Oversize-Tolerance Carbide Square End Mill

Manufacturer part: 28605A13

Also known as NC tolerance end mills, these carbide end mills have oversize mill diameter tolerances. They're sized to match standard high-speed steel end mills, so you can use them as longer-lasting replacements without changing the size of the cut. Made of solid carbide, these end mills are harder, stronger, and more wear resistant than high-speed steel and cobalt 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 a square end 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.
