Excellent tool to cut .400” holes in T6600 Polynet tubing for FB23 and FB22 adaptors. Serrated cutting edge and large handle make the work easy. Long shank has room for an optional FB23 adaptor that makes the tool easier to hold. If you wish, you can also use the TL5 to push an FB23 into the tubing.
See the steps of the cutting process in the photo below.
