I have one mounted on the front edge of the bench on my small lathe to hold small metal items...knockout bar, a small pair of channel locks, tommy bars, etc. On the other lathe I have two of them mounted on the front of each leg, also for such small items including my mandrel. The tools themselves are in holes drilled in a wooden 2x6 mounted lengthwise under the lathe between the legs. I was afraid of knocking the tools off the magnet strips and ruining the edge on the concrete floor. All together, I have about six of the magnet bars in the shop and two in the kitchen where I store the blades for my food processor, metal tongs, can opener, etc.
