End Mills and Milling Cutters

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. They have one milling end and a standard shank.

Carbide Square End Mills with Two Milling Ends

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.

High-Speed Steel Square End Mills

These general purpose tools have one milling end and a standard shank.

High-Speed Steel Square End
Mills with Two Milling Ends

When one end wears out, switch to the opposite end for two times the life of a standard high-speed steel end mill. Made of high-speed steel, these end mills are for general purpose milling in most material, such as aluminum, brass, bronze, iron, and steel.

Cobalt Steel Square End Mills

These general purpose tools have one milling end and a standard shank.

Cobalt Steel Square End Mills with Two Milling Ends

When one end wears out, switch to the opposite end for two times the life of a standard cobalt steel end mill. 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.

Carbide Ball End Mills

These general purpose tools have one milling end and a standard shank.

Carbide Ball End Mills with Two Milling Ends

High-Speed Steel Ball End Mills

These general purpose tools have one milling end and a standard shank.

High-Speed Steel Ball End Mills with Two Milling Ends

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 Tapered Square End Mills

Use these end mills for general purpose work in most material, such as aluminum, brass, bronze, iron, and steel. Also known as taper degree end mills, they're often used to machine angled slots in dies and molds.

Carbide Tapered Square End Mills

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. Also known as taper degree end mills, they're often used to machine angled slots in dies and molds.

Carbide Tapered Ball End Mills

These tools have a tapered profile and rounded cutting edge for making smooth contours on intricate, three-dimensional shapes. They're also known as taper degree end mills. Made of solid carbide, they're harder, stronger, and more wear resistant than high-speed steel for the longest life and best finish on hard material.

Carbide Rounded-Edge 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 Rounded-Edge Square End Mills

Made of cobalt steel, these end mills have good heat and wear resistance, so they can run at high speeds in hard material. Often used for slotting and pocketing cuts in mold and die making, they have a 90° profile and rounded corners, which reduce flute breakage and chipping.

Carbide Corner-Rounding End
Mills with Two Milling Ends

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 and cobalt steel for the longest life and best finish on hard material. Use them to round sharp corners on the edge of your workpiece.

Carbide Corner-Rounding 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. Use them to round sharp corners on the edge of your workpiece.

Carbide Chamfer 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 angled profile allows chamfer, bevel, and other angled cuts.

Carbide Drill/Mill End Mills

Made of solid carbide, these end mills are harder, stronger, and more wear resistant than cobalt steel for the longest life and best finish on hard material. A 90° pointed tip allows them to be used for drilling as well as for slotting, profiling, chamfering, and spotting cuts.

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.

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.
