I had bought a bunch of taper shank drill bits a while ago. They were a little rusty so I soaked them in some rust remover. What a difference. Here is one 2-1/4” bit after 20 minutes

Cheers

I've been using Evaporust on some tools I bought recently and I have been amazed at the results. That stuff really works!

I soak my cleaned and derusted parts in used synthetic engine oil. No rust on anything after treated and I live in heat and humidity central.

Wow Martin, you must have a really big DP to run those drills!

Can we get a picture of the beast that can run those bits??? :drool:

What can I say, I like heavy equipment and it’s usually cheap.
The 2-1/4" and 2-3/4" bits have 5MT shanks. The only machine at the moment I can use them is my Lathe, which most times a boring bar is better. Most of the rest have MT#3 shanks which I can use in the Progress #3 drill press.
I am looking at a Radial arm drill that has a #6 MT but I am still trying to figure out how to get it home reasonably priced. It weighs more than the roll off truck can handle.
Cheers

What brand rust remover are you using? I have tried several over the years and have not found one yet that does that good of a job. Every one I've used leaves a black coating where the rust has been removed.

That is now preserved Iron(III) oxide. Same as bluing but much thicker in your case. It won't rust again

Project Nut, I’m using Evaporust. This is right out of the solution with no scrubbing. I just rinse with water and dip in again and let it air dry.
