I ordered this WESCO drill because I was impressed with the performance and build quality of a previously purchased cordless mini circular saw from the same brand; I also want to use 20v lithium ion batteries for these WESCO power tools. The drill itself is strong. The battery lasts a long time. The keyless chuck is very easy to use. You simply screw the bit in place and you're good to go. I used this to drill holes in the wall of my house to install a security camera. It went like clockwork. I would definitely recommend this drill to anyone who wants a lightweight drill for any job around the house. By the way, the whole package includes all the necessary tools and drill bits, great price. Last weekend I successfully drove a screw into concrete plaster to attach a flower rack, which surprised me greatly.
