Sandvik Coromant’s CoroMill QD cutters are designed to ease chip evacuation during groove milling and part-off operations. While chip issues can harm production efficiency, lower component quality or cause tool breakage—especially when machining narrow or deep grooves—these cutters’ optimized geometries and internal coolant make them ideal for such operations. The insert geometry deforms chips to a narrower shape than the groove from which they are cut, and then the coolant flushes them out.

A range of adapters complements the cutters, enabling their use on small, medium or large machining centers and multitasking machines. Adapters are also available for long-overhang machining. The internal coolant uses four-channel delivery to move from adapter to cutter.
