Certified YG1 7555 5/16″ Size, 3/16″ LOC, 4 Flute, Bright Solid Carbide Finishing End Mill

Little to no coolant required with TiAlN Futura Coating!

Applications

The YG1 7555 finishing end mill features a 5/16″ diameter with a 3/16″ length of cut, creating a stub-length tool with a 0.6x length-to-diameter ratio that improves rigidity and precision in short-reach milling. It excels in profiling and finishing operations requiring tight tolerances and minimal deflection.
Combining a 30° helix angle, bright coating, and four flutes, this tool delivers sharp cutting edges with reduced friction, minimizing grabbing and heat buildup when machining free-machining non-ferrous metals such as brass and bronze. The bright coating supports smooth chip evacuation and surface finish, while the geometry balances efficient material removal with fine edge quality.
Coated end mills generally deliver better results on hard steels. Its design aligns with recommended uses for non-ferrous metals, particularly in detailed finishing and profiling applications. With no corner radius, chipping prevention depends on the sharpness and coating rather than edge rounding.

Features

• Possible for high-speed cutting, suitable for high efficiency machining for 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.
