From start to finish it took like 3 hours. But a lot of the time was making sure the water doesn’t go everywhere and because there was no close water access, i had to use a manual water pump thingy, which i had to refill again and again. The bits are pretty much all the same, some diamond crown bits. They last quite a long time if you don’t overheat them.
No, the drill is hollow and you pump water through. Also helps to flush out the dust. Except when drilling Aerated concrete or something luke that, then you juat get your bit stuck.
Neat… I always assumed they used the same lube as machining… but I guess you are more interested in keeping the bit cool opposed to the material, where machining is sort of the opposite.
Exactly. Ibalso used like 50l of water for this hole. Pumping in lobe would make a huge mess, and you would have to recycle it, but then there’s sludge in in and so on.
Dude… you’ve got to give specifics. How long did it take, what type of bit, how many, all the good stuff…

You used water for cooling? Not like a machinist cooling oil?

This topic is way too perfect for this podcast : https://www.bbc.co.uk/programmes/p05t3gr2 (BBC - The boring talks)
It’s fascinating.
Fascinating, learned something new today. Thanks, neighbor.
