Our driver tip magnets are an integral part of the assembly which magnetizes the different bits in this portable pocket screwdriver.
We have sold NdFeB magnets since 1996 and N42 grade since 2003, the best value for strength & temperature vs cost. Don't be fooled by claims of higher strength, N52, at lower cost.

We also provide complete Documentation including MSDS & ROHS; see below.
Buy at least 3 and you can do simple levitation experiments if you have a central support. We also offer a variety of sizes of 12.5mm diameter neodymium disc magnets but they are not ideal for levitation.
