Was used to cut a seized bearing outer race by making one cut through and collapsing the old bearing. Cut nicely. Hopefully is still good for another use.

Stays sharp and cuts through practically anything. I use it mainly on 1/4″ thick (or thinner) mild steel and various other metals, and it works great. I’ve used it both in my rotary tool and in my drill press. Either works, but you still have to be careful not to twist too much or else it will break (it is carbide, after all).

Perfect

I had to enlarge a hole on my snowplow. This cutter looks like a joke but I put it in my Dremel and it worked great. I am surprised at how well it cut and is still cutting.

Used this to modify a chainsaw bar to adapt to a vintage saw. Worked well.

I am a locksmith and use these tools to “adjust” lock strikes where doors have settled or were not installed properly. These tools last for years and will cut almost anything, including stainless steel. If you have a tough material to cut or anything less, this tool will do the job.

This cutter works great. I weld and then use these to reshape. They seem to last forever. I go through a few only because I loose them. Great tool.

The product did better than I expected in grinding out a hug that had debre left in it from a bearing race that had melded to the hub. Had never used a drimel tool, borrowed my brothers, bought the grinding tool and it was fantastic. As a new user I wish the package had more explanation as to what tools are used for and on what materials to be used.

The bit was very useful while I did not need to rent a tile cutter. It held up and glided through the ceramic tiles and grout. It is an excellent tool to have in your toolbox.
