This shank fits Tamrock RD314 drifters in the HLX3/45 configuration, with a 1 in. NC thread and a 13-1/2 in. length. Like the R32 striking bar for the RD314, it sits between the piston and the steel, turning each blow into impact energy the drill string can use.

Confirm the thread on your existing steel before ordering 1 in. NC here and carry it through the rods and bit. The full striking bars and shanked rods category covers other RD-series bars, the buyers guide to drill steel adapters explains how to measure splines and threads, and matching extension drill rods complete the string.
