Carbide Inserts

Carbide inserts are indexable pieces of cemented carbide used for machining, face milling, cutting and finishing. They can be used to finish a range of materials, including stainless steel and cast iron. When searching for the correct carbide insert, you’ll need to know its Turning Tool ISO reference. The ISO number provides crucial information on the clamping method, insert shape, holder style and much more. You can learn more about how to identify carbide inserts by reading our in-depth article covering the subject, including the insert grade, insert style, tool holder and more.

Carbide milling inserts

Carbide milling inserts are used to provide precision cutting in milling machines. We stock a vast range of carbide milling inserts in different grades and sizes. We have products in stock and ready to ship from leading manufacturers such as Edgetech, Europa and Pramet.

Carbide turning inserts

Carbide turning inserts are used to remove material from a workpiece with a leading edge. We sell a selection of carbide turning inserts suitable for precision work, including aerospace applications. You’ll find cutting tools from brands such as Edgetech, Edge Tec, Europa and ISCAR.

Carbide Inserts FAQs

To identify the carbide insert you need, you’ll need to use the Turning Tool ISO code system. This system provides details on all aspects of the insert, it’s holder and their lengths. If you’ve already got a carbide insert to hand, you can use the Tuning Tool ISO number to order a replacement. If not, then check out our guide on how to identify carbide inserts or give us a call.
