I will compare 2 sets of 81 pieces gauge block ( Jo-Blocks ), one is a Webber brand distributed by Starrett to another one distributed by Fowler, we'll discover that for the use in a small shop or for home use they will both do the work.

Companies like Starrett, Mitutoyo, will sell some of the highest quality sets to supply laboratory grade blocks for the highest precision.

Companies like Shars, accusize, and a few more companies are selling affordable sets.

Since I was unable to tell a real difference, even if in reality the difference does exist, it's beyond the ability of a small shop to measure those tiny variances.

In conclusion, for use in a home shop or a small shop you can get cheaper set and get the job done... If you do research, avionics, military, etc that requires certified metrology tools, then you need to get the high end and have it certified on a regular basis, this is another ball game...

Thanks for viewing and I hope you enjoyed, please subscribe, comment and like....
