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.

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 $$

This is a quality item, when you hold it in your hand you realize this is a precision piece of equipment. Numbers are easy to read and precise. Love the black wrikle finish. You won't be disappionted. It's a shame it so expensive, but quality in any product does not come cheap. Probley the last square I will need for years.

Don't know how one is supposed to write very much about such a simple tool, but here goes: I like it. Starrett makes good, solid, workmanlike tools, and you can't go wrong with one. Simple.

Very good product except for the fact that this model comes with a regular finish on the blade which is difficult for and old guy like me to read in the wood shop......so I exchanged it for model number C33H-12-4R which comes with a satin chrome finish which is much easier to read under artificial light. Having compared the two the 11H-12-4R is just as well made as C33H-12-4R.

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.
