IRWIN Tools 1882442 Impact Performance Series Irwin Quick Change Extension, 1/4-Inch Shank, 2 1/2-Inch Length

IRWIN Impact Performance Series Quick-Change Extensions are engineered for maximum durability and long life with impact drivers. The quick-release system guarantees fast bit changes, and the patented jaw design is compatible with all 1/4" hex shank accessories, including insert bits. These extensions have a large chuck that withstands the high torque of impact drivers, and the black oxide finish resists corrosion and increases life of the extension. Plus, the 1/4" quick-change shank works with impact drivers and reduces slipping in standard drill chucks.
