The Morse #1 blank is made from 1.25″ diameter free machining steel and is available so that you can make your own custom tool holders. The billet end comes in either 0.830″, 2″ or 4″ lengths. The proper #1 Morse taper is already machined onto the tapered end, and it is drilled and tapped for the included drawbolt. You need only turn, drill, tap, or slot the blank to fit your special tooling needs. Included with the blank is an instruction sheet showing some common uses with dimensions for making a fly cutter, a slitting saw holder, and an end mill holder.
