Rated 4.0 out of 5.0 by Impulse Purchases Can Be Good The set is working out really well. We have not broken one yet and that is saying a lot! June 9, 2015

Rated 4.0 out of 5.0 by Great product ! Good enexpensive drills bits with compact carrier. February 3, 2015
Rated 1.0 out of 5.0 by Good price, poor quality I broke 4 bits within the first hour of use. It's nice that they provide doubles of common sizes, but these bits break entirely too easy, dull out quickly, and take forever to drill through metal. Spend a little extra and get a quality set.

Rated 4.0 out of 5.0 by A good value A nice drill bit set. I like that it comes with the 1/2' drill bit, which not many sets do. Also, it comes with doubles of all of your common sizes like 1/8", 1/4", etc. Good thinking, Ryobi! A great deal at $15. August 22, 2010
Rated 1.0 out of 5.0 by Don't waste your money Terrible, cheap drill bits, 3 broke within the first half hour of using them. Don't make the mistake I made, spend a little extra money and buy something that will last. December 29, 2009
Rated 4.0 out of 5.0 by Good band for your buck I found the drill bits to be a high quality material, they were sharp upon purchase, and were even still sharp after several uses. I would recommend this product to other consumers. It is a good quality for the purchase price. August 5, 2014
Rated 1.0 out of 5.0 by not good I broke the first size I needed to make a hole for decking (drilling through composite decking!!!!). So then used the next size that would WORK, and that also broke. I broke two more and then just through the whole thing in the trash. March 30, 2010
