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 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
