I have just tried drilling some 3mm thick mild steel with a 13mm
hole......... hell of a lot of noise, loads of vibration and now the drill
seems to do anything but drill!
Ok, please stop laughing, I'm a beginer!! ;)
The drill bit was a Piranna 'Bullet' that it said was for drilling metal,
but what I have only just realsied is that the max recomended rpm for 10mm
was about 1000. The drill was the cheapest Clarkes one speed drill (i'm on a
budget and this might be a '1 of' project) so I guess this is much faster.
So my questions are:
Is the drill running too fast? What speed should i drill 12mm holes at? Does
anyone know where I can the cheapest drill to drill at the recommended
Thanks for any help given
