Kinex squares

Kinex squares are a fantastic value. Not well known to U.S. woodworkers, Kinex’s website states, “Swiss quality made in the Czech Republic.” Their tools are made to German DIN standards for accuracy. That’s the Deutsches Institut für Normung, which just sounds accurate to my ears.

Their all-steel “Precision Universal Squares,” which are designed much like a regular try square, are available in DIN 875/1 or the even stricter DIN 875/0. Each square comes with its own signed inspection certificate.

As examples, a 150mm (6″ blade) square in the DIN 875/1 standard has a deviation-from-right-angle tolerance of .018mm (.0007″) and costs $15.99 on Amazon, sold by Taylor Toolworks. The 150mm DIN 875/0 has a tolerance of .008mm (.0003″ – about a quarter thou!) and costs only $19.99. You can also order Kinex tools directly from Taylor Toolworks.

The handy 100mm x 70mm square (model #4026-02-010, DIN 875/0) that I bought is nicely balanced, and well finished with all edges relieved. There was a tiny nick on the blade and a tiny burr at the end of the blade, both of which I easily removed with a fine diamond touch-up hone. There were also a few insignificant surface scratches.

I cannot truly assess this level of accuracy in my shop but testing against my Starrett showed virtually light-blocking consistency in all parameters. I’m happy because, as someone quipped in an article that I read somewhere, long ago, “I like to be the only one adding inaccuracy to my work.”

Kinex makes other models of squares – flat, stand up, knife-edge, large, and lightweight – and an extensive line of other precision tools. As far as I know, Kinex squares are not sold by any traditional or online woodworking stores in the U.S. except Taylor Toolworks. Kinex has an online store but shipping is from Europe.

As usual, this review is unsolicited and uncompensated. I have no relationship with Kinex or its distributors.

    I’ve ordered a few things from Taylor tool works over the years, with decidedly mixed results. I have a double square that was listed as a second, with a premise of only cosmetic blemishes, and it was significantly off square checked against my friend’s cylinder square (after finding it didn’t match my older starrett I wasn’t sure how much to trust the starrett itself, though it was clear the one in question was off from the draw line, flip, draw line, compare check. Old one was still spot on, turned out) . Can’t recall how much but was way too much to use as is, and I had to shave the lands to true it. I have them another try with a machinist square, not blemished, and was sent one that literally had not been made right – obviously never inspected. In one instance, parallel faces were not even parallel, like it wasn’t give the full machining.

    I would like to assume it was a rare instance of something slipping through the cracks, and he took it back with full refund just as the listings said, but offered zero comment or explanation when I asked about the issue, simply gave refund. This left me with the sense that you get what you pay for after all.

    There’s a reason precision is not cheap, and while for woodworking you don’t need extreme precision, neither item was a viable tool as shipped, and neither met the listings’ claims.
    Hopefully, and the reviews seemed to suggest this when I last looked long ago, that it’s a matter of bad qc rather than overall bad manufacturing, but check what you get.

    Hank,

    You did not mention the brand of either square that you bought, so I cannot draw any inference about Kinex squares from your comment. Regarding the first square, you say that you had to “shave the lands to true it,” so I guess it was an adjustable square. Taylor does not sell an adjustable Kinex square.

    It’s good that Taylor refunded your purchase without question. They have a 100% favorable rating on Amazon.

    I have no relationship with Kinex or Taylor.
