The TRU-CHOKE Thinwall-Style Tooling by Manson Precision allows for the installation of choke tubes using a lathe for superior results, although hand installation is possible.
It features precision ground high speed steel tap and reamer with interchangeable pilot bushings for accurate bore alignment, and an enhanced end relief on the reamer for a faster cut.
Designed specifically for 12 gauge shotguns, the tooling is compatible with thinwall-style tubes only and is approximately .020" thinner than standard Tru-Choke tubes.
