Sandvik’s CoroThread 266 family of rigid, high-precision threading tools are available in 0.5" and 0.625" insert sizes. The tools are buil to high levels of stability through the iLock insert locking system. With this design, an insert contains a slot for each of its three indexable cutting edges. When locked into place, these slots correspond to a raised guide rail on the actual tool, providing a much more stable interface. According to the company, the iLock system simplifies tool setups, eliminates potential insert movement during machining and provides repeatability with high levels of accuracy. Additionally, iLock disperses cutting forces with no pressure points to reduce the strain on both tool and insert.
The E-tolerance of the system is 0.0004" axially and 0.002" radially, minimizing the effects of changing cutting edges to ensure maximum product consistency, the company says.
