Installation Notes

Installation should be performed by a qualified machinist with the machine powered down and the spindle fully stopped. Ensure the shank bore and taper surfaces are clean and free of chips or debris before mounting. Thread engagement at the 7/8-20 interface should be checked for full contact before torquing the boring head body into place. Follow the machine tool manufacturer guidelines and applicable shop safety procedures when setting tool reach and boring head offset.
