Need Mechanical Advice

[H2OMAN]

I have two pieces of 1/4 inch hardened steel I need to drill one hole in each. I don't have a press. Just plain 'ol cordless drills. If I have the correct bit, can I drill through them or not? .30-06 M2 ammo cannot penetrate it so I'm thinking not but, thought I'd ask someone who might know.

With the right bit, some cutting oil, and a slow speed, then sure. There’s nothing magical about a drill press (or magnetic drill), except for steady pressure and a consistent slow speed.
You could just take it to a shop somewhere nearby and ask them to sell it for you, couldn’t you?

If you are using this for targets I would think you will find it needs to be thicker than 1/4 inch to stop a 30-06. What grade is it?

There’s always the old cutting torch too, if you don’t need a clean hole.

Clean holes are much better to work with

You could anneal (heat it to red hot then let it cool slowly) the area where you want the hole. Heat it to red hot then let it cool slowly. Then as mentioned above use a good quality bit, cutting oil and slow speed.

It's hardened level IV armor. It might be slightly thicker than 1/4 inch. But it can't be much.

Carbide bit, slow, with cutting oil.

Thanks buddy. Is there a name brand I should know about or just carbide in general?

Shoot it with some AP.

Might look to see if there's a shop that can laser it or water jet it for you.

Agreed, carbide will do the trick. I have used ones I just got from my buddy Bezos at Amazon. They worked for drilling my barrel to pin the flash hider.

Perfect. Thanks

Well, there it is fellas. I just want to thank you for your sage advise.

I forget the company I bought these from. But, if you decide to use these type of plates in your carrier you should really know what you are getting. This was not M 855. It was not even M193. It was Fiocchi Range .223. This is not good. Spend your money wisely and get some ceramic.
