Carbide Square End Mills



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.
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. 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-nitride (TiN) coated end mills create less friction than uncoated end mills, which means they last longer when run at similar speeds. 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. 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.
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.
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).
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.
Center-cutting end mills allow plunge cuts into a surface. 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.

Fast-Cutting 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.
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.
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 end mills are extremely resistant to wear and diffusion because they have especially high hardness, even at high temperatures.
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 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 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.

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.
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.

Carbide Square End Mills for Honeycomb Panels

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.

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) 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.
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.

Fast-Cutting Carbide Ball End Mills


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.
