Carbide Square End Mill with Two Milling Ends

Manufacturer part: 8888A33

When one end wears out, switch to the opposite end for two times the life of a standard carbide end mill. Made of solid carbide, these end mills are harder, stronger, and more wear resistant than high-speed steel for the longest life and best finish on hard material. Their extreme hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the end mill from breaking. They have square ends for milling square slots, pockets, and edges. All are center cutting, allowing plunge cuts into a surface.End mills with two flutes provide better chip clearance for high-volume, high-speed plunge, slotting, and roughing cuts.Use uncoated end mills for general purpose milling and short production runs.
