing edge chipping relies on proper feed rates and avoiding 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.
