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.


IIRC, most single speed drills run at about 2400 off load - but you
should be able to slow it down quite a bit on load.


It doesn't slow down enough. I've spent a while blunting bits
with a single speed B and D before borrowing bu FiL's
Lidl special offer with a gearbox which was much easier.
Even a cheap Argos with a lockable trigger is better.
