Quality magnet, worth the price.

Work well with quick shipping

I used this magnet to hold a bracket while I welded it to my trailer and it worked great. Super happy with it.

The little magnet works well on sheetmetal. However, I was anticipating one a bit larger in size than this. I do welding on plate an inch thick at times so I will have to try the 600lb and up next. But this smaller one is awesome like I said for smaller plate metal.

I am very satisfied with this purchase. It is somewhat expensive but in my opinion you get what you pay for. This is the second one I have purchased of this size. It has great holding ability and can be used in most case with one hand. I do a lot of metal fabrication and I use this size and some smaller regularly. The old one still works it is just difficult turning the handle with one hand due to years of use.

Not sure what it is about magnets, but I sure like them. I'm sure it has something to do with their ability to simplify problem solving. These switchable magnets are some of my favorites. Not only do they work really well for squaring up materials, but they perfect for jig making. I have several woodworking and metalworking jigs that require the use of thee magnets, and with their threaded holes, there are many more things I'm able to do with them. as far as hold strength, I'm not quite sure they have as much holding power as they tout, but they have plenty of holding power to keep my jigs stationary.

Most of the pictures shown are not from the actual item model but from other larger models, so you might get a bit mislead. The magnetic hold power does not fast enough to be dependable if lateral force is applied, therefore it cannot be used as a stop block or fence jig.

I should explain that I did not purchase this for its designed purpose as a welding return ground. I purchased it to be used as a temporary measurement ground on a metallic ground plane in an electromagnetic measurement laboratory.In the function above, I need a very low resistance attachment point on a sheet metal ground plane for measurement return purposes. This attachment point is ever changing, so the magnetic approach is perfect.For the purposes above this clamp worked perfectly. It’s easy to move and attach, offers a good wire connection surface with threaded holes, and provides a very low resistance point to the ground plane (20m).Worked perfectly for my unique usage.
