This tool is designed to cut the outside diameter of a barrel within close proximity to the size needed for 1/2” threads (1/2x20, 1/2x28, 1/2x36, etc). The barrel diameter must be no larger than 1” for this to tool to function properly.

This kit contains:

(1) 1/2” HSS Annular Cutter

(1) .22/.223 cal cutter pilot

(1) Annular cutter holder to drill adapter

The cutter should be ran VERY slowly (200RPM Max) and lubricated constantly. Do not attempt to use the cutter without the pilot as the cut diameter will not be concentric to the barrel.

Please note that NTC Trading Co expressly denies any liability for the proper or improper use of this tool and highly recommends a machinist level skillset prior to attempting to use it. (Use at your own risk).
