Kinex 4033-02-015 6 Inches Tall x 4 Inches Wide Flat Solid Machinist Square DIN 875/0 Square to w/in 0.0003 Inches

For the money, great! The finish leaves a lot to be desired but it is only 1/10 the price of a comparably accurate Starrett. I polished the working edges on a flat ceramic stone so I'm happy. Tools at this price point are like kits that you have to finish to your vision of perfection. Minus a star for Taytools listing this as 6"x4". Yes, I get it, that's the normal USA way of thinking about 150x100mm, but they should list the actual size. It's shown in the picture after all. My square's box said "Made in Slovenia" if that matters. Overall I love the one piece design since I can use it like a normal engineer's square AND lay it down flat for use on paper.

I LOVE this square!!! It is solid and well made and extremely accurate. I use it all the time. I also like the extras like a box to keep it in and a certificate of inspection stating that it has been checked for accuracy prior to shipping. I rarely endorse products unless I have complete confidence in them and the company. I highly recommend both, I'm sure you won't be disappointed and will be pleasantly surprised like I was.

The square is just that, SQUARE, however it is NOT 4”X6”. Not really even close. Can not be used for anything except confirming something is square.

This is a great little square. It is well made and gets a lot of use in the shop.

Presentation... Cardboard, triangular.Who cares, this THE square deal.Build your own presentation box

Outside edge are not parallel to inside for about 0.27mm. Because of that its impossible to verify squareness.More than that, the side are not perpendicular to work surface, sort of rhombus in cross section.Both outside edges are not flat as well, checked with straight edge.Had to return. Paid $26.98, they returned $20.06.

Not square! Checked against numerous precision squares with all agreeing that this square is junk! But why oh why am I not seeing the option to add pictures. If I’m going to be critical of a product I like to back up my words with pictures.

Perfect size for calibrating machine tools.
