Abstract
Disclosed is a fluid actuated core sample holding device for use with a boring drill press, the holding device having rotatable vise jaws and flat support surfaces adjacent the respective jaws and containing removable holding pins. The rotatable jaws permit a greater versatility in the positioning of core samples held between them relative to the drill press, while the flat support surfaces and associated holding pins serve to hold flat or irregularly shaped core samples, not easily held by the jaws, for boring.
