Carbide Square End Mills
For longer tool life and a better finish in general purpose milling applications, these solid carbide end mills are harder, stronger, and more wear resistant than high-speed steel and cobalt steel end mills. 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.
End mills with fewer flutes provide better chip clearance for high-volume, high-speed plunge, slotting, and roughing cuts; end mills with more flutes provide a finer finish and operate with less vibration when run at high speeds.
Use uncoated end mills for general purpose milling and short production runs.
Center-cutting end mills allow plunge cuts into a surface.

High-Precision Cubic Boron Nitride Ball End Mills for Tool Steel and Hardened Steel
Make finishing cuts in tool steel and hardened steel with these cubic boron nitride (CBN) end mills. Harder than carbide end mills, they’re better for making small, precise cuts and last more than five times as long. And while they’re not as hard as diamond end mills, they dissipate heat much better. These end mills have a 0° helix angle for increased rigidity, helping to prevent chipping and ensuring more precise cuts. Deep chip pockets remove small chips for greater precision and to prevent surface roughening.
Because they’re brittle, these end mills require a highly rigid setup such as a CNC machine to prevent them from breaking. It’s also recommended that they’re used with oil coolant.
