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.
