Rated 3.8 out of 5 by 40 reviewers.
Rated 1.0 out of 5.0 by Save your money and time. These bits do not cut at the countersink. When used in hardwood, they just burn-will not cut. I'm returning them to the store. February 6, 2010
Rated 1.0 out of 5.0 by Not good! This might work with plywood, but if you're planning to use it on hardwood - don't bother. The countersink doesn't cut into the wood easily. I tried this on Maple, Cherry, and Oak and it simply didn't cut into the wood without a lot of force, and then just barely. I already threw this in the garbage. February 3, 2012
Rated 5.0 out of 5.0 by Does what it claims I had previously only used a cone-shaped countersink out of one of the drill and driver bit kits, but I didn't put it back last time. This one had 4 different sizes (and I didn't know which one I needed), and was the cheapest of the bunch. The pilot bits are short, but they are removable and replaceable with the included hex wrench. They have the quick change hex shank on the bottom, making the switch from drilling to driving quicker. Downsides are the short pilot bits, lack of any sort of case to keep the set together, and no mechanical stop to keep you from drilling the counterbore too far. Despite these, for the price, it's a buy. June 10, 2014
Rated 3.0 out of 5.0 by okay but troublesome to set When the bits work, they work well. However, they are a little troublesome to set for depth and on more than one occasion, the allen nut would slip and the bit would come out regardless of how hard I tried to tighten it. In fact, trying to tighten it harder just made the allen wrench slip out of the nut. February 17, 2014
Rated 5.0 out of 5.0 by These bits last forever Product works great. I used my first set 5 years and recently purchased another because of misplaced/lost bits. The only problem is the quality of the set screw March 4, 2014
Rated 4.0 out of 5.0 by Just what you need for a power driver!!! I have had several counter sink bits, but never seemed to have the right diameter for what ever gauge screw I was using. This set covers most screw sizes that you would use on wood. Very good performance. February 25, 2014
Rated 3.0 out of 5.0 by Ok, not great Good for occasional use but not recomended for projects that require mumerous holes. I have used on both soft and hard woods. They work good on shallow countersinks but really load up and burn on deeper countersinks where you intend to use a plug to cover the screw head. It's a typical Ryobi product .... ok, not great.

Rated 4.0 out of 5.0 by contersink bits worked great and are adjustable. the contersink size was the right size for the screw head. August 26, 2014
