IRWIN Tools 1899800 Impact Performance Series Power Drill Insert Bit Holder Magnet with C-Ring, 12-Inch Length

IRWIN Impact Performance Series insert bit holders are built for maximum durability and long life with impact tools. They have a c-ring design with an external clip that fits into the retaining ring notch of the insert bit and a powerful rare earth magnet - both of which hold bits securely in place. They have a black oxide finish that resists corrosion and increases the life of the bit holder. Plus, with a 1/4" quick-change shank, they're designed to work with all types of impact drivers, and also fit securely in standard drill chucks.
