No. Bank vaults are way too thick. But the process is as quiet as the machine driving the bit. They are expensive, though.

its a old upload date, the video looks older as well :P

a video on youtube

You dont understand why this process is used.

I think its made of industrial diamond or ceramic

this is a DC current shortage as like in spot welding

The bit is made of tugsten carbide. Since it is a sintered ceramic of sorts, it can withstand incredibly high heat without any affect to itself. No cutting edge, but they tend to be shaped like a very rounded square rather than a circle down the axis of rotation. Applications are mainly to allow more than just a few threads to be cut into thin wall material.

+Nacho Franc Oh, OH! I know! Nacho Franc?

NobodyNowhereKnowhow Yes!

+Nacho Franc i am ashamed that i know, bro.

+Christoph Schneider You can make room for a screw into a thin metal sheet without welding a nut!

+Rodolfo Agustinho But how is that innovative?

+_404_Error before this, one had to drill a hole, place a rivet, set the rivet, thread the rivet (or pay more for threaded rivets), then secure the rivet in place either with adhesive or a tack weld. rivet and ashesive/weld add extra weight and weak spots. creating the rivet from the existing metal and then threading it creates a perfect bond without the need for any extra weight or work. TL;DR: It takes a 3-5 step process down to 2. That saves LOADS of time, energy, and resources over the span of a project.

I-Love-CO Mountains Then don't use fucking rivets.

+_404_Error Well, fucker, those fucking rivets are fucking necessary, because fucking otherwise there would be fucking nothing to fucking hold the fucking thread. Fucker.

+quirijn van Wingen same hahahahha

+100ignacio100 oooooooooooooooo, aburn.

+quirijn van Wingen me too...

same as the rest of us...

did you pass?

No pienso que venden esto en Latino-America

the point was to melt the metal into the shape it did, in order to thread it for recieving another part. it's actually pretty genius, friction-welding an extra piece out of the existing metal, already bonded in place, no rivets that can come loose as it is already one with the structure. much more area for the threads to grab onto.

+Dax Liniere that'll be a few thousand RPM.

+AlmightyBanger Is that all, do you think? I know that routers run around 15k RPM

i zu golt kafen

Thats cool

+Robert Ritchie there's threaded rivets for that...

+KastaRules right, but this makes use of the existing metal, no need for extra weight (that does matter in some applications), or any more than 2 steps.

+Vita Kupit Right Drill wali dulhainiya.........no way!!

y u cu?

Leo Moralina You can usually clean that up with an old pocket knife pretty quickly

***** spam

Leo Moralina It is not intended for boring a clean hole. It is intended to produce excess material for extra thread surface.

exactly

+BurnerProducts RocketStoves I wonder if the metal around the hole become harder to tap, because it effectively gets heat treated.

Lol how is drilling metal weird

+mike dugan Because that isn't normal drilling, but by melting through the different materials that is listed at below video. Metal drilling is slow process and this is fast, fee seconds per hole. But bad side is that this leaves material around hole so it can't be used so well as normal drill.

im pretty sure they won´t melt and create this effect no

Drill bit.

Drill Press

Flo-Drill is one brand I have used.

This process is not to merely drill a hole. Thermal drilling is almost always employed to provide an extended surface for threading, in thinner material, eliminating the need to weld a threaded nut, for fastening.
