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.

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.

Aluminum Titanium Nitride (AlTiN)-Coated Carbide and Titanium Aluminum Nitride (TiAlN)-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. 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.

Noncenter Cutting—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.

Carbide Corner-Rounding End Mills with Two Milling Ends


Corner-Rounding Cut Style	3 Flutes

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 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 scooped corners for rounding the sharp edges of your workpiece.

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. The coating reduces friction and vibration as they’re used, making them 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. The coating reduces friction and vibration as they’re used, making them more wear resistant than uncoated end mills.

Aluminum Titanium Nitride (AlTiN)-Coated Carbide— 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. This makes these good for aggressive machining while roughing or making interrupted cuts. Use 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.

5 Flutes

6 Flutes

Ramping Cut Shown

End Mill with Coolant

Holes

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.

End Mills for 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.

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.

Fast-Cut Roughing Carbide Square End Mills

4 Flutes

Remove large amounts of material quickly without sacrificing tool life. Variable spacing between flutes reduces cutting time and vibration in high-volume jobs.

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 slots, pockets, and edges.

Titanium Aluminum Nitride (TiAlN)-Coated Carbide—End mills with a titanium aluminum nitride (TiAlN) coating and end mills with an aluminum titanium nitride (AlTiN) coating 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.

4 Flutes—End mills with four flutes have better chip clearance than end mills with five flutes, so they’re often used for high-volume, high-speed plunge, slotting, and roughing cuts. Serrations along the cutting edge act as chip breakers, so these end mills can remove large amounts of material at high speeds.

Center Cutting—Center-cutting end mills allow plunge cuts into a surface.

Carbide Square End Mills for Honeycomb Panels

8 Flutes

Cut into the sides and make slots in honeycomb panels without damaging any layers. Honeycomb panels are commonly used in aerospace and automotive applications because they’re strong yet lightweight, but these same qualities make them difficult to machine. Unlike normal end mills, these have a left-hand helix and push material downward as they cut, preventing layers of the composite material from separating. The serrated edges break the honeycomb into small pieces, minimizing uncut fibers that can occur in composite material. A diamond coating on these end mills allows them to machine abrasive material, such as carbon fiber, fiberglass, and graphite.

They have a square end for milling square-bottomed slots, pockets, and edges. All are center cutting, allowing plunge cuts into a surface. They are good for long production runs. They run twice as fast as other carbide end mills and last up to 30 times longer.

Carbide Square End Mills with Chamfer Corner for Stainless Steel and Titanium

Get longer life when milling hard material with these end mills—their 10° corner chamfer has a stronger cutting edge compared to standard square end mills. However, they don’t create as sharp of a corner. Grooves on the shank allow coolant to flow directly to the cutting edge, helping to reduce heat, extend tool life, and improve the evacuation of chips. This makes these end mills able to cut materials that are difficult to machine, such as stainless steel, titanium, and hardened steel. They have a square end for milling square-bottomed slots, pockets, and edges. Unlike typical noncenter-cutting end mills, these are designed for heavy plunge cuts.

A titanium aluminum nitride (TiAlN) coating allows them to dissipate heat better than other end mills, especially at high speeds.

Roughing High-Speed Steel Square End Mills

4 Flutes

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.

Center Cutting—Center-cutting end mills allow plunge cuts into a surface.

Cobalt Steel Tapered Square End Mills

Tapered Cut Style

3 Flutes

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 and steel. Also known as taper degree end mills, they're often used to machine angled slots in dies and molds.

Uncoated Cobalt Steel—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 Cobalt Steel—Use titanium nitride (TiN)-coated end mills for demanding, high-speed jobs in hard material as well as for longer production runs. They create less friction than uncoated end mills, which means they last longer when run at similar speeds.

3 Flutes—End mills with three flutes provide better chip clearance for high-volume, high-speed plunge, slotting, and roughing cuts.

Center Cutting—Center-cutting end mills allow plunge cuts into a surface.
