Sure beats messing around with a file or even a grinder. Just watch your drill speed. Wished I had this years and a lot of redi-rods ago.

Have seen all the videos and reviews, so hoped it would work, and it did. Used for multiple bolts on a hot rod fabrication. Used on 3/8 stainless threaded rod to hold in a gas tank. Deburred the ends without a problem and the bolts threaded on without a problem afterwards. Used on grade 8, 5/8 inch U bolts after they were cut down for a rear end. Worked effortlessly on those also. Used on a few other bolts during assembly also, and did not have a problem with the tool working as it should. Just to note, you will need a vise to hold the item while working on it, don't expect to just hold the item by hand and it to work. You need to apply a bit of pressure to it as it cuts. But it will do the job and do it well. Will definitely not be without one in the future, and will probably order an extra just in case one gets misplaced.

Did a great job

I saw another electrician use one ( i am one as well) and I hated having to fight getting nuts on all thread after I cut them or file the ends by hand. I've had this for a couple weeks now and I've used it every day. 3/8 and 1/4 all thread. It works. I have found using it on an impact seems to work better than a regular drill. I think the faster/higher rpm makes for a smoother and more consistent cut. When it's a rougher cut you will get chatter and as soon as it does its cutting it smooths out. Overall I think its a tool worth buying and if it broke tomorrow I would buy one immediately again.

Thanks to a neighbour who described a "tapering" bit which might work, I searched and found these chamfering tools, and used this particular one to clean up the threads on a motorcycle with a damaged rear sprocket stud. It worked great to clean up the first couple of damaged threads so we could get a new nut on to install a new sprocket. It saved time and money trying to source a replacement stud or a new hub ($$$$). Not bad for $16 on sale.
