Carbide Square End Mills


2 Flutes	3 Flutes	4 Flutes

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. 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. 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.

Uncoated Carbide—Use uncoated end mills for general purpose milling and short production runs. They stay sharper than coated end mills when used on soft materials like aluminum, leaving a better finish.

Titanium Nitride (TiN)-Coated Carbide—Titanium nitride (TiN)-coated end mills create less friction than uncoated end mills, which means they last longer when run at similar speeds. 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 Carbon Nitride (TiCN)-Coated Carbide—Titanium carbon nitride (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. 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 Aluminum Nitride (TiAlN)-Coated Carbide—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. 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.

Center Cutting—Center-cutting end mills allow 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.

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.

Fast-Cut Carbide Square End Mills with Chamfer Corner

4 Flutes

5 Flutes

6 Flutes

Ramping Cut Shown

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 for Extreme Ramping and Plunging—End mills for extreme ramping and plunging are good for both angled and vertical cutting. Choose these end mills so you can have one tool for ramping and plunging. They can enter the material at up to a 45° ramping angle to reach your desired depth faster than standard end mills, which typically machine at 1° to 3° angles. These end mills also evacuate chips faster and last longer.

Aluminum Titanium Nitride (AlTiN)-Coated Carbide and Titanium Aluminum Nitride (TiAlN)-Coated Carbide—Titanium aluminum nitride (TiAlN)- and aluminum titanium nitride (AlTiN)-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.

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.

Long-Reach Carbide Ball End Mills for Mold Making

Ball Cut Style

2 Flutes

These end mills have an extended neck with a reduced diameter that prevents them from rubbing against your workpiece when deep milling. Also known as runner cutters, they cut channels with precise angles and dimensions, reducing the need for additional finishing. They have a ball end for milling rounded slots, slopes, and contours. All are center cutting, allowing plunge cuts into a surface.

Aluminum Titanium Nitride (AlTiN)-Coated Carbide—Use aluminum titanium nitride (AlTiN)-coated end mills for demanding, high-speed jobs in hard material as well as for longer production runs. The coating reduces friction and vibration as they’re used, making them more wear resistant than uncoated end mills. They 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.

Fast-Cut Roughing Carbide Square End Mills with Chamfer Corner

Serrations along the cutting edge act as chip breakers, so these end mills can remove large amounts of material at high speeds without sacrificing tool life. Variable spacing between the flutes reduces vibration, also allowing these end mills to provide fast cuts. 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. With a high helix angle and wear-resistant titanium aluminum nitride (TiAlN) or aluminum titanium nitride (AlTiN) coating, these end mills provide excellent shearing and chip removal in stainless steel and titanium. They have a square end for milling square-bottomed slots, pockets, and edges. All are center cutting, allowing plunge cuts into a surface.
