• Bit sizes ranging from 3" to 6-1/4" (76 to 158.7 mm).
• Obtain cores up to 14" (356 mm) long.
• Both closed-end and open-end drill bits are available.

The open-end bits must be used with the expanding adpaters. The adapters are especially designed for fast, easy attachment of the bit to the drilling machine and easy removal of cores that may stick to the interior of the bit.

The closed-end bits include an integral threaded adapter.
