DTH Ring Bit Set for Casing Advancement
DTH (Down-The-Hole) ring bit sets are advanced drilling solutions designed for casing drilling applications. These systems ensure efficient and precise drilling while enabling the installation of casing tubes in various ground conditions.


Large ID Ring Bit Systems
Tri-Mach’s Large ID Ring Bit System is designed for use with sacrificial casings in situations where drilling needs to continue beyond the casing depth. This makes the Large ID system an ideal choice for energy and water well drilling, where operations proceed through the installed ring bit using a smaller rock bit. In piling applications, the system also enables the drilling of full-size rock sockets through the ring bit with large-diameter rock bits, ensuring efficient continuation and maximum borehole diameter after the casing is set.
