The RUFFY 2000™ is a general purpose wood boring bit. Designed for use with hydraulic, electric, or pneumatic driven power tools. The spear point cutting tip design allows the RUFFY 2000™ to be used in applications that require a bit that is not self-feeding such as in a drill press. The 7/16" or 5/8" hex shank enables the RUFFY 2000™ to be used in power tools that have a quick change chuck or even a three-jaw chuck.
