Indexable Insert Milling Cutter

Indexable cutters are used wherever high repeat accuracy is required. This is not the case with a standard cutter because each time it is resharpened, some material is removed, making the cutters slightly smaller in their dimensions. When an indexable insert becomes dull, it is simply replaced with a new one. Indexable cutters are particularly worthwhile when the router is used frequently, as they save you setup time as well as the cost and trip to the sharpening service. It is especially important with cutters that have a guide ring, such as flush-trim cutters, that the cutting edges always align with the guide ring. This is only guaranteed over time with indexable cutters; with a standard flush-trim cutter, you already have a – albeit minimal – offset after the first sharpening. Another advantage of an indexable cutter: Hidden metal parts in the wood, such as nails, can render a standard cutter unusable. With an indexable cutter, on the other hand, you simply replace the cutting inserts.

Some indexable inserts have more than one cutting edge, so they only need to be rotated. Only when all the cutting edges are worn down do you replace them. Click on „Sketch” or „Image” for the replacement indexable inserts to view the cutting inserts.
