Deburring External Chamfer Tool Stainless Steel Remove Burr Tools for Drill Bit Stainless Steel Eliminate Damaged Extractor Fits Size 8-32 Bolts (Silver)

A nice addition to the collection, it will save a lot of time and effort.

Well if this is the standard of Amazon marketplace I don't think I will be purchasing in the future. This is the second item I have bought with glowing reviews then a few days later they all disappear and replaced with bad ones!First off it is blunt and has no cutting face it's supposed to go down to M4 but M8 was the smallest bolt I could try, absolutely useless even tried on M12 all mild steel 8.8 didn't even touch it.I believe the material isn't even hardened so will not cut any surface, I'm sending this back so dissapointed. The one I recieved doesn't even look like the photos, all I can say glad I tried it before I put it in the tool box not to be used in a while to discover it's garbage.

Works well as long as it is used on a slow speed , to fast is now good 👍

Looks good i haven't used it yet

Somewhat disappointed with this, it doesn't work as well as suggested and I needed to tidy up the threads of the bolts I used it on..

Excellent. Deburrer the end of a 10mm piece of threaded rod easily no more faffing around with a file a quick blast with this and the nuts goes on first time. Saves time when installing containment

I bought this to clean up some threaded bar I was using for a 3D printer spool feeder project and it wasn’t sharp enough to clean up the end of some m6 threaded rod. Very disappointing.

Does what it says on the box great for cleaning up the thread after sawing off if you don't have a nut, works every time
