Irwin 62112ZR 3/16" x 12" HSS Aircraft Extension Fractional Straight Shank Bit (3 Pack)

Ideal for applications requiring an extended reach. Made from premium M-2 high-speed steel for increased durability. Black oxide finish resists corrosion. Not recommended for deep drilling applications. 135-degree split-point tip starts drilling immediately with less force and eliminates "walking" across the work surface.
