By far the best boring machine ever made. The only machine I will use. Millers Falls machines employ a solid 4 legged steel frame as opposed to a sloppy 2 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 little to no wear. Accepts any standard 1/2 inch shank boring machine bit, which we have listed separately. This machine has been cleaned, oiled, inspected, paint touched up and a new base installed. It has a depth stop for perfectly even mortise bottoms. Just flip the switch and slide the withdrawal gear over and the bit is withdrawn. Adjustable cranks to regulate speed and power.
