Best drill bit for hardened steel, how to drill through a broken bolt amazing results

In this short video I’m stuck dealing with a hardened steel stud broken inside a car frame. I tried cobalt drill bits, titanium drill bits, carbide bits, nothing worked at all after searching online I found a few people claiming tile and glass cutting bits would work well I was shocked with the amazing results from the drill bits

Hey WH Garage - thank you so much for making this video regarding drilling through hardened steel - after going through several "metal bits" you've helped me resolve the problem. Thanks again!

ive been trying with all BS drill bits for the last 4 hours in the heat, i will go buy those glass tile bits, you are a HERO, i hope it works

Thank you for sharing. I just went through the same experience. Cobalt bits - nothing, welding a nut - nothing. But 20 mins of patience with the tile bit and an easy out produced the result. When the tile bit changed its tone I knew we had reached a threshold, I tapped in a Bosch easy out and a 5/16" F150 differential bolt that had been broken for 15 years emerged into the sunlight. Key tips - clean the hole with brake cleaner, then apply cutting fluid. Drill for 1-2 minutes until no more swarf appears. Clean the hole and bit with brake cleaner, re-apply cutting fluid, drill for 1-2 minutes. Repeat until you have a hole deep enough to insert a quality easy out. Top result !!

How long did it take you to drill the hole?

[@wr3ncher]

Masonry bits will work on hardened steel too

[@jgreen3104]

masonry bit with carbide tip?

[@Ben-lw6jf]

They aren't ground to the correct angle, though. They work for like 7 seconds, and then they blunt

[@jgreen3104]

what brand glass tile bit was it. im rendered caless until i get this tap out of this dang hole

[@georgehuffman3942]

These things drill through anything

[@Darth-Nihilus1]

I have a drill bit broke off in the hole and can’t get anything to drill it out, would that work on drilling out a 1/16th titanium coated bit? This has been an issue for weeks now and I can’t complete my project without it getting done 😅

[@biddy98gst]

It will deff drill it out won’t be fast and might need 2 to get it done but It will I used it to drill out a easy out and a cobalt drill bit

[@Darth-Nihilus1]

@@biddy98gst thankfully I only have to drill less than half inch 😅 I will give it a try.

[@leomunoz2422]

Gona try this thanks i got a broken bolt in my subframe any particular brand you used?

[@jgreen3104]

did it work for you?

[@Lantheoneandonly]

what is the product name of that bit that you used?

[@oliverrojas3185]

Viewable on the video, it's a Bosh 3/16 glass tile bit

[@jettschenker]

The glass/tile bit is likely a carbide tip
