Norton NTFB14 Stone India Aluminum Oxide Oil Stone 1/4" X 1" X 4 Fine Grit

Norton has always been the finest stone and is maintaining their quality.

Aside from diamond stones these are the only other stones I would really recommend.

Good for de-rusting old tools where keeping a flat surface matters. A bit aggressive for precision surfaces, but not unduly so.

I’ve used it to smooth things up and it works great

nice stone for cleaning up the mag chuck on my surface grinder. it also get used to clean up lathe tool tips.

I was expecting the stones to be very flat, but they had a slight bow. Seems like the kind of thing you wouldn't expect out of a stone.

I keep this stone in my machine shop. It doesn't take up much room in my tool box and is handy to have.

Works as it should
