The depth adjuster is movable between a plurality of predefined positions, including a maximum depth of drive position, a minimum depth of drive position, and at least one intermediate depth of drive position. The depth adjuster includes a cam having a cam surface that interacts with the core so as to define an upper position of the core, an adjustment knob operatively connected to the cam, and a detent mechanism for securing the cam at one of the plurality of predefined positions to thereby define the upper position of the core.
