Decided to turn the drill off but couldn’t see the writing in it which said “ electromagnetic “ . Shit me up a bit when it fell …. ?

I’m working around stuff as we live on site I.e everything gets in the (expletive deleted)ing way . If a complete empty room I could probably do 20 holes an hour maybe by pushing the bit in harder and not fannying around .

EDIT., oops, just re read that , not 3/4" inch..   It will depend on diameter of hole, and number. but you can get some  good results with metal hole saw

There are goggles that fit over specs. Worth looking for. I think mind came off some official "look at our project" site visit.   But where are they?

something that will get through a 3/4mm steel plate without taking all day as the cheapo stuff I have is currently taking? thanks

Before anyone asks no where to tie drill to in event of this or power failure . Anyway who wants a 20 kg drill swing into their face .

Slow speed so you don’t burn it up. The bigger the hole, the slower the rpm - it’s the surface speed that’s key. +1 for coolant/cutting fluid. Also clear the chips if they’re building up. Rotabroach / annular cutter if they’re not tiny holes.

The only own-brand or barely known names i would buy would be for a contractor who forgot to bring any bits, esp for concrete, but i get some to keep him on site. I won't be seeing them again, and don't care.

I am just about to buy a new set, as my old ones are pretty knackered, after a bit of research I am heading for the following. We will see….

Yeah , I’ve got a full face mask ( fine with glasses ) but steams up in 1 second . Done the other holes now . Once each is done ; I leave the drill and magnet running then change glasses . Tbh I think even blind folded I know which switch not to touch .

D-Link DAP-2660 v1.13 was discovered to contain a buffer overflow via the f_ipv6_enable parameter at /bsc_ipv6. This vulnerability is exploited via a crafted POST request.

Any HSS drill bit will do it, as long as it's a real one, not cheap Chinese ones. The import bit is applying the correct pressure, this doesn't come from a hand drill, unless you are drill small holes.  You need coolant also.

There was similar thread a few weeks ago, the OP ended up (after breaking / chipping drills) renting a Mag drill and cutter.  At the thickness your talking about this is the best way to go. otherwise the drill will snatch, chip etc or brake your wrists....
