By far the best boring machine ever made. The only machine I will ever use. Millers Falls boring machines employ a solid 4 legged steel frame as opposed to a sloppy, fragile wooden 2 legged 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 inch boring machine bits, which we have listed seperately. This machine has been refinished, inspected & oiled. It retains its original depth stop for perfectly even mortise bottoms. Bit withdrawal is automatic. Just apply slight pressure to your left and keep cranking.
