Serrations along the cutting edge act as chip breakers, so these cutters can remove large amounts of material at high speeds without sacrificing tool life. With larger diameters than end mills, they remove greater amounts of material to create a smooth, flat channel in the face of a plate, bar, or other wide workpiece. Compared to fly cutters, they’re more rigid, which makes for a better finish. Also known as shell cutters. With better heat and wear resistance than high-speed steel, these cobalt steel cutters can run at higher speeds and provide better performance on hard material, such as hardened steel, iron, and titanium.
Uncoated—Use uncoated cutters for general purpose milling and short production runs. They stay sharper than coated cutters when used on soft material, such as aluminum.
Titanium Nitride (TiN) Coated—Titanium-nitride (TiN) coated cutters create less friction than uncoated cutters, which means they last longer when run at similar speeds. Use coated cutters 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 cutters.
Aluminum Titanium Nitride (AlTiN) Coated—Aluminum-titanium-nitride (AlTiN) coated cutters dissipate heat better than other cutters, 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 cutters 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 cutters.
Coarse Pitch—Coarse pitch cutters create large chips for better performance on soft metals, such as aluminum, brass, and bronze.
Fine Pitch—Fine pitch cutters last longer than coarse-pitch end mills and produce smaller chips for better performance on hard metals, such as hardened steel, iron, and titanium.

Carbide Inserts for Replaceable Carbide-Insert Milling Cutters
 |
 |  |
Octagon | Round |
 | |
Square |
Combine a holder with carbide inserts to create a milling cutter, also known as indexable milling cutters. They remove metal at least two times faster than comparable high-speed steel milling cutters. When the cutting edges dull, replace the carbide inserts instead of the entire tool.
Use with an R8 shank arbor (sold separately).
Inserts sold individually come packed in a clear plastic case to protect cutting edges during shipment. Inserts sold in packs come factory sealed from the manufacturer for maximum traceability.
Titanium Aluminum Nitride (TiAlN)-Coated Carbide—Titanium-aluminum-nitride (TiAlN) coated inserts dissipate heat better than other inserts, especially at high speeds. At high temperatures, the coating creates a layer of aluminum oxide that transfers heat to the chips, keeping the inserts cool, even when used without lubrication.
Octagon—Use octagon inserts for general face milling. With eight cutting edges, they generate smooth cuts.
Round—Use round inserts for roughing and heavy cuts. Their shape makes them stronger than octagon and square inserts.
Square—Use square inserts to create a 90° corner when shoulder milling.
