قاعدة مغناطيسية لمؤشر القرص

I needed a quick way to swap my indicator between mill and lathe setups, and this magnetic back threads on securely in seconds. The strong magnet holds tight even on vertical surfaces, and the blue coating keeps it from scratching my tools.

The threads on this screwed right onto my indicator with zero fuss, and once it’s on, that magnet grabs hold of the machine table like it’s welded there. I’ve had it stuck sideways on a vertical surface for hours without it budging an inch.

The blue coating is a nice touch—it keeps the magnet from scratching the surfaces I stick it to. Screws right onto the indicator and holds firm even when I tilt the setup at awkward angles.
