Sandvik CoroThread 266 toolholders achieve threading insert stability with a new design of iLock insert locking interface on the toolholder. This keeps the insert rigid, maintains the correct threading profile and reduces out-of-specification product rejection. The insert has a slot for each of its three indexable cutting edges. One slot is located on a raised guide rail on the new interface of the shim. This guide rail locks the insert in its correct position in the pocket, giving repeatable accuracy with each threading pass.

All of this means that the cutting loads on the insert are dispersed with no pressure points; insert and holder maintain their design integrity. Leading to longer tool and holder life, less downtime for tool changes and greater continuity of production!
