I cut a lot of threaded rod in my small shop. Using hand tools or portable cutters has never worked as well as I would like. Rather than spending a lot of money for a good cut off saw I designed a small jig that holds a drill and cheap cutting disks from Harbor Freight.
I also wanted to be able to cut a slot in the end of the threaded rod to make it easier to screw into various projects.
The system works very well. It cuts fast and is very straight. No clean up is required to put a nut on. The video shows the whole process.
Thanks for taking a look!
