If you need extra reach for drilling in lumber, joists, or thicker stock, the SMJXTOP 1/4″ x 9″ auger drill bit is built to help you bore clean, consistent holes with less wandering at the start. Its self-feeding, coarse-threaded tip is designed to pull the bit into wood and center quickly, which can be especially helpful when you’re starting holes on rougher surfaces.

Made from 1045 high carbon steel and hardened for durability, this bit is designed for efficient cutting and smoother results. A single-spur cutting edge scores the outline before drilling, while large, deep flutes move chips out fast—helping reduce clogging and keeping your hole cleaner. It features a 1/4″ hex shank for a secure grip in compatible chucks and is intended for use on wood and similar materials (not metal).
