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

Great for checking alignment of sawblades. I check all my 90° setups with these. Belt/disc sander, bandsaw, table saw, use it to guide my pull saw…

... then only a 4 star review.? I dont know about their longevity yet. Rusty threads, dings on the edges and corrosion. Those things will likely happen over the decades, but for now, I dont know.

Works as expected

Très précis !!!

Usable and within the tolerances for wood working. If you are a budding machinist, or someone who is making miniatures, then steer clear of these blocks. The larger the scale you work the better. The finish was OK. Edges look hand filed by someone who could care less. Threading is course and barely passable. No joy in using these, but they were intended to be expendable and used in a shop that is high risk for tools. Should be priced lower because they are a bit high considering how .

According to my digital calipers these blocks measure dead-on accurate! I am impressed!

I got these to help tram and straighten the router and mount on my CNC machine. So far it works great for that and I’ve thought up some other good uses for these things as well. It’s a pretty simple item, and I purchased these as they were some of the most affordable. The quality seems great and they are a great addition to my workshop.

I waited a long time before I had the money to order 2 sets of these. They came in a little oily (for their protection), but a little break fluid cleaner fixed that in no time at all. I have enjoyed using these as I work with miniatures and dollhouses. Perfect for that!

Perfect

I was hesitant to buy these since the price was lower than others. I was pleasantly surprised to find that these 1-2-3 blocks measure perfectly on my calipers. Highly recommended!
