Foudation rock piling application always use thirds(1/3) of tri-cone bit, the single roller cone cutters is welded at rotary drilling bucket directly, after cutter wear out, drillers cut the used ones down and re-weld new single roller cone cutter, cutting and rewelding is a slow procedure. After developed the square arm single roller cone cutters, replaceable single roller cones was developed at the same time which is much convenient for projects in remote areas, drillers can replace a new single roller cone cutters simply and rapidly. Welding single roller cone cutters sometimes heat the bearing and always damage it in welding procedure, welding holders other than roller cone cutters could prevent bearing heat too much before drilling. We have two types of holders, one is vertical and fixed by bolts, another one is horizontal and fixed by split pin.Features of C133 series Single Roller Cone Cutters for Piling Bucket Drills
