Used to say filing by hand was the only real way, but a messed up order from a new steel batch got me to try a grinder. Now I'm all for it.

Build on what @jordan_mitchell95 said by seeing how the right disc keeps the steel's structure safe. You end up with parts that don't fail later from hidden heat damage. That's the real win over old hand methods, saving hassle down the line.

Something a lot of people don't talk about is how the grinding disc can change the steel's tiny surface cracks. If you use a disc that's too aggressive, it doesn't just overheat the metal, it pushes stress into the material. Those hidden stresses turn into small cracks that grow with use. Picking the right disc spreads the force out and keeps the surface calm. That means the part holds up under load way better, not just looks good. It's why skipping the proper tool can bite you months later when something breaks.

Honestly, same thing happened to me last year. Once you get the right grinding disc for the steel you're working with, it's a total game changer. Takes a fraction of the time and the finish is just cleaner. Just go slow at first so you don't take off too much material. It feels like cheating after doing it by hand for so long.

I saw a video from a welding shop in Texas that broke down disc types for different steels. What @jordan_mitchell95 said about going slow is spot on, especially for beginners. They showed how a coarse disc on mild steel cuts fast but leaves deep marks, while a finer one on alloy steel prevents overheating. It totally changed how I approach grinding now, because I used to just grab whatever disc was handy and wonder why my results were inconsistent. Getting the right disc isn't just about speed, it's about not wrecking the material, which saves money and time in the long run. So yeah, investing a bit in the proper tools makes all the difference, lol.
