WEN 10423 3 x 2 x 1-Inch Steel-Hardened Precision 123 Blocks, Two Pack

As I said very useful for general blocking but now I really want a more precise want a 1,2,3 cm set ..

I ordered 2 blocks.

They are working

With my equipment I measure them to be nominal +/-0.0005in

dont trust all things made in China, my rulers are not accurate. These Blocks measure up to good precision

They work perfect! No issues

The 1=2=3 Blocks look good and are accurate enough for my work.

These 123 blocks are cheaply made and not suitable for more precise work.

I love my setup blocks, I use them for setting up the table saw as well as router table. Having something that is a known size is very handy and these are well made and look like they will hold up very well.
