📐 Machinist Mechanical Engineer Precision Measurement Test, Inspection & Gauging Review

Exactly what you expect from a well-made precision machine tool. Essential for jewelers and tanners, highly recommended!

Looks like they use heavy fuel oil to prevent rust. But the item must be left open to collect dust and dirt on the floor. The tool is dirty. With a small scratch, the item does not look new.

I like the price and the plastic case but ultimately it's useless because it's inaccurate. The 90 degree angle from the handle to the blade is closer to 85 degrees. Maybe it was a one time mistake. I forgot to return it in time so it will be the doorstop now. A reminder to pay more for quality.

I use it for woodworking. I have many squares that are not necessarily square. After testing this I use it to test others. I also use it to calibrate cutting angles on my table saw and miter saw. It's small enough to carry in my pocket and I like being able to slip it in a pocket when I'm done.

I see with my own eyes that this product is not square, you can even see it in the picture. It's close to a degree outside the square or more. The parts don't fit together properly and there are marks of someone doing the finishing on a bench grinder. Very disappointed you could probably get a woodworking square in port freight and that would be more accurate.

easily and firmly. Since it's so small it's quite surprising that it's so crooked... I haven't measured it yet, but compared to 4 with the other squares I have around it, it came out at about 32. out after just a few inches around the same amount on each one so I'm pretty sure that's the one that's out.... Pretty useless I'd say and not worth going back... I'll test it with my precision instruments at some point, but even on a speed square it clearly fails and it's by no means a critical test.
