Good quality. It doesn't have a carbide tip, and that doesn't mean it has a carbide tip. This is a bimetal, good for wood as long as you don't overheat the drill bit by applying excessive force, and for soft metal. Not suitable for stainless steel.
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.
