Anchor drill bits are used as consumables for drilling, and can usually be divided into two types, alloy drill bits and all-steel drill bits, which are produced by machining or casting production processes.   Thread specifications：R

The self-rotating anchor coupling sleeve is used to connect the bolt to achieve the function of a specified length.   Thread specifications：R25, R32, R38, R51, T30, T40, T52, T73, T76, T103, T111, T127, T130

We all know that when a large diameter drill bit is connected to a smaller size bolt, it can affect drilling performance, so in an anchor drilling operation, a self-drilling anchor bit converter is required to connect the large diameter bit to the smaller size bolt.
