The BORA 4 in. Drill Press Vise is a ?quick action vise? designed for use with all drill presses. The bottom is slotted, which allows the vise to be bolted to a drill table for securing work pieces, and the vise features steel jaws with V-grooves for securely clamping round material. The quick-release action allows for fast and easy setup and adjustments, as well as instant release of your work piece. The handle itself is truly unique, as it locks 90? to the screw for increased torque.
