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.
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.

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.
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.

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. 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-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.
Flute pitch indicates the size of the serrations on a roughing end mill. Coarse-pitch end mills create large chips for better performance on softer metal, such as aluminum, brass, bronze, and carbon steel.

Roughing Cobalt Steel Ball End Mills
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. 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 stainless steel, titanium, and tool steel. They have a coarse pitch and create large chips, so they’re also more efficient when working on soft metals such as aluminum, brass, and bronze. They have a ball end for milling rounded slots, slopes, and contours. 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.

Fast-Cutting Carbide Barrel 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. 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.
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.
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.
