Machine Expansion Taper Shank Reamers
Straight Shank Expansion Chucking Reamers are taper fluted, end cutting tools used to enlarge previously formed through holes to a precise diameter with a smoother finish. The tapered shank on these reamers are used in a Morse taper socket toolholder in a variety of standard portable or stationary machines. The adjusting screw can be tightened to permit expansion back to the initial size after wear in the cutting end, increasing tool life and saving money. It can then be reground to the appropriate size and resharpened.
