About Colton Industrial Tools

Magnetic 1-2-3 Blocks, Ultra Precision Matched Set

1-2-3 Blocks are a common shop set up thanks to their versatility. Machinists, woodworkers, metalworkers, welders, and other makers have myriad uses for 1-2-3 blocks as they can work both as a support and gauge simultaneously. 1-2-3 blocks can be used to calibrate equipment, space your jobs, collect measurements, or support your work. Colton Tools has taken the 1-2-3 blocks to another level with their magnetic version. Each of the 3 different faces has two powerful rare-earth magnets that are inset, keeping the face of the blocks flush. These magnets increase the speed of setup and the versatility of standard 1-2-3 blocks. The rare-earth magnets have a pull away force of 35 pounds on 1" steel and this Colton Tools set includes four extra magnets, four set screws, a case, and a hex key. Another example of how Colton Industrial Tools is “Helping Makers Make Better."

Magnets are weak and brittle, break easy and don’t hold to any surfaces. I would have to take the hole deeper and add two of their horrible magnets to make it work. And get a longer screw of course. For 50 dollars it’s a rip off.

These are well made and accurate. My only complaint is the magnets are not strong enough to hold the block to a vertical surface which was why I wanted this set.

Magnets cracked the first time I moved them to a new spot.

If you think this set think again choose anything else.

Don't waste your time. These are Chinese junk. They won't hold to a single thing. Biggest waste of money I've spent so far "Chinese garbage "

Magnet weak can’t even hold themselves on the fridge.
