The standard duty Rotojec shank pairs a precision-machined 3 in. OD shank with a 4-3/4 in. OD body section to connect a drill to a grout injection string, transferring torque and impact while grout is introduced through the matching Rotojec grout injection body. Closed striking bar ends come in C64, R32 to R38, H55, H64, T38 to T51 and TTN40; open grout bar ends run Rf32 to R76, T38 to T51, TTN30, TTN40 and X32 to X51.
Hardened steel construction handles the combined impact, rotation and abrasive slurry of soil stabilization work foundation and piling drilling, micropile grouting, anchor installation, and mining and utility applications. When the job calls for more section, step up to the heavy duty Rotojec shank, keep spare Rotojec seals on hand, and match the rest of the string from our drill steel & bits range.
