Cutting inserts

Milling inserts are removable cutting tips, which means they are not part of the milling machine. They are indexable which means that they can be exchanged and replaced once used. Milling inserts are used with milling cutting tools when cutting or shaping metals such as steel, alloy and cast iron. They're designed to protect your milling cutter from damage caused by extreme heat and force, ensuring longer tool life. This, in turn, can help you work more productively because your tool won't buckle or change shape.

There are many parameters to consider when choosing the most suitable turning inserts. Carefully select insert geometry, insert grade, insert shape (nose angle), insert size, nose radius and entering (lead) angle, to achieve good chip control and machining performance.

To fit or change your milling inserts, you need a hey key (also known as Allen key) or a screwdriver. There are clamps on the milling cutter that are screwed in. You need to undo the screws on the clamps and then insert the milling inserts. Finally, re-tighten the screws so that the milling insert is secure.
