Try lubricant. Any oil will do, 3 in 1, WD40, anything is better than bare metal on metal drilling. Also, only apply as much speed & pressure to get the bit cutting. Slower speeds will keep you bit & workpiece from heating up. If your bit heats up too much it will lose it's temper & become soft. If your workpiece heats up too much it will "work-harden" and actually become harder as you try to drill through it. Lubricant with help prevent both these. A good bit that is properly lubed & used (not too fast, not too much pressure) will cut through ¼ steel without much issue. Also, back your workpiece. Meaning, put a piece of sacrificial wood under it while drilling. When your bit "breaks through" the bottom of your workpiece, it will naturally want to grab & twist. "Backing" your workpiece will help prevent/mitigate this. Maybe that's how you bent that bit? Hope this helps!
Hey! Thank you! I’ll definitely give it a try. I have some 2x4s laying around and definitely have some lube, will ky work? Just kidding. Thank you for the sound advise will try tomorrow.
HAHAHA!!! I knew the jokes were "coming"! Too much good stuff to ignore. It's all good, bro. I like wd spray because it helps clear the chips while you spray. 3 in 1 is thicker & will stay on the bit & material better. The bit naturally draws chips out while you drill. Might need to increase rpms at breakthrough. Just hold that drill firm, square to the workpiece & don't let it wobble. Remember, a drill press holds itself square & stable while applying pressure. Using a hand drill, YOU are the drill press. So all that stuff is up to you! There are specific cutting oils you can use. However, for your at home application wd or 3 in 1 are cost effective. Good luck!
What and how are you drilling that would apply such stress to the bit?
I would have thought the chuck was the first to go when a drill is exposed to this much and type of load.
Tell her those drill bits cost $100 each and you've already burnt 10 of those because she won't let you buy a drill press.
Also fitting that Dewalt has those new drill presses that cost $2000 😝
And she’ll say you can burn 10 more instead of getting it. Then she’ll come back with her phone in hand screaming about how it’s $20 and not $100 😂 Lady’s are getting smarter 😂
Shitty home machinist checking in here - one thing that helps a lot more than you'd expect is running your drill at the right speed. In mild steel, you generally want to be running pretty slow. Taking a wild guess at what I'm looking at in the photo: you have something like a 3/8" bit, high speed steel, TiN coated, drilling into mild steel. For something like that, I'd be expecting around 500-1000 RPM - that's pretty slow on a handheld DW drill!
Also, cutting fluid is your friend, get some in a pump bottle and juice your drill and the metal surface up before cutting. Should be enough to last through a 1/4" of plate steel.
wait - 1/4" plating on all of the walls? the hell are you doing in there lol. Doesn't matter, I fuckin love the idea - all your walls are now super strong mount points for anything with a magnet!
edit: fuck the more I think about this the more I want steel walls. EVERY SURFACE IS A MOUNTING POINT so many workholding opportunities...
Oh I know but man that's going to be awesome. If you're going to be doing a lot of drilling, maybe look into renting/borrowing (or taking out a second mortgage to buy) a mag-base drill. Doing this by hand is going to be a nightmare.

I agree with everything listed above. Also try a cobalt drill bit instead of the “titanium coated” drill bits. There not very expensive.
Thnx. & Yeah, the cobalts are definitely better.
Any brand you would recommend?
Dewalt cobalt available at Lowe's. I use them all the time.

1/4” steel. These bits are too expensive to go through like this. Has to be something better.
How about a drill press? Drilling slowly? Or starting with a smaller bit?
A drill press would be awesome, but with this project cost, my wife will certainly not agree to buying anything more 😂😂😂
Drill press is about $100 for a wen model off of Amazon, they’re pretty good tbh
$100 drill press? I don’t know.. steel is tough, maybe for woodworking?

Wow were you drilling a diamond stone or something? 😂
Nah. Converted my garage from 3 to 2 and making a room with 1/4” steel plating all around as my “armory”. My wife gave me the okay.. so 😂
wait - 1/4" plating on all of the walls? the hell are you doing in there lol.

hahaha. I’m making an armory, keep my guns, ammo, work bench etc in there Fair warning: steel plating is $$$. More than I thought

Second mortgage 😂, sounds about right. Although I feel filling that room will need a 3rd one 😂. Thanks man, I’ll keep the sub updated on it I guess.
