We have tons of these Ryobi 18 volt tools - cultivators, blowers, drills, jigsaws, mini chainsaws and more. I love her. I ordered this because our regular Ryobi 18v drill changes quickly, which is great but can't work with round bits. We had to drill some holes in the concrete and these are easier to find in rounds so we needed a new drill bit. Since we already have 3 chargers and lots of batteries (I now buy after sale batteries here at Revain) I went with this simple drill with no accessories. For less than $30 I thought I was right, and I was right. This small drill bit is almost identical to our basic quick change drill bit, but there are some minor differences. This drill is slightly larger and more powerful (you can see it in my photos). It also has torque settings which was really helpful when drilling concrete - we had no problem drilling 28 1/2 holes with this kid! We love it and would buy it again anytime. Now we use it more than our quick change drill.
