Carbide Ball End Mills for Tool Steel, Hardened Steel, and Iron

Ball Cut Style

Flutes have a low helix angle to provide the cutting forces required for difficult-to-machine material, such as hardened steel and iron. 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.

An aluminum-titanium-nitride (AlTiN) or aluminum-chromium-nitride (AlCrN) 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.

With a mill diameter of 3 mm or less, these end mills are great for precise, detailed work such as in electronics, mold making, and medical-device manufacturing. 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. All are center cutting, allowing plunge cuts into a surface.

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

End mills with four flutes provide a finer finish and operate with less vibration when run at high speeds. They have variable spacing between the flutes which 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. 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.

An aluminum-chromium-nitride (AlCrN) coating provides excellent resistance to wear, high temperatures, and oxidation—even at high speeds. Great for difficult-to-machine materials like stainless steel, titanium, and tool steel.

Replaceable Carbide-Insert Drill/Mill End Mills

Drill/Mill Cut Style

Fasten one insert to the center of these end mills and three more to the sides, and you can use them for drilling, shoulder milling, contouring, and finishing. When the cutting edges dull, switch out the inserts instead of replacing the whole tool. These end mills help you reduce waste and costs in high-volume jobs. The inserts are locked in place with a screw for a hold that’s strong enough to handle the high speeds of a CNC machine.

Inserts have a positive rake, which means the cutting edge is angled to reduce vibration and prevent thin workpieces from bending. For a longer life, each insert has two cutting edges—rotate the insert when the first side wears down. They have chip breakers to stop long chips from forming, so they won’t block the flow of coolant or damage your tool. Inserts sold individually come in a clear plastic case to prevent damage during shipping. Inserts sold in packs come factory sealed from the manufacturer, which makes them easy to trace.
