Combination Square Buying Guide
Getting the right combination square for your projects is not as easy as it sounds. Even with the thousands of options available, falling for the wrong product is very easy. What then should you do to ensure that you get the right product?
We have put together some factors to consider when out shopping. We want to ensure that you get the right product and get value for your money. Take a look.
Durability
It would be best if you strived to get a durable combination square. However, this is dependent on several factors. First, look at the material used in the construction of the combination square. We advise that you settle on one made out of a combination of alloys.
Also, the blade needs to be made of stainless material to support outdoor usage. We suggest that you consider blades made of stainless steel as they never rust. You can use your combination square in the harshest of conditions without making constant purchase plans.
Size
You should consider the size of your combination square since it dictates how to use it. However, this is closely related to your intended purpose. What do you plan to do with your combination square? To be on the safer side, we advise that you settle on multiple sizes to fit a range of applications.
When working in your shop, you will realize that small to medium-sized squares come in handy for several jobs. Also, the size determines the portability of the tool. Therefore, if you’re working outside the workshop, you need a small or medium-sized combination square to move from place to place quickly.
Head
The head design plays a vital role in the overall functioning of the tool. Even though most combination squares come with similar heads, some have inside variations. We advise that you settle on a product that has a bubble level in the head.
The bubble level comes in handy in small projects, saving you time and effort as it does away with constantly switching tools in the building process. The interchangeability of the head also plays a vital role in the working of the device.
Even though all combination squares come with this feature, you may have difficulty getting the perfect fitting head design. We, therefore, advise that you make these heads available to you before making a purchase.
Budget
The combination square is a standard necessary tool offered by several manufacturers. You can be sure that the available products have different price tags. Therefore, create a budget based on what you need in a combination square.
Quality and durable tools usually are higher-priced. Therefore, expect to spend more if you aim to purchase a premium combination square. However, this does not mean that all low-priced or relatively affordable products are of poor quality.
We advise you to ensure that the price aligns with features such as the material of construction and functionality. Also, make your budget more flexible to include pricier options that you may have to consider.
All in all, ensure that the product you settle on gives you value for money.

Quality and durable tools usually are hiHow Do You Know If A Combination Square Is Accurate?
Accuracy with any measuring and leveling tool is vital, and there are ways to check accuracy. A combination square is accurate if the blade and ruler are parallel to each other.
To check for accuracy, place a straight edge on top of one end or side (depending on which way you want your measurement) with its long axis perpendicular against that surface. Then slide it across until both edges meet at an intersection point in the line where they cross over. If the two ends meet, then the combination square is accurate.
If the two points do not meet, you will need to adjust your blade and ruler until they are parallel with each other again before using them for any measurements or leveling work. If a combination square is inaccurate in this way (or if there’s an error on one end of its scale), that inaccuracy can be transferred when making cuts because those errors compound its lack of squareness.
What Are Combination Squares Used For?
Woodworkers use combination squares to ensure that their measurements are accurate and ensure they have a square surface. You can also use combination squares for leveling work; the blade is slid across an edge of your board until it meets with one end at 90 degrees (or as close to it).
The combination square then acts like any other straightedge when using its scale on top or bottom edges to measure distances from those two points. Combination squares may come equipped on either side by sliding blades, allowing them more versatility than just being able to slide along only long sides – this will enable woodworkers greater flexibility.
The long, versatile blade on a combination square makes it the perfect tool for ensuring that your joint is 90 degrees and checking to make sure you have an accurate 45-degree angle. The spirit level vial can be used as a depth finder or another way of measuring distance – don’t forget about its ruler function!
Why Buy A Combination Square?
The main advantage of the combination square is that it’s a multi-purpose tool. It can be used as an angle finder, depth gauge, and ruler, to name just three of its many functions!
Combination squares are made from either stainless steel or brass, which is durable enough for everyday use in the workshop. Most models have some form of rust resistance coating added by the manufacturer. Higher-priced. Therefore, expect to spend more if you aim to purchase a premium combination square. However, this does not mean that all low-priced or relatively affordable products are of poor quality.
We advise you to ensure that the price aligns with features such as the material of construction and functionality. Also, make your budget more flexible to include pricier options that you may have to consider.
All in all, ensure that the product you settle on gives you value for money.
