Retrieval And Metal Testing Magnet. Dimensions are: 2 5/8" overall length (without vinyl cap on), 3/8" diameter handle, 7/8" diameter x 1" tall head, 1/2" diameter heavy-duty stainless steel split ring. Small and very powerful. We have mounted a powerful 5/8" diameter x 5/8" tall cylinder N52 grade neodymium-iron-boron magnet in a brass case for industrial use. It comes with an extra heavy duty split ring for attaching a hook, rope, wire, or fishing line. Here are some possible uses: Identify/sort costume (fake) jewelry, which often uses steel as the base material under the plating. Identify and sort steel grades and metal alloys that contain iron or cobalt. Identify/sort chrome plated items from polished aluminum, silver, and non-magnetic grades of stainless steel. Identify/sort solid brass and bronze from plated steel items (handy in the antique market and hardware store). The magnet insert is rated at 29 lbs (as with all magnets, this rating depends on the magnet mating to a smooth, flat, unpainted steel surface). It holds a 29 lb sledge hammer with rough and rounded edges in mid air with no problems. The brass casing protects the magnet from chipping and breaking, and makes removing iron and steel shavings much easier. A tight fitting vinyl cap is also included to protect the magnet when it is not in use. This also helps keep the magnet from attracting iron dust and steel chips, as well as offering a little buffer to the magnet's strength when it is not being used. Caution: do not store this magnet near cell phones and credit cards. This size is a little too heavy for your key chain. See our smaller sizes for hanging on your key chains. Proudly made in the USA!
