Special Offer YG1 33564TC 11/64″ Size, 5/16″ LOC, 4 Flute, TiCN Solid Carbide Finishing End Mill

Applications

The YG1 33564TC solid carbide finishing end mill, sized at 11/64″ with a 5/16″ length of cut and four flutes, provides a rigid and precise tool designed for machining operations requiring a stub length-to-diameter ratio of about 1.82. This size offers excellent control and stability during finishing passes on steel and related materials. Its 30° helix angle combined with a TiCN coating and four-flute geometry achieves a balance between chip evacuation and surface finish quality, making it suitable for general milling of free-machining steel and similar alloys. The synergy between the tool’s geometry and coating reduces edge chipping and wear during finishing, especially in steels and cast irons. The four-flute design promotes smooth cutting action and consistent chip load, enhancing surface integrity. This combination matches recommended practices for free-machining steel, ensuring reliable performance in profiling and finishing tasks. Avoid using this end mill on heat-resistant superalloys (HRSA ISO S) due to coating unsuitability, which could cause rapid degradation. Applications requiring corner radius features should also be avoided, as this tool has sharp corners that do not specifically prevent chipping in interrupted cuts.

Features

• Suitable for cutting hardened & high alloy steels, steel casting, chill casting, malleable cast iron, CrNi-steels, brass, copper, aluminum with a high percentage of silicon and abrasive plastics.
