Pro Impact Power Bit Set - 26 PieceKlein Tools has designed a set of Impact Power Bits for the professional electrician. All the bits are made of high-impact rated S2 steel and color coded for easy identification. The 1-1/4-Inch (6.4 mm)long driver bits are easier to grip than a standard 1-Inch (25.4 mm)bit. The bit holder and nut drivers have strong magnets, and are also designed longer so they reach easily into junction boxes. Minimal chamfering on the nut drivers’ hex pockets increases surface contact between the nut and driver for better performance. All 26 pieces fit snugly in a durable, impact-resistant case featuring steel hinges, a stay-shut latch, and a hidden compartment for loose bits. Features:Longer pro impact power bits and drivers are designed to reach easily into boxes and panelsS2 Impact-Rated Steel for maximum life and a 1/4-Inch hex shank4-Inch bit extension with strong magnet to keep bits in place1-1/4-Inch precision machined bits are longer and easier to grip2-5/8-Inch nut drivers reach easily into junction boxesExtended 4-Inch Phillips and Square bits for hard-to-reach fastenersBits are easy to find and fit securely in the storage caseCase has a spring loaded stay-shut latch and a hidden storage area for loose bitsPhillips, square, and combo tips are color coded by size: green- #1 size bits, red- #2 size bits, black- #3 size bitsSlotted tips and nut drivers use ASME standard color codingWARNING: This product can expose you to chemicals which are known to the State of California to cause cancer, birth defects or other reproductive harm.
