Im sure that in my previous web-wanderings I came across an
article/page which described milling, and said that a slot drill is
basically a normal drill sharpened differently.
Of course now I need this information I cannot find it... so can anyone
confirm this, or point me to a place that can, or even give me pointers
on how to turn said drill into a slot drill.
Its for some ~ 1mm slots in brass, and given I dont need to do many,
and 1mm slot drills are =A38 ea, but 1mm drills are about =A31 for 5
there is a reasonable incentive to use drills, especially as I have
some snapped 1mm cobalt drills with a bit of helix still on them.
