Customer name: Chris, from Alaska. Position in company: Owner of family company. Dealing accessories and machines: Rock Drilling Steels, Rock Drill Bits, Excavators, spare parts for rock drilling rigs made by atlas copco, Mitsubishi Rock drill steels and bits. Bits Tested Types: R32-45mm Button bits, T51-76 retrac button bits. Rock information: Extremly hard rocks with abrasive charactors and features. At the begining, we received chris email with descrition of the bits he needed to buy for his client. The bit thread is T51 and the diameter of the bits is 76mm but the body skirt of this threaded bit is retrac, which means it is not normal and usual like everyone else using in some other places. Chris told us that was his client requirement and he had to satisfy his client and gave what his client needed and confirmed this order by sample testing first. We delivered some bits of T51-76 with retrac body skirt, and we did not know that the rock information very well and we had a problem when we received the feedback from Chris, he said our bits could not even bear half of the same bits like Atals Copco and rock more, our bits only drill no more than 200 meters and bits could not be used any more. We had received the photos of the bits and found that bit skirt was almost gone and very bad situation. we realised that our big skirt body is incorrect and no cusotmer would ask for such types, so we asked Chris, he told us the concerns from his client, was to get back the bits because of rock changes in drilling. So the plan we gave Chris was T51-76mm with normal body skirt+Guide Extension Rod to make sure the hole will be straight and clean.
