The DW996 has a center mounted handle that fits the hand quite nicely and balances very well, reducing hand fatigue. The batteries hold a sufficient charge to get the job done without constant changeout and recharging usually is accomplished in just a couple of hours. The hammerdrill feature is quite handy when drilling holes for anchors in concrete walls, floors, and ceilings. It has 3 gears: gear 1 for high torque, gear 2 for moderate use, and gear 3 for high-speed.
