Magnetic Base,Suitable for Magnetic Machine Lights,Indicator Holder Metric M8 X 1.25 Tapped Hole,4.72x1.96x2.16 Inch,1 pc…

The 12T is a good solid base. Very happy with the purchase. I just used it for an LED light upgrade, which had come with a smaller base. The modified light now sits solidly on the side of my lathe. The upgrade took me a while to figure out, so I'll share what I learned.Previously, I purchased an LED light with the smaller magnetic base, but it was insufficient for my use case: attaching the light to the side of my lathe. The light kept falling off. So I ordered this 12T base which has significantly more holding power.I unscrewed the LED light from the smaller base, unfortunately my light had M10 (approximately) threads. So I bought an M10 (female) to M8 (male) adapter (look for motorcycle mirror adapters). The male M8 end fit solidly in the base, but the screw was too long, so I shortened it using a hacksaw. Otherwise you risk interfering with the magnet’s internal lock/unlock mechanism.The female M10 end, which attached to my light was close but not perfect. (Maybe a fine vs. coarse thread issue?) So I smeared two part epoxy into the female end of the adapter and then screwed in the LED light tightly. The connection with the adapter is now very solid.When I screwed the light into the base I put a dab of superglue on the threads of the M8 adapter so it wouldn’t come loose from the base when I adjusted the light. (just a dab, be careful to not get superglue into the interior of the magnet or you could freeze the lock/unlock mechanism.) Pretty sure I could use acetone and/or a wrench to loosen the superglue if I ever need to get the light off the base, but I haven't tested this.As I said, it took me a while to figure all the above out. It isn’t bad as it sounds. To do it again would take a few minutes, so I’m sharing here for the one or two people who are trying to do something similar :)Finally, I’m not sure if these bases can be found with holes other than M8, but you might want to seek them out, if needed for your use case. I could have avoided a lot of hassle if I just found a base with the right size hole from the start.

Great value for good quality equipment.

I use this Magnetic Base for holding clamps for aligning tools

This doesn’t have the holding power of nearly what they claim! I tried it on 1 inch plate because they claim it requires 3 cm of substrate to reach it holding power. BS. I could still pull it off by hand and I promise you I cannot lift 200 pounds with my hand. I am tired of these companies false claims they just leads to inconvenience and further expense to label box and return. I live in the country. It’s not like I just walk next door.

The links are metal. When you actuate the lever at the bottom it pulls a cable through the links tight which makes the whole thing very rigid. Tension is adjustable. Really nice. The dovetail mount fits my indicators. Magnet very strong.

This works well with smaller arms, lights, etc. The longer the arm, the more torque and the easier it comes off. The mechanical switch makes engaging and disengaging easy, especially operhead (I use it for battery powered lights.)
