Starrett Steel Combination Square with Square Head - 12" Blade Length, Cast Iron Heads, Reversible Lock Bolt, Scriber, Spirit Level, 4R Graduation Type - 11H-12-4R

I was using an empire combination square that just would not stay square (about 1/16" off at 12"). I finally bit the bullet and spent the money on the Starrett after seeing nothing but positive raves about their quality and accuracy. I am not disappointed! This square is perfectly square out of the box and feels very sturdy in my hands. The marks go all the way down to 64ths, but my old eyes are having a hard time seeing that small so I stick with 32nds. Great product. If you are on the fence about it, do it, it's worth the expense if you need accuracy.

Amazing reliability and great American craftsman. Been using for a few years now. No rust whatsoever

First, I get it. This square is really expensive. But before I purchased this, I had no idea how my woodworking was being compromised by having tools that were set up using a square that I *thought* was 90 degrees, or close enough (so I thought). From tablesaw set up, to miter gauge set up, to jointer set up, to dovetail jig set up, to checking cases for square - everything. The errors introduced by my cheaper, inaccurate squares made *everything* more difficult. And the errors compound themselves as work proceeds. Knowing that I now have a square that is consistently, and truly accurate has changed my work considerably. I've had to re-tune all my woodworking tools. I saw videos on-line regarding combinate square shootouts and how to tune-up an insufficiently calibrated square, but I didn't want to go down that path. If all you do is rough carpentry or nothing requires precision, you don't need this square. But if you're a woodworker, bite the bullet, close your eyes, take a deep breath, and spend the money on this square.

This combination square is great. I am all about saving money on tools any time I can. Gauges and measuring equipment though are one of those areas where the money spent is worth it for a lifetime. This square is right on point and I can count on it for precision 45 degree and 90 degree checks and marks. I am glad I went with the starret model. It costs more but is worth it in the long run. The faces were machined perfectly flat on the square I received and all of the degree measurements check out on several accurate protractors. It feels solid while being used and the ruler doe not move at all when the nut is tightened. I could not ask for more from a combo square.Dimensions can be seen in the photos I have attached. One side has 1/32" graduations.Included in the box will be a certification from the factory.Pros:*Very precise*Well built*SturdyCons:*NoneAdditional Considerations:When it comes to gauges. Spend the money. Its worth it in the long run.Overall: 5/5 stars (>=.5 rounds up, <.5 rounds down) => 5 starsIf you have any further questions regarding the product in my review please leave a comment below and I will get back to you as soon as possible.

It’s amazing how much better your project can be when your measuring tools are dead on.

It's a Starrett... when it comes to precision marking and measuring tools NO ONE does it better. My 6 inch combination square is from another manufacturer. I bought it at a big box home center. It is accurate and it works OK but it doesn't compare to this 12 inch Starrett. The Starrett is heavier which gives it a great feel when you are working with it. The Starrett has great adjusting components too. A slight twist of the knob with my thumb and the rule is locked in place. No wiggles. No wobbles. To get that performance from the home center brand I have to really crank down with my thumb and index finger. The method used for marking the graduations also make this a superior tool. Starrett uses laser engraving. Not so with a less expensive brand. That means your graduations will (eventually) wear off. My cheapy 6 inch is already showing signs of wear after two years. The Starrett looks the same as when I took it out of the box-and I use it A LOT more. Over your lifetime you can by one Starrett or several of the home center brand. Oh... did I mention it's made in the USA?

If you all you work with is 2x material and plywood, then pick up a speed square at your local hardware store...if you want to build quality furniture or heirloom pieces, then this is what you want.If all you have ever held were the combination squares that you can find on the rack at your local hardware store, then you are in for a treat if you are able to wrap your fingers around a Starrett. First thing you will notice is the weight, not only is the cast Iron head heftier than the cheap aluminum or zinc in the typical 10 dollar square, the blade is heftier as well. The fit and finish are top notch, from the hardened awl to the etching on the blade. The most important thing however is that you know that this will be 100% accurate and square to 90`. (you can easily google how to check your square for square, i.e. 2 parallel line test) and it will stay that way. Also, made in the USA.My only wish was that I got the hardened steel head instead of the cast iron (I have a 6 inch square with the steel head) as it has better rust resistance. Also, make sure you get the satin blade, not the polished, much easier to read...this one has the satin blade.

You feel the quality the minute you hold it in your hand.
