This seems to be much easier than doing it with a tap wrench

It is much easier and faster, especially when you are tapping a lot of holes.

cordless drill, or drill press works perfectly to thread, if you're a little carefull :P

i tried out our new portable magnet base drill at work the other day.

ended up drilling and threading 24 M36 holes with it. at about 8minutes per hole.

works quite well, but it's a lot of work drilling with manual feed.

I have never tried the mag drill for this, but I'll give it a go when I get chance.

Thanks for the comment

@ultimatehandyman with a normal sized mag drill you might be able to do M16 maybe M20.

i have a video of the machine we have at work threading M36.

that machine is the biggest portable mag drill available worldwide.

it is capable of drilling 200MM diameter and tapping M52. and we have machine number 1 and 2 :)

What is funny about it?

Always wanted to know how to do this because a lot of items that need mounting to floors need this type of fixing. EXCELLENT WORK

Detail must be strong fix.

@ultimatehandyman hmm.. material? more cutting fluid? cool! honestly.. why i didnt think of that? thanks! i appreciate it! :)

@izaatmusic

The only thing I can think of is the tap material. A lot of people on here use carbide taps, but I only ever use High speed steel or Carbon steel which may be less brittle than carbide? Also you must use planty of cutting fluid!

I can honestly say that I have never broken a tap using this technique as the torque control on the drill should not allow it.
