Die Grinder attachments for mild steel?
 

I need to clean up the inside of my turbo flange where I welded like a 5 year old. I can't seem to find a good attachment that will go through the mild steel well at all. Any suggestions?

Carbide cutter or sanding flappers.

Really? Any standard die grinder bit I've used goes thru mild like butter. Maybe your grinder is spinning backwards.

Why would you let your 5 year old self weld?

I would of let someone more mature do it :giggle:

Carbide Rotary files(burrs),Grinder needs to spin in the direction of the cut of the burr.Any thing less will just "polish" the weld,not really cut it.

a weld is not like mild steel unless you have gas welded it however like previously mentioned a carbide tip or flap wheel will do
