Best Combination Square Reviews 2020

There are different types of combination squares with different parts, and each part is made of different materials that largely affect the price. A 12-inch combination square with a forged steel blade and satin chrome finish can cost about $120, while a less expensive option with fewer features can cost about $25.

We came across some cheap combination squares and realized that they were made with flimsy materials. You don’t want to trust the accuracy of the measurements you take with these as their calibrations cannot be trusted.

If you’re working on a precision-sensitive project, you know that being a single degree off can have a huge impact. A combination square can help you achieve exact measurements that ensure all your shelves are level and all your edges are square. Since you’re shopping for one, here are features to look out for:

• Accuracy
• Graduation style
• Calibration
• Scriber/ruler
• Construction
• Finish
• Measurement
• Blade
• Type of Level Vial

With these features in mind, let’s take a look at how each one affects this tool’s efficacy.

A combination square reduces the hassle of making accurate measurements, including angles and corners. Without using a chalk line or a long straightedge, you can use the scriber and ruler on the square to mark a long line with proper width. The square head can also be placed on your workstation and slid against the cutter to get your height measurement.
The graduation style increases the versatility of this tool because it contains different scales of measurement. It’s possible to switch graduation orientation by removing the blade from the head and reinserting it. Graduation styles range from 64ths to 8ths, depending on the set piece, and each one can be used for different purposes. For example, 4R graduation would be most suitable for woodwork as it has 8ths and 16ths on one side, and 32nds and 64ths on the other.

There are also different finish options for you to choose from. The standard finish is often of polished chrome. Some blades are thicker and stiffer than others, such as 3/32’’ blades, and their graduation marks are slightly darkener. You’ll also find squares with a satin chrome finish, which looks matte and may be easier on the eyes for some people because it reduces glare.

If you accurately set the blade of your combination square, you can use it to check the tenons and other important joinery on your project. With a dedicated marking gauge, you can strike parallel lines on the project you’re working on. The right-angle measurement and joining will result in straight wall corners, snug-fitting drawers, tight-closing windows, and quality craftsmanship! You can also scratch or scribe a line perfectly without smearing or smudging. The best combination square performs the composite tasks of marking gauge, try square, level, miter square, sawing square and much more.

Combination squares are so versatile, you can de-clutter your tool bag by emptying out your level, your square, your ruler and more. You can trust a good square to rip, miter, crosscut and make notches from those lines that you have carefully drawn. This tool is also flexible enough that it can be used for almost any type of project, from woodworking to making cards or scrapbooking.

Most combination square heads will allow you to slip the head in reverse format, rotate the lock bolt, roll over the blade and reinsert it in a fast and smooth process.

You can also make a short line seem long and parallel miter-gauge slots. When you move the square piece around, you can feel the gradient of the project for spots that need to be removed and holes that need to be smoothened out. The 45° anvil can be used for broad applications including decorative carpentry and picture framing.
