End Mills and Milling Cutters

Carbide Square End Mills

Finishing Carbide Square End Mills

Intersecting flutes create a fine finish, making these end mills good for operations requiring light stock removal, such as deburring, profiling, and finishing.

Oversize-Tolerance Carbide Square End Mills

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.

Fast-Cutting Carbide Square End Mills

Variable spacing between the flutes reduces vibration, allowing these end mills to provide fast cuts, smooth finishes, and long tool life. They have a 90° corner for milling square corners in slots, pockets, and edges.

Fast-Cutting Carbide Square End
Mills for Stainless Steel and Titanium

Variable spacing between the flutes reduces vibration, allowing these end mills to provide fast cuts, smooth finishes, and long tool life. They have a high helix angle and a wear-resistant coating for excellent shearing and chip removal in stainless steel and titanium.

Fast-Cutting Carbide Square End Mills
for Tool Steel, Hardened Steel, and Iron

Variable spacing between the flutes reduces vibration for faster cuts, a smoother finish, and longer tool life.

Carbide Square End Mills for Carbon
Fiber, Fiberglass, and Graphite

These end mills have a diamond or diamondlike coating for machining abrasive material, such as carbon fiber, fiberglass, and graphite.

Fast-Cutting Carbide Square End
Mills for Aluminum, Brass, and Bronze

Variable spacing between the flutes reduces vibration, allowing these end mills to provide fast cuts, smooth finishes, and long tool life. They are uncoated for use in soft material, such as aluminum, brass, and bronze.

Carbide Square End Mills for
Aluminum, Brass, and Bronze

A titanium-carbonitride (TiCN) coating prevents soft material, such as aluminum, brass, and bronze, from accumulating on the cutting edge and creating an uneven finish.

Carbide Square End Mills for Nickel

Three high-helix-angle flutes provide a smooth finish on nickel alloys, such as Monel, Inconel, and Hastelloy.

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

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

High-Speed Steel Square End
Mills for Keyways in Rotary Shafts

Commonly used to make keyways in rotary shafts, these tools have a -0.0015" to 0.0000" mill diameter tolerance for creating a precise fit.

High-Speed Steel Square End Mills
for Aluminum, Brass, and Bronze

With a higher helix angle than standard high-speed steel end mills, these clear more chips and generate less heat, making them good for milling soft material, such as aluminum, brass and bronze.

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 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.

Cobalt Steel Square End Mills

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

Carbide Ball End Mills for Carbon
Fiber, Fiberglass, and Graphite

These end mills have a diamond or diamondlike coating for machining abrasive material, such as carbon fiber, fiberglass, and graphite.

Carbide Ball End Mills for Tool
Steel, Hardened Steel, and Iron

Flutes have a low helix angle to provide the cutting forces required for difficult-to-machine material, such as tool steel, hardened steel, and iron.

Carbide Ball End Mills for
Stainless Steel and Titanium

With a wear-resistant titanium-aluminum-nitride (TiAlN) coating, these end mills provide excellent shearing and chip removal in stainless steel and titanium.

Carbide Ball End Mills with Two Milling Ends

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

High-Speed Steel Ball End
Mills with Two Milling Ends

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.

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.

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.

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.

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.

Carbide Double-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. The teeth are angled on both sides so you can make top and bottom chamfer cuts without having to flip the workpiece.
