wow , info overload. at work, Diamond drills- exploration mining we sometimes have to dry sharpen our bits, we use diamond bits hence the name, at depths over 2000 feet it is real tricky and the oppertunity to f up is huge, hyd. delay, rod stretch (2" for 1000 feet) etc... so I get the guys to drop a segment from an old bit down the hole and as it gets cut up it will strip the bit on the rod string.
What is it made of, Diamonds, synthetic diamonds, carbide and tungston dust, carbide inserts and yes they are heavy.
Reason I asked this question was for timing purposes, when we drop the segment how long would we wait before we dropped a piece of our drilling equipment that is regulated to fall at 100 ft./min, will the segment fall faster than 100ft. per minute?
