Like. (Like button gone walkabouts.)
That happens with me as well. I need to press F5 to refresh the page to make the button reappear.
I have to use that F5 so much on this forum that the lettering has almost worn off it!!!
Related question - I owe you guys a lot! Do you cool an SDS bit with water when in use? I quickly took to doing that with ordinary masonry bits after bending and 'untwisting' a few! Might help with the dust in motor issue as well...
Use a plastic carrier bag to stop this.
I never did. I think you could make the overheating problem worse by turning the concrete / brick dust into mud which would clog the flutes of the drill.
If yo have to cool it I would suggest a steady blast of compressed air, but then you're getting into problems of where to get it from and the dust that will be flying around.
Your problem with "ordinary masonry drills" is one of speed - you were running it too damned fast! Slow it down a bit and let the drill bit do the work in its own time.
If you want to be a real clever shyte, you can calculate how fast you should be running the drill bit at from the formula N= 12xS / Pi x d
where: N= spindle speed in RPM (this is the bit you're trying to find out)
12 is a constant (cos this formula uses imperial units)
S is the cutting speed of the material (brick or whatever) in feet per minute
Pi is 3.14
d is the diameter (in inches) of the drill.
There is a metric variation on this but I could never be arsed to learn it.
