Taytools7464220 Machinist Engineer Solid Stainless Steel Square 6 1/4” x 4” x .220” Thick DIN 875/0 (Square w/in - 0.0003”)

I'm a hobbyist woodworker and I wanted a reference square I can trust. This square came well packaged and as far as I can tell, it looks to be dead-on square both on the inside and outside. Would have been nice if it had a wider base so I could use it for markup referencing off the edge of a board.

It looks very accurate.

The first one was off, WAAAAY off... but this one is dead nuts.Got a replacement in (2) days, not bad.Taytools is always a pleasure, so a fluke part isn't that big of a deal, because I KNOW they intend to have the best products available and 99.99% of the time they hit the mark.

Pretty simple piece of tooling. Came well packaged and protected with heavy oil. Used some Dish Soap and Brake Cleaner to remove. Piece was great and I’ll probably buy a larger one later.

I bought these for use at home around the Mill and lathe. Figured DIN875/0 was good enough and I was expecting it to maybe be a few tenths or so over the stated tolerance. Using a master block confirmed square under 0.00005" in a calibration lab, I squared the... ahem... square to it. With my 0.0005" indicator I got no movement along the length of outer square edge surface for 3/4 of it's length, passed that point it increased slowly to 0.0005" for the last inch or so, I may revisit this again to find the source of it's deviation but it is still plenty good for the $. The inside square surface however, read 0 across it's entire length. Not only are both inside and outside references square. Both legs are parallel to themselves within 0.0001 and even laying on it's side the thickness of the tool is parallel within 0.004" which is not even necessary.Aside from layout details the edges/corners are broken with no Nicks or gouges, surfaces are nicely ground and the company etching is aesthetically pleasing. The box it comes in is made to fit perfectly too!This is an absolute bargain and well worth the price. TAYTOOLS will become a big name if they can keep these prices with this level of quality!

I'm giving this five Stars based on the accuracy of the tool, and the quality of it which seems great. However it shipped in a padded envelope and was contained by a very cheap wooden box case thing, which had broken apart during shipping. But I was buying a right angle not a cheap wooden box so that didn't even really matter to me. I checked the accuracy of this, and it seems perfectly 90°. For the price I consider this a very good value but if you want one with a really nice box you might have to spend a lot more money ;)

Exactly what I was hoping for. Super durable and extremely accurate. If you deal in precision this is for you!!!

As I've upped my woodworking expectations, quality squares have become essential. I have found that some of my older ones were not close even though they looked like old world craftsman's tools. This one is manufactured to a high standard. It makes the setup of machinery reliable because I don't have to wonder if the square is accurate. The only thing I expect of a square is that it be, well, square and this one is very well made. I really like the thickness and heft of it and will likely buy other sizes in this brand.
