Milwaukee’s new Door Lock Installation Kit (49-22-4073) is designed to make it simple to align and drill holes in slab doors. It works with wood and metal interior and exterior doors from 1-3/8″ to 1-3/4″ thick and uses an auto-centering drill guide to accurately center the latch hole, a non-slip clamp design to prevent accidental movement of the guide and an anti-splinter depth stop for a clean finish. The Door Lock Installation Kit is priced at about $35.
