Milling

Cobalt Steel Square End Mills

With better heat and wear resistance than high-speed steel, cobalt steel end mills can run at higher speeds and provide better performance on hard material.

Carbide Square End Mills

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.

High-Speed Steel Square End Mills

Use these end mills for general purpose milling in most material, such as aluminum, brass, bronze, iron, and steel.

Ball End Mills

Good for rounded slots, sloping cuts, and contours, ball end mills have a rounded cutting edge.

Fly Cutters

These end mills clamp onto tool blanks to machine flat surfaces. As the cutter rotates, the tool blank creates a wide, shallow cut on the face of the workpiece.

Face Milling Cutters

A large mill diameter allows you to remove a large amount of material per pass.

End Mill and Milling Cutter Sets

Keep multiple sizes of end mills on hand so you have the right size when you need it.
