Customer reeivw from the Amazon Vine? Program () For starters, this combo set includes: 1) 20v Cordless Hammerdrill (Model DCD985) 1) 20v Cordless Impact Driver (Model DCF885) 1) Side Handle for the Hammerdrill 1) Charger (Model DCB101) 2) 20v Lithium-Ion Batteries 1) Storage & Carrying Bag 1) Belt Hook (comes attached to the impact driver and can easily be removed) The hammerdrill is what I've used the most and, as expected, it's quite powerful and comes loaded with functions, including a control collar that selects between three modes including: hammerdrilling, screwdriving, and drilling. Of course, the standard torque adjustment collar is right next to the control collar. In addition, there are the standard three speed settings as well as a helpful worklight and an attachable side handle. I use a power drill for home repair projects and this drill is unquestionably the most powerful I've ever owned, perhaps a bit too powerful for the casual user. It's also a bit heavier than I'm accustomed to, coming in at about five pounds (with battery attached) while my 12v Ryobi was less than three pounds. Of course, this DeWalt more than makes up for the slight weight difference as it's a veritable powerhouse. I'll never pick up the Ryobi again! As for the impact driver, there aren't any variable functions, but there is a great worklight included, with the light emanating from three different points on the front of the driver. The included manual indicates that the impact driver chuck only accepts 1/4 (6.35 mm) hex accessories and 1 (25.4 mm) bit tips. Though the belt hook comes pre-attached to the impact driver, it can be easily removed or alternately attached to the hammerdrill. The storage & carrying bag fits the entire set comfortable including drills, charger, batteries and all with room to spare for a few more tools. On the outside of the bag are two 4-inch pockets, one on either side. I've had the drills for nearly a week now and at this point I don't have a single complaint. These are the first DeWalt tools I've owned, but considering the sturdy craftsmanship and overall great performance of the drills, I can certainly say these won't be the last.
