Taper any wood shaft up to 3/8". The tool incorporates a fully
adjustable depth of taper stop for both nock and point.
The heavy tool-steel cutting
blades produce clean tapers with tolerances within .003".
Includes sizes 5/16", 11/32" and 23/64".
I have been tappering my arrows for a couple of years with a jig and sander. As long as the blades a sharp and adjusted correctly this tool cuts my time in half, with the same results. Great tool.
