Replaceable Carbide-Insert Drill/Mill End Mills
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.

Replaceable Carbide-Insert Milling Cutters
Combine a cutter with carbide inserts (sold separately) 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). 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.
Use octagon inserts for general face milling. With eight cutting edges, they generate smooth cuts. Use round inserts for roughing and heavy cuts. Their shape makes them stronger than octagon and square inserts. Use square inserts to create a 90° corner when shoulder milling.
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.
