The Groove Tech puts a new "spin" on drum keys with a unique sliding "T" handle that allows quick and easy changing of drum heads without power tools. The handle can be slid from one end to the other for extra leverage—especially useful for high-tension drum corps tuning. The drum key's fit and finish is top-drawer, using heat-treated chrome vanadium alloy with a polished chrome finish. The detachable 1/4" drive drum key socket is made to precise tolerances.
