Bake Hughes advises the original plan to ship the DSATS bits out during the first week of April remains unchanged, although there is a possibility to get them out sooner. For those of you who purchased bits online for testing your rig design and basic control techniques, please share a link to the supplier you used. Any comments you have about the quality of the bits you used would also be appreciated. Just leave a comment below.

Missouri S&T bought our bits from Shandong TOPS. sdtops.com. Haven’t had any problems drilling with them but they do have some surface rust on the unused bits after ~9 months. I guess you can’t expect too much from an $11 drill bit. Our contact is Xichun Jia ( xichun.jia@ sdtops.com) and was very helpful.
