Here you'll find a list of what I find the best cordless drills collection from a General Contractor's point of view.
The Makita XT248 LXT 18V Cordless Lithium-Ion Brushless 2-Tool Combo Kit is one heck of a cordless drill to buy and is my number#1 favorite and a recent purchase of mine, coming from the old "Dewalt XRP model" in which lasted me nearly 10 years of solid abuse!
So, why did I buy this drill? Partly, I just wanted to try a different brand and the reviews I read online were great. Best of all, I really like the grip on this cordless drill and the lower RPM speeds for better control. Also, the biggest plus in buying this drill was the quick and long lasting batteries! My last drill set didn't have Lithium-Ion batteries.
