I'm working with metal that's about 2-3mm thick and I need to drill holes in very precise locations. I've noticed that regular drill bits tend to slide around when I start drilling, which makes it hard to maintain accuracy. Are there specific tools or stores that offer services for drilling in precise spots? Any suggestions would be greatly appreciated!

A drill press is probably your best bet for accurate drilling. You can find some decent options on FB Marketplace if you're looking for a budget-friendly choice. Just keep in mind that the quality can vary a lot, so check it out before buying!
For really precise work, consider using an automatic center punch. It makes a small dimple in the metal, which helps the drill bit stay in place instead of sliding around. You can snag one for around $2.44 at Harbor Freight!
I've heard good things about those. Have you had success with it on thicker metal too?
If you need super precise holes, using a punch to create a starting point can really help. After that, you can start with a smaller drill bit to avoid walking, then gradually work your way up to the size you need. Just apply even pressure and consider using cutting fluid for cleaner results!
Totally agree, that little dimple is a game-changer! It made my drilling so much easier.
