YG1 86579TH 5/16″ Size, 13/16″ LOC, 5 Flute, Hardslick Solid Carbide Finishing End Mill Limited Time

Applications

Designed for precision finishing in stainless steel and heat-resistant superalloys, the YG1 86579TH solid carbide end mill features a 5/16″ diameter and 13/16″ length of cut with 5 flutes. Its 45° helix angle and Hardslick coating facilitate smooth chip evacuation and vibration reduction, resulting in improved surface finish and extended tool life during high-speed machining. The combination of the Hardslick coating with the tools geometry enhances wear resistance and cutting efficiency in demanding materials like stainless steel and HRSA. The absence of a corner radius concentrates cutting forces on sharp edges, requiring careful feed rate management to prevent chipping, which supports detailed work. This end mill is not recommended for steel (ISO P) or non-ferrous materials due to coating unsuitability that can cause premature wear or failure. Its design is ideal for finishing applications where fine surface quality is essential rather than heavy stock removal or roughing.

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.
