I love this thing so much that I bought it again

Reviewed in the United States on May 20, 2024

Size: 16-inchStyle: Regular Combination SquareVerified Purchase

I had the 12-inch version of this product and found myself using it for more than just woodworking. I used it for projects all around the house and it was probably my most used measuring tool.

I misplaced it for a few days and went nuts. Decided there were some instances where I wanted it to be just a bit longer and got the 16-inch version.

Found the 12-inch one a few days after getting the 16-inch version, and I did not feel at all compelled to return the 16-inch one.

Its simple, not bulky, handles well in different directions. Has a scoring pin, a level, and an adjustable ruler. Does what it needs to and does it well.

IRWIN 6" SQUARE #1794469 - AFFORDABLE QUALITY AND ACCURACY

Reviewed in the United States on March 26, 2017

Size: 6-inchStyle: Regular Combination SquareVerified Purchase

I just got this Irwin square today, and at this price point im very pleased. Nice heavy build quality along with touches like a brass lock nut, brass knobbed scribe that is firmly held in the casting by a friction sleeve and even a brass level plug really add to the build quality and heavy duty feel of the casting which is itself nicely done and doesn't look cheap -- I also have a comparable Stanley and I like this one better, the casting is heavier and thicker at the machined edges like a Starrett and feels like a bit better quality than the Stanley. The Irwins rule is nice and thick, easy to read and made of stainless steel not clear coated metal that will peel and rust as my Stanley has, but I have no use for the mm scale on the Irwin, I think they should make either one or the other and not force metric on you if you don't need it -- I don't know a single carpenter at least here in the US that works with mm. The casting borders are nice and thick on the machined sides, giving the look of maybe a Starrett or similar - However a Starrett is around $100+ and the casting on it is iron, which isn't as soft as the Irwins aluminum or zinc whatever it is - but the Irwins cost is MUCH lower and Starrett quality is legendary & in a different class - but you pay dearly for it and most of us cant afford that kind of luxury for it to be lost or stolen on a job sight. I checked my example for squareness soon as I got it as I saw a reviewer who said his was not, fortunately mine is right on so buyers should always check, indeed any tool that involves accuracy should be checked and verified. I did spend some time gently cleaning up the casting and rules corners and edges with a stone, lightly oiled the threads and moving parts and now it slides much smoother than when I first got it - it wasn't bad mind you just needed a bit of "optimizing" to make it good as it could be - Im very pleased and also glad I bought the 12" version as well elsewhere, what ive said in this review also applies to the 12" version and im very pleased with both examples. Empire makes one of similar quality and a stated accuracy within .002 of an inch and price is comparable but the Irwin wins out with a bit more brass bling, for example the level plug is plastic on the empire and brass on the Irwin, and the blue Irwin casting is an eye catcher if that's of any value. Oddly the Irwin makes no specific claims regarding accuracy on their packaging, but they should as it seems to exude enough quality to back it, at least my example does. Im even tempted to purchase the 16" version as these are such a good value. If I had any criticisms, it would be to be careful about dinging the softer aluminum casting on the machined corners,as this would cause out of square measurements, but it is a precision measuring tool and should be treated as such, but thats not always reality on a job site, and no square in this price range im aware of has an iron casting so im not saying the Irwin is at fault since all castings in this price ranges are made of similar material just stating fact, aluminum would be easier to ding than iron, but price is related to material cost so I still say for the price this square is a bargain and I don't see how you could find one any better for the price. Final word, there are many very good reviews for this square and that speaks for itself, you cant go wrong for the money its a really nice tool.

Maybe the best value 6" combo square

Reviewed in the United States on March 30, 2020

Size: 6-inchStyle: Regular Combination SquareVerified Purchase

This is my best 6" combo square. The slide is very flat and very easy to read, so long as you want to use imperial. The brass nut has a nice and sharp knurling and feels great.

Cons: The rule was uniform in width end-to-end, but it had just a wee bit of a banana such that the straight edge is not actually straight and the angle of the rule would change when you move it.

Also, the reference faces of the body are hollowground, and only 4 tiny points make contact with the work. Well, only 2 of those four would make contact when doing one of the most common things you would use these for. And when measuring an outside corner, it would obviously read slightly acute, due to the slight hollowgrind. But it looks like many if not all of these cheap combo squares are made this way.

All that said, I wouldn't go adjusting the square like you see on YT until you sort these two points out. There's no way to get repeatable results to even know it's off, out of the box. And it will change, anyway, if and when you decide to fix these two things.

Gritty movement: I found the ruler movement was very catchy and rough, despite deburring. I finally figured out the reason. The hook barely engages the slot, so the hook rubs against a very tiny bit of steel on the corner of the slot in the ruler. I was able to jam a shim behind the draw bolt so that it would engage more fully. This cured it.

Metric:
Some squares, you can flip the slide for metric.
This slide works in inches in one direction. And if you flip the slide, you can read in inches on the left and metric when you flip the square to look at the other side. This is how I use it, and it is great, unless you are hardcore metric.

Excellent as expected

Reviewed in the United States on May 14, 2024

Size: 16-inchStyle: Regular Combination SquareVerified Purchase

I have the smaller 6" version, that really only measures up to 4.75" or so due to the locking mechanism not being able to grab anything past 4.75"... So I had to upgrade to this bigger one. This might become my new go-to square! Solid construction, tight tolerances. The only con might be the edges are slightly sharp. I haven't gotten cut yet but we'll see...

I've been searching for a high-quality combination square made in the USA here in India for a while now, and the Lenox Tools Irwin Tools Combination Square on Amazon exceeded my expectations. Not only is the tool well-built with clear, precise markings for accurate measurements, but the seller's timely delivery was impressive. Overall, I highly recommend both the product and the seller for anyone in need of reliable tools and exceptional service.

You only had one job...

Reviewed in Germany on October 16, 2022

Size: 6-inchStyle: Regular Combination SquareVerified Purchase

I used the true square test by drawing a line perpendicular to the base of the ruler on a manufactured edge of my table on both sides of my ruler (flipped) along total 6 in. The superimposed lines had about 1 mm difference at the end of the line proximal to base of the ruler. I was able to make a square with a laser printer with a true 90 deg angles using same test. Only good for small projects.

Edit:
There's some wiggle room on the screw lock and track on the ruler, just press the ruler against the locking mechanism and it's actually truly square so very trustworthy!
