Installation Notes

A licensed tradesperson or experienced technician should secure the workpiece firmly in a vise before threading to prevent movement. Apply cutting oil to the die and workpiece to reduce friction and extend die life. Thread the die onto the workpiece using steady, even pressure with a properly sized die stock handle, backing off periodically to clear chips. Follow applicable shop safety practices and wear appropriate eye protection when cutting threads.
