I'm putting together a spiral staircase and I'm having a tough time drilling through a vertical metal cylinder that will attach the railing to the stairs. Unfortunately, my partner had an accident earlier and drilled his hand while trying to hold the metal piece steady. The main problem is that the cylinder moves when we attempt to drill into it, causing our drill bit to bounce off the side instead of going straight through. Can anyone suggest safe methods or tools that could help us tackle this? If you need more details to provide suggestions, just let me know! Thanks!

I recommend starting with a center punch on the drill spot, then using a small bit to create a starter hole. After that, you can safely drill the full hole. An automatic spring-loaded center punch can be super helpful for making that initial dent. Just place the punch where you want it, and push straight down for that little dimple. No hammer needed!
Using a drill press is a solid option! You could also consider making a jig by cutting 45-degree notches in some blocks of wood, then clamping the cylinder in place to prevent it from sliding or rotating. Don't forget to use a center punch to dimple the metal at the exact drilling spot—it really helps with accuracy. Plus, ensure your drill bits are designed for metal and use the correct speed along with cutting fluid. And seriously, always wear eye protection when drilling!
Yeah, definitely a good call on the eye protection! You can't be too careful with power tools.
Check out the drill guides for pipes at Home Depot or Lowe’s. They’ll help keep everything steady while you drill; just make sure to use proper clamps to secure it. It makes the job much easier!
Totally! That method works like a charm. You could even do it a couple of times for a deeper dimple before drilling.
