1789223 Left Hand Drill Bit, 3/16 In. X 2-3/16 In., High Speed Steel

The Irwin 1789223 is a left-hand jobber drill bit constructed of high-speed steel, designed for drilling and fastener removal applications. Left-hand bits are specifically designed for extracting broken right-hand threaded studs and bolts. This bit can be used with screw extractors for fastener removal work.

High-speed steel construction provides an exceptional combination of strength, heat resistance, and wear resistance, allowing the bit to withstand rigorous drilling tasks in mild steel, wood, and plastic. The 135-degree split point geometry reduces feed pressure during penetration and minimizes work hardening of the material being drilled, resulting in faster, easier drilling with less effort. Whether you are a professional tradesperson or a DIY enthusiast, this bit delivers reliable performance for general-purpose drilling and specialized fastener extraction applications.
