Pro-Grade 2-in-1 Quick Change Magnetic Bit Holder Hex
This top-of-the-line driver bit holder covers you two ways - cam lock collar for quick-change bits (ones that have groove on shank like this holder) plus a strong magnet to keep non-quick change bits in the holder. Fits any hex screwdriver, security, TORX or other type bit with 1/4" hex shank; use in 3/8" or 1/2" drill chucks, impact drivers or driver handles. We suggest ordering more than one - this is one of those well-made & effective tools that gets borrowed permanently by friends & co-workers.
