How to drill in the centre of any bolt

I don’t get it, what’s the bearing doing. The hole isn’t even in the middle

It is criminal to use a file as a hammer.

Roller Bearing was of no help in this video...🤦‍♂

Yeah you can forget all the bearing nonsense and just chuck up the workpiece bolt with a nut on the end so you can clamp onto it with the vice and line it up perfectly below your drill press. Then clamp your vice in place, remove the nut from the bolt and lock a drill bit in the vice. The spinning workpiece ensures the hole is dead center and everything is lined up straight on so you don't drill at a weird angle. Also, peck drilling will help a lot in these cases. Finally, water is a terrible lubricant for metal drilling. Just use some 3 in 1 oil if you have nothing else. It's cheap as dirt. Hell, even olive oil would be better than water.

I don't understand the bearing

There is a thing called a lathe, which is known since 1750. If you don't own one, find a person who does..

As a youngster i had loads of those hammers. They were kept in the 'Filing cabinet'

I hope your day job is calling me about my vehicles extended warranty because machining isn't your best skill.

how does this do anything?

Nobody even noticed the super safe way that he used the grinder?

Files are very brittle, so they easily break on impact. They are the last tool in my tool box I'd use to strike something like a hammer.

I cannot see what the bearing was for?

I like your little vise. Where can I get one?

Oh I get it .. that's a splash feed water switch for his broken electric fidget spinner.

That is very useful. Thanks!

6:16……holy spitballs!

You don't tell what drill bit that you use.

When you have a drill press simply fix the bolt on vase and push the drill down on need to this game

NUTS!

So nice
