End Mills and Milling Cutters

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.

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.

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.

Carbide Ball End Mills

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.

Cobalt Steel Ball End Mills with Two Milling Ends

With better heat and wear resistance than high-speed steel, these cobalt steel end mills can run at higher speeds and provide better performance on hard material, such as iron, hardened steel, titanium, and tool steel. When one end wears out, turn the tool around for a sharp edge.

High-Speed Steel Ball End Mills

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

Engraving End Mills

A fine-point tip cuts lettering, designs, and logos in a variety of metals and composites, such as aluminum, fiberglass, and titanium.

Drill/Mill End Mills

These multifunction tools have a 90° pointed tip that allows them to be used for drilling as well as for slotting, profiling, and chamfering cuts.

Tapered End Mills

Also known as taper degree end mills, these end mills are angled from anywhere between 1/2° and 45° for machining angled slots in dies and molds.

Chamfer End Mills

More angled than tapered end mills, chamfer end mills have cutting angles of 45° and higher for making chamfer, bevel, and other angled cuts.

Carbide Corner-Rounding End Mills

Rounded-Edge Square End Mills

Often used for slotting and pocketing cuts in mold and die making, these end mills have a 90° profile with rounded corners, which reduce flute breakage and chipping.

Undercutting End Mills

A fine-point tip cuts lettering and numbering and makes designs in a variety of metals and composites, such as aluminum, fiberglass, and titanium.
