Stepped drag bits are a type of drill bit used for drilling holes in soft to medium-hard formations such as sandstone, shale, and clay. These bits are designed with a stepped profile, which means that they have different sizes of cutting elements placed at intervals along the length of the bit.

The cutting elements on stepped drag bits are typically made of tungsten carbide or diamond inserts, which provide high wear resistance and durability. The stepped design allows the bit to penetrate the formation more efficiently and reduces the risk of getting stuck in the hole.
