By far the best boring machine ever made. The only machine i will ever use! MILLERS FALLS machines employ a solid four-legged steel frame as opposed to a sloppy two-legged wood frame. This one is as tight as the day it was made, 100% complete, and ready to use. The bearings and teeth show no wear. Accepts any standard 1/2" shank boring machine bit, which we have listed separately. This machine has been thoughtfully cleaned and oiled. A copy of the original label has been applied to the deck. It has a depth stop for perfectly even mortise bottoms. Just flip the switch and the bit is automatically withdrawn. This is one of the finest examples we have ever sold.
