Fast-Cut Carbide Square End Mills with Chamfer Corner

A 45° corner chamfer improves cutting edge strength, so these end mills last longer than standard square end mills when milling hard material; however they do not create as sharp of a corner. Variable spacing between the flutes reduces vibration, allowing these end mills to provide fast cuts, smooth finishes, and long tool life on hard materials. They have a square end for milling square-bottomed slots, pockets, and edges. All are center cutting, allowing plunge cuts into a surface.

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.

End Mills with Coolant Holes—End mills with coolant holes allow coolant to run through the tool and directly to the cutting edge to help flush out chips. Use them in CNC machines with coolant-through technology.

Titanium Aluminum Silicon Nitride (TiAlSiN)-Coated Carbide—Titanium aluminum silicon nitride (TiAlSiN)-coated end mills are extremely resistant to wear and diffusion because they have especially high hardness, even at high temperatures.

Fast-Cut Carbide Rounded-Edge Square End Mills for Stainless Steel and Titanium


Rounded-Edge-Square Cut Style

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. Often used for slotting and pocketing cuts in mold and die making, these end mills have a 90° profile and rounded corners, which reduce flute breakage and chipping. Also known as corner radius 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. A titanium aluminum silicon nitride (TiAlSiN) coating makes them extremely resistant to wear and diffusion because they have especially high hardness, even at high temperatures. All are center cutting, allowing plunge cuts into a surface.

Carbide Rounded-Edge Square End Mills for Copy Milling

Rounded-Edge

Square Cut Style

Replicate the shape of complex parts with these end mills. Also known as torus end mills, they have a rounded edge for precision contouring. These end mills are also used for slotting and pocketing cuts in mold and die making. Their 90° profile and rounded corners reduce flute breakage and chipping. All are center cutting, allowing plunge cuts into a surface.

Fast-Cut Carbide Barrel End Mills

Barrel Cut Style

4 Flutes

6 Flutes

8 Flutes

Variable spacing between the flutes reduces vibration, allowing these end mills to provide fast cuts, smooth finishes, and long tool life on hard materials. Also known as barrel cutters, these end mills create the smooth finish of a ball end mill, but with a tapered cutting surface that removes more material with each pass. They're ideal for 5-axis machining where you need to cut from many angles. Plus, compared to ball end mills, they move farther between overlapping passes (stepover), which decreases machining time and tool wear, so they’ll last longer. All are center cutting, allowing plunge cuts into a surface.
