Review on 🔧 Olsa Tools Bit Magnetizer and Demagnetizer Ring, Magnetic Drive Holder for Screwdriver Bits with Powerful Neodymium Magnet, Compatible with Allen/Hex Keys by Hassan Barrera

3 stars is enough Lack of important information These bit rings can only hold 1/4 inch or small bits or screwdrivers or any other tool you want to magnetize. In practice this means that you can only use my small screwdrivers and bits, which are not very many! Most (80%) of my standard screwdriver shanks are also over 1/4 inch. like most bits that go in my drill. In practice, this means that these "bit rings" are only useful for small "big" electronic screwdrivers, etc. , Sad
