The LENOX 33112LL112 is a self feed drill bit designed for fast, aggressive boring through wood framing, engineered lumber, and similar substrates during rough-in work. It accepts a 7/16 inch hex shank for secure chuck engagement and delivers a 1-1/8 inch diameter cut. The bright finish steel construction keeps the bit durable across repeated use. At 5-1/2 inches overall length, it reaches through standard framing members without an extension.
