Shank adapters, couplings, extension rods, threaded cross bits and threaded button bits belong to threaded drilling products. Shank adapter is used for transmitting power between drill machine and drill stems.
One end is to connect drill machine, another end is to connect drill stems, by this way, the power from drill machine is transmitted to drill bits, and finally the rocks are cut. In the world, there are different drill machines, so different shank adapters are available, like atlas copco, tamrock, ingersoll rand, etc. Also for the same drill machine, due to different applications, the shank adapters can be different length and different threads. Maxdrill shank adapters are compatible tabert,

Male/female (m/f) rod, speed rod
M/f drill steel is an alternative to couplings sleeves to include the female part of the threaded connection as an integral part of the drill steel. M/f drill steel provides more rigid connections and is easier to uncouple and handle. The service life also tends to be better than with separate couplings. The advantages of drilling with m/f steel include: easy handling, quicker uncoupling, tighter connections, the potential to drill straighter holes, and longer service life.
