Cannelure Tool

This popular tool will roll a cannelure groove on any jacketed bullet from 17 to 45 caliber. Completely adjustable for depth and height. One setting will produce thousands of bullets. Also useful for making a second cannelure to lock the core to the jacket to control expansion of hunting bullets. Precision machined throughout. The cutting wheel is hardened to 59C Rockwell, so it will never wear out!
