REMS Diamond Core Drill Bit:UDKB 125mm x 420mm x 1 1/4"UNC Female

This diamond core drill bit is a precision tooling component designed for the extraction of circular cores from construction materials such as concrete, stone, and masonry. The bit features a nominal cutting diameter of 125mm and a total nominal length of 420mm, providing the reach necessary for deep core drilling applications. It is engineered with a 1 1/4" UNC Female thread series to ensure a secure and compatible connection with standard rotary hammer or drilling rig shanks. Buyers select this specific bit when their equipment utilizes UNC threading, ensuring operational continuity and reducing the need for additional adapters during on-site work. To choose the correct tool, verify that the bit’s thread type matches the drive mechanism of your drilling machine and that the 125mm diameter aligns with the required core sample size for inspection or utility installation.
