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. Made of solid carbide, they are harder, stronger, and more wear resistant than high-speed steel and cobalt steel end mills 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. End mills have a square end for milling square slots, pockets, and edges. All are center cutting, allowing plunge cuts into a surface.
Titanium-aluminum-nitride (TiAlN) coated end mills dissipate heat better than other end mills, especially at high speeds. At high temperatures, the coating creates a layer of aluminum oxide that transfers heat to the chips, keeping the tool cool, even when used without lubrication.

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. 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.
Noncenter-cutting end mills are for operations where the peripheral teeth do most of the work, such as shoulder milling, contouring, and finishing. They cannot be used for plunge cuts.

Roughing High-Speed Steel Square End Mills
Serrations along the cutting edge act as chip breakers, so these end mills can remove large amounts of material at high speeds. They are high-speed steel for general purpose milling in most material, such as aluminum, brass, bronze, iron, and steel. Their square end makes them good for milling square slots and edges.

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. They have a square end for milling square slots, pockets, and edges.

Use uncoated end mills for general purpose milling and short production runs. Use coated end mills for demanding, high-speed jobs in hard material as well as for longer production runs. They’re more wear resistant than uncoated end mills. Titanium-carbonitride (TiCN) coated end mills have a hard, smooth finish that resists chipping and wear and prevents material from accumulating on the cutting edge. They’re especially good for use in aluminum.
Flute pitch indicates the size of the serrations on a roughing end mill. Coarse-pitch end mills create large chips for better performance on softer metal, such as aluminum, brass, bronze, and carbon steel.
