Product Description

Product Description

Starrett combination square consist of a machine-divided, hardened and tempered steel rule (or blade) on which is mounted an adjustable square head. A reversible lock bolt allows the blade to be turned over or end-for-end without removing the lock bolt or nut. This ensures true alignment of the blade and heads. Square head are made of cast iron and are not to be confused with the cheap imitation plastic or die cast heads on the market. The value of Starrett tools is that they are accurate and will last. As the name indicates, this tool can be used for many different purposes - a complete substitute for a whole set of common solid try squares, a 45 degree miter, a depth gauge, a height gauge, a marking or scribing gauge, a level, a plumb and, by withdrawing the blade, it can also be used as a precision rule. This saves littering the workbench with too many tools, each being necessary but may be used less. This results in the goal of all good craftsmen - better accuracy and greater efficiency.

From the Manufacturer

The 11H Combination Square series feature cast iron heads and machine divided, hardened, and tempered steel blades. Cast iron heads are not to be confused with the cheap imitation plastic or die cast heads on the market. The value of Starrett Tools is that they are accurate and will last.

I have been a furniture maker for 35 years. My life is about tools. Every time I pick up this square it puts a smile on my face. Generations of experience went into the details of this instrument, from the weight to the finish, to the engraving of the blade, It is simply perfect.
I have become frustrated with and have thrown away several Stanley and Empire squares. Insubstantial and inadequate. I will pass my Starrett on to my son. There are two sons though and only one square. This will be interesting.

I was apprehensive to spend the money I did on this square, but am I glad I did. It's the only one I've found that is anything near accurate enough to use for the most demanding projects. The C33 head is forged, this one is cast iron. Some reviewers were concerned about that and opted for the C33 head. I have to say though that the cast head on this one is solid. As long as you take care of your tools (and are careful not to drop it from a roof) this one should last. I was impressed enough with this one that I'm looking at a smaller one for my tool belt.

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
*Sturdy

Cons:
*None

Additional 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 stars

I do a lot of woodworking. Woodworking requires a high level of precision. I have tried other squares but unfortunately they are not precise enough for making cabinets, boxes, and other woodworking projects. Are Starrett squares expensive? They sure are in comparison to other squares. But when precision is a requirement then you are going to pay for it. When you are working with wood that goes as high as $8+ a foot, then spending a little extra cash to ensure that your equipment cuts straight, that your cabinets are square is well worth the money.

I'm a relative beginner to the woodworking world. I bought this because I wanted something more accurate than the $15 versions the big box stores sell. I also didn't want to plunk down the cash for a Starrett C33H-12-4R 12-Inch Combination Square with Square Head Only.

It arrived last week and I've got nothing but praise for this tool. It's dead square and has a very solid feel to it. The ruler is exceedingly precise. I'd need a magnifying glass to take full advantage of the 1/64" marks it's got. The ruler is also held by some sort of spring action to the base. This keeps things nice and square.

All in all, I'm very pleased with the tool and will probably be picking up a 6" version of this.

Starret is an American company who's products are top of the line. Except in this case. It is out of square by more than twice as much as the combination square this one was going to replace. The old one, a cheap $9.00 tool, is out of square by 1/64" over 12 inches. This brand new $71.00 Starret is out of squre by 1/32" over 8". The old one was spot on when it was new 15 years ago, but they wear over time just as this one did. I can't see spending nearly $100.00 for the Starret name only to receive a tool that cannot serve its purpose.

I did not check the ruler graduations for accuracy or precision. This tool is a square that isn't square so none of the other features is worth anything, either.

Amazon, as always, was quick to respond and the item is being returned for a refund.

Like others viewing this tool, I hated the idea of spending this much on a combination square to replace an old non-functioning square. I figured a combo square from the home center would be adequate, so I first purchased one there. It was out about 1/8" over the length of the blade, so i promptly returned it. This new Starrett square is absolutely dead square out of the box, and it includes a signiture of a Starrett employee putting his hame behind the quality. American made tool, by the way. Overall, it was difficult to spend this much on the tool, but it will indeed last for years and years providing perfectly square results. It really is worth the $$

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.
