This magnet is so strong that it will hold a screw on a 6" long bit.
Are you dropping screws off the end of your power tools? Are you driving screws into a blind hole and can't find a long enough magnetized bit? Then we'd like to introduce to you our new "super magnets". These magnets are made up of neodymium material and are proven to be up to 3 times as strong as ordinary alnico magnets.
Neodymium magnets (actually an alloy, Nd2Fe14B) are the strongest permanent magnets known. A neodymium magnet of a few grams can lift a thousand times its own weight.
