Query: General Tool H3487 Precision Drill Guide

I have used one of these precision drill guides two times to drill holes to put lock sets into doors. The cross slide that contains the drill chuck and shaft cracked through the chuck stop hole on the one side. The cross slide is too weak to even support the lightest duty service. The cross slide needs to be redesigned with flanges and beads at a minimum in order to handle normal loads encountered during use. Material changes to the cross slide my be needed. The design of the cross slide is a total failed effort.
