Transcript HOW MUCH WEIGHT? *echniqu c°^mendations are constantly changing, as bit** oa\o& Weigh* GS are improved. Ten years ago we were reco*^ ^ S °f 3'000 t0 5'000 P°unds Per incn of bit diameter on a the suggested weights, today, on our greatly improved W7R, range from 4,000 to 7,000 pounds. Looking to the future and future weight recommendations, we are experimenting with extreme weights. In a series of research laboratory tests, drilling with a 7%-inch W7R in granite, we applied weights up to 112,000 pounds—equivalent to 14,000 pounds per inch of bit diameter. Frankly, we thought the teeth would snap off. But that didn't happen. Instead, drilling rate and footage increased materially, compared with the performance of the bit with a weight of 70,000 pounds. This, of course, is controlled laboratory drilling... not recommended in actual practice. But the results point to interesting possibilities, in view of our new advanced research program which anticipates increased drilling weights in the future. /ffl^ HUGHES 369
