I Screwed Up BIG TIME on This One...

What happens here

The presenter uses aluminum oxide sandpaper to clean the top surface of the rusted bolt, ensuring a cleaner and more stable area for drilling. After cleaning, a spring-loaded center punch is used to create a small, precise indentation directly in the center of the broken bolt. This dimple will guide the drill bit and prevent it from wandering when starting the hole.

Goal: Before drilling, use aluminum oxide sandpaper to clean any remaining rust from the bolt's surface, then create a precise starting dimple in the center of the bolt with a spring-loaded punch.

Tools and materials

method that I'm trying. Okay, so the first thing I'm gonna do is I'm gonna take a little bit of this aluminum oxide sandpaper that I keep with my soldering kit. And I'm gonna go ahead. I'm just gonna try to just clean the top of that rust off there a little bit. So now I have a spring loaded punch right here and I'm just gonna try to get this right in the center and just give it a good pop. That way I can have a place to start my drill mark. So we've got that there pretty good then you just push down right there pretty much in the middle that little spring powered punch just made that mark. All right, so next we're gonna grab a cordless drill with a 316s bit.
