I buy one of these every year because I abuse them. The Lenox is the best there is and at this price you can't beat it. Also for those who don't know. The Lenox has a larger tooth span, so the bit doesn't bind as much when drilling holes in thick wood. I bought another brand as a last resort and found in hindsight that this is a big problem for most other brands. I will only buy lenox from now on.
