Best Combination Square For Woodworking

Introduction to Combination Squares

Combination squares are versatile tools popularly used in woodworking and metalworking. This multipurpose tool is typically composed of four main components: a ruler, a level, standard 45-degree miter markings, and an adjustable square head set at 90 degrees. Commonly used for checking measurements and ensuring accuracy of cuts, combination squares can also be used as depth gauges, protractors and other specialized jobs in carpentry and machining.

There are two main types of combination squares available on the market”standard models designed for general purpose use and premium quality squares made from high-grade materials such as stainless steel or hardened steel. Standard squares usually feature a ruler graduated in 16ths of an inch but can also come with different metric graduations for versatile use. Most also feature brass screws and calibrated heads to enable precise adjustment of the ruler against the square head.

Premium quality combination squares are ideal for professional woodworkers due to their superior build quality. These models tend to have greater durability, more accurate centering capabilities, higher accuracy scale readings, improved readability and overall more precise measurements. They’re also much easier to adjust compared to standard models, making them an excellent choice for woodworking tasks that involve precision measuring.



When choosing the best combination square for woodworking projects, consider your level of expertise. If you’re just starting out in woodworking crafts or if you’re working on simple projects such as furniture assembly or cutting simple joints like dados or rabbets, then a basic model will do just fine. However professional builders may want to opt for higher end models designed specifically for greater accuracy in measuring complex intersections or complex joinery techniques like dovetails or dowels joints etc. Consider how frequently the tool will be used, its intended purpose and price range before selecting the best fit from among the various available models on the market today.

Three Features to Consider When Choosing a Combination Square

1. Accuracy: When it comes to combination squares, accuracy is of utmost importance. Look for a model with markings that are easy to read and accuracy that is certified by the manufacturer. The scale should have increments as small as possible to ensure precise measurements.

2. Construction: Combination squares come in a variety of materials such as stainless steel, aluminum, plastic, and brass. Stainless steel is the most durable and reliable material, but aluminum and plastic may be sufficient depending on your needs. Choose a construction that will stand up to years of use and won’t rust over time.

3. Durability: Quality materials and construction are important for any tool, but when it comes to combination squares it’s especially important because the square must remain steady over long periods of time without wobbling or slipping out of position while you measure something accurately. Look for models that are built to last with hardened blades and non-slip grip surfaces on the handles or knobs.

What Makes a Quality Combination Square for Woodworking?

When looking for a combination square for woodworking it is important to find one that can accurately measure and make accurate marks. Quality combination squares should have measurements in both metric and imperial units, be well balanced and fit comfortably in the hand. The ruler should be made of high-grade metal or alloy, have micro-fine material underneath the head ensuring readings as close to zero as possible and also have clearly etched graduations which will not wear over time. The handles should be strong and comfortable to grip with a positive locking system that prevents unwanted movement. The blades should come with steel or cast iron heads, have adjustable depth stops which provide accurate depth settings across different materials, and be hardened and tempered to lengthen their life span. Finally, if the model has any additional features they should be professional grade such as extra strength scribed edges on the protractor head or variable pitch knurling on the screw that allow for finer adjustments during work.

How to Use A Combination Square To Measure Accurately



Using a combination square to measure accurately is not as difficult as it may seem. To begin, securely fasten the combination square to your workpiece with clamps or other appropriate tools. Adjust the combination square so the base is aligned parallel to your workpiece. Then, extend the blade out and ensure that it is smooth and level against your workpiece using the markings on the outside of the base. Once this is done, you can use either the calibrated edges of the blade or its cut-out protractor to measure angles, depths and lengths.. The combination square can also be flipped over for measuring longer levels or grids. Finally, adjust the locking screw to secure your measurement and voila — you have an accurate measure!

Maintenance Tips to Keep Your Combination Square Accurate

To help keep your combination square accurate, here are some tips on how to maintain it:

1. Periodically inspect the blade for flatness and make sure the edges are free of any nicks or burrs. It is especially important to check that the edge of the blade hasn’t been warped by using too much pressure when securing it into place.

2. Clean off any dirt or gunk from the blade and body with a damp cloth whenever necessary. This will ensure that there aren’t any particles obstructing it from making straight cuts and measuring accurately against surfaces.

3. Use light motor oil to lightly lubricate the moving parts to help them move smoother when sliding back and forth or turning through different angles of measurement.
4. Store your combination square in a dry place when not in use so that rust doesn’t form on the surface of the metal head and blade assembly over time due to exposure to moisture or humidity levels in your shop environment.

Final Thoughts

Choosing the right combination square for your woodworking projects can make all the difference to ensure precision and accuracy. Before purchasing a combination square, consider what kind of project you are working on and your budget. Quality matters when it comes to tools; higher-end brands tend to last longer while also providing improved features such as etched metal faces and adjustable settings. To get the most out of your investment, educate yourself on choosing between combination squares with metric or imperial measurements, consider if you need extra features like a protractor head or scriber, and how easy it is to read. Additionally, look for models that include accessories like machinists’ blocks, center heads, levels and columns ” these are useful if you are looking for more versatility from your investment into a combination square. Finally, always wear safety gear when woodworking and make sure that you understand how to operate the combination square correctly before starting any project.
