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.

Cut down on waste and cost during high-volume jobs. These end mills consist of a holder and a carbide insert, so you can swap in a fresh cutting edge without replacing the whole tool. 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. They’re held at an angle, so you can create chamfers, bevels, and other angled cuts. You can also use them like a face mill for flat surface cutting.

Inserts have a positive rake angle, 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.
