External Retaining Ring: 0.382" Groove Dia, 13/32" Shaft Dia, 15-7 Beryllium Copper & Stainless Steel, Zinc-Plated MPN:SH-40SS

The solid carbide square end mill offers superior strength and resistance to heat, wear, and breakage in demanding machining applications. Its uncoated design provides a sharp cutting edge that produces smooth finishes on materials such as steel, aluminum, stainless steel, brass, and plastics. With a diameter of 0.085 inches, a cutting length of cut (LOC) of 0.02 inch, and three flutes, this end mill is suitable for general-purpose machining, 3D carving, die & mold making, rapid prototyping, and wood engraving applications. Its square end shape eliminates the need for reorientation during operation, while its resistance to build-up extends tool life when working with abrasive materials or tough alloys at high speeds.
