Fast-Cut Carbide Rounded-Edge Square End Mills
 |
Rounded-Edge-Square Cut Style |
 |
4 Flutes |
 |
Ramping Cut Shown |
Variable spacing between the flutes reduces vibration, allowing these end mills to provide fast cuts, smooth finishes, and long tool life on hard materials. 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 nitride (TiAlN) or aluminum titanium nitride (AlTiN) coating allows them to 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. This makes these good for aggressive machining while roughing or making interrupted cuts.
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 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.
Center Cutting—Center-cutting end mills allow plunge cuts into a surface.

Variable spacing between the flutes reduces vibration, allowing these end mills to provide fast cuts, smooth finishes, and long tool life on hard materials. 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. They have a square end for milling square-bottomed 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.
End Mills for Extreme Ramping and Plunging—End mills for extreme ramping and plunging are good for both angled and vertical cutting. They can enter the material at up to a 45° ramping angle to reach the 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.

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. Aluminum titanium nitride (AlTiN) has a higher percentage of aluminum than titanium aluminum nitride (TiAlN).
Center Cutting—Center-cutting end mills allow plunge cuts into a surface.

Fast-Cut Carbide Square End Mills with Chamfer Corner
 |
4 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.
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.
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 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—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.

Variable spacing between the flutes reduces vibration, allowing these end mills to provide fast cuts, smooth finishes, and long tool life on hard materials. 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. They have a ball end for milling rounded slots, slopes, and contours. 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—A titanium aluminum nitride (TiAlN) or aluminum titanium nitride (AlTiN) coating allows them to 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. This makes these good for aggressive machining while roughing or making interrupted cuts.
4 Flutes—End mills with four flutes provide better chip clearance for high-volume, high-speed plunge, slotting, and roughing cuts.
