Aspaton 123 Blocks 23 Holes 1 2 3 Block Within .0002" Tolerances 3-2-1 Blocks Set Used for Calibrating Equipment

High quality 1-2-3 blocks for being an import. I don’t have measuring instruments for check anything small than. .0005” and these are within that. Accurate enough for everything I need.

Great addition for my weld fixture table, yeah I'm sure all the machinists are whining...

Perfectly squared. Works great for the project I'm working on

These have been used much more than I envisioned. Simply having blocks of known dimensions to prop material, or to use as a quick measurement tool. Simply has been a useful, inexpensive, really useful tool.

the finish was sorta coarse like a brushed surface, no reflections here. the threads on the threaded holes are shallow and not well defined. the two blocks are not matched. one was right on and the other slightly under but still within +-0.0005 using cheap calipers. the corners are bevelled unevenly and with significantly different coarseness. for woodworking and non mission critical machining they are fine. i didn't check hardness except for that a s2 hardened screwdriver bit wont scratch it.

Great for woodworking

Perfect but a hell of a time cleaning lol

Need things straight from my for a project
