Carbide Inserts for Replaceable Carbide-Insert End Mills


Pair these carbide inserts with our Replaceable Carbide-Insert End Mills. They have a mounting hole that allows you to fasten them directly to the end mill for a hold that's strong enough to handle the high speeds of a CNC machine. All have a positive rake, which means the cutting edge is angled to reduce vibration and prevent thin pieces from bending. All have chip breakers that prevent the creation of long chips, which can damage tooling and restrict the flow of coolant.
Use uncoated inserts for general purpose milling and short production runs. Use aluminum-titanium-chromium-nitride (AlTiCrN) coated inserts for demanding, high-speed jobs in hard material. They’re harder and more wear resistant than uncoated carbide inserts.

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 Counterbores
Designed to reduce waste and costs during high-volume jobs, these counterbores consist of both an insert and a holder. When the cutting edges dull, you can replace the insert rather than the entire 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. These counterbores create flat-bottomed holes that allow socket head screws to sit flush with the surface of your material.
Inserts have a positive rake, which means the cutting edge is angled to reduce vibration and prevent thin workpieces from bending. For longer life, each insert has three cutting edges—when one edge dulls, rotate to the next one. 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 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.
