Bulk orders will be discounted, please contact us.

These individual core bit heads come with a center pin and require a compatible adapter or extension to install them on a compatible rotary hammer drill. A variety of adapters and extensions can be used with the heads, which allows them to be used with a wider variety of rotary hammer drills than one-piece core bits. The heads create large, shallow holes in concrete, masonry, and limestone.
