The tools you're bidding on are approx. 11" long and used to form the hole needed to handle hand made hammers, axe, or tomahawks etc. The process used buy most smiths is to drill a series of small holes as close together in the center of the workpiece to be drifted. Once the holes are drilled heat the item and use a cold chisel or similar tool to split the piece. Once split, heat the piece again and drive the drift through the hole. Tap the sides of the workpiece while continuing to drive the drift into the workpiece until the drift hole gets to the desired measurement. The process of heating may be needed several times to get the desired shape. The large hammer drift tool measures 5/8 x 3/4 at the small end and tapers oval up to 7/8 x 1 1/4 at the large end. The mouse ax drift tool measures 5/8 x 3/8 at the small end and tapers up to 5/8 x3 /4 at the large end. The tools are made of tough 60/45 ductile iron.  These castings have been produced for many years and  have proven to be very reliable and useful. I will be listing several different products used in the trade of blacksmithing so please look at my other auctions. All tools are new and in very good condition. Casting weighs approx. 4 lbs. ea. Buyer pays actual shipping cost. Made in the USA!
