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

Got these a few days ago and was pleasantly with how accurate and well made they are. Checked all sides for accuracy and squareness using calipers for size and a combo square for squareness. They seem to dead on accurate, excellent product.

Good enough for wood working but not very accurate and holes don’t line up exactly

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.

Calipers showed it to be at 75.07mm long.

My digital calipers are 11 years old, and have seen a lot of use.

Very sturdy will last for years on end

After degreasing both parts measured to less than 0.001 in all 3 directions in multiple points. Pleasantly surprised.

Great quality for a reasonable price. Well worth the money.

I’ve wanted a setup block for many years and finally decided to take the plunge, I thought I was buying one but to my surprise it is a set of two. Nicely made and will be useful to me.

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