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.
