Rated 3.3 out of 5 by 23 reviewers.
Rated 1 out of 5 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 out of 5 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 4 out of 5 by Great for home projects Lots of bits and the sizes I need for around the home and property. Economically priced and a good value. June 25, 2014
Rated 5 out of 5 by Great product at a great price I was looking to replace a certain size metal drill bit, and for the great price and excellent quality of the set, I couldn't help but buy this instead! May 8, 2014
Rated 3 out of 5 by 2nd time I bought this set They work well, it just seems nothing lasts as long as I did in the past. Don't hold an edge on reshaping. Inferior steel ... possibly, sell more product, definitely. April 29, 2014
