Concrete Bits, Core Bits, & Rocky Soil Screw Augers
Screw augers are used with rotary hammer drills to penetrate hard soils, asphalt, and concrete. They have extra large pilot tips, and include a built-in SDS-Max or splined adapter. Concrete bits are made for fast, accurate drilling with a rotary hammer drill. Concrete and wild bore bits are one-piece bits, while concrete core bits include a core body, SDSMax or splined adapter, and a starter or pilot bit.
