Create your own versatile milling cutters. These kits include a cutter body, inserts, wrenches, and screws. Also known as indexable end mills, replaceable insert milling cutters 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. The inserts come factory sealed from the manufacturer for maximum traceability.

Use with an R8 shank arbor (sold separately).

Kits come with either octagon or square inserts.

These general purpose saws are good for cutoff, slitting, and slotting applications in a wide range of materials, including aluminum, iron, and steel. Use with an arbor (sold separately).

Saws with a 2 _3/4" mill dia. are also known as screw slotting saws. Saws with 1 _1/4"-2 _1/2" and 3"-8" mill dia. are also known as plain metal slitting saws.

Coated inserts are best for demanding, high-speed jobs and hard materials. They’re harder and more wear resistant than uncoated carbide inserts.

Pair these carbide inserts with a holder to create end mills that reduce waste and cost in high-volume jobs. When all the cutting edges dull, replace the inserts instead of the entire tool.

Choose inserts with a smaller tip radius to reduce vibration and create smaller chips, so chip evacuation is easier. Choose inserts with a larger tip radius for more aggressive machining—they have a stronger cutting edge, so they remove more material with each pass.

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.

Use uncoated inserts for general purpose milling and short production runs.

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.
