Figure F19 (continued). E. Smith 9 inch tricone bit used for Run 7 to successfully clear the obstructed interval at 922–923 mbsf and work several ledges before reaching the bottom of the hole on the morning of 1 May. The bit was slightly out of gauge after 32.8 h of use. F. The worn core catcher used during Run 9, the first coring run of Expedition 335. As drilling continued for ~10 h with a destroyed bit (G, H), the core catcher was in contact with metal/junk and/or rocks; it is ~1 cm shorter than the new core catcher on the right. G, H. Remains of the Ulterra C9 RCB coring bit used during Run 9. The bit was probably used for ~10 h after it disintegrated, which resulted in this spectacularly abraded and sculptured bit (“Stumpy”), something never seen before by the drillers.
