Best Corner Clamps

When it comes to woodworking, it can be frustrating to hold two pieces of wood together at a 90-degree angle to join them. It’s a process that could benefit from an extra set of hands. A corner clamp, or right-angle clamp, is a better option for these projects.

A right-angle clamp consists of an L-shaped arbor that pushes against an L-shaped frame via a handle that attaches to a spindle. The vise holds two pieces of wood at a 90-degree angle with the ends perfectly aligned, which frees your hands to join the two pieces together either with glue or fasteners.

Do not make the mistake of thinking all corner clamps as same; otherwise, you might not get the most value out of your purchase. Remember, it is a versatile tool and will offer you a lot of utility as long as you have a clear idea of how it works.

If you are a beginner who wants to buy the best corner clamps in the market, then you came to the right place. In the following section of the article, we will give you a quick rundown of some of the top-rated units you can find to make your woodworking projects hassle-free.

Things to Consider when Buying the Best Corner Clamps

Now that you have gone through our list of reviews, here are a few things that you should consider when searching for the best corner clamps.


The most important aspect of a corner clamp is its accuracy. However, it is hard to check the accuracy perfectly without using it. But if you do not take this issue seriously and buy a faulty unit, you will not be able to get much use out of it. All your projects with it will be crooked and out of alignment.

One way to ensure you end up with an accurate unit is to slide the block to the machine’s outer walls. If it lines up perfectly, then you are good to go. However, if it does not, you are not getting a 90-degree corner clamp. But take this test a bit lightly since it does not guarantee the perfect accuracy even the clamp lines up.


Another critical aspect of the corner clamp is to check its jaw capacity. The capacity essentially dictates how big of a material you can use with the unit. In simpler terms, the distance between the clamping block and the outer wall is known as its jaw capacity.

Thankfully, manufacturers clearly state the capacity of the product in the product specifications. If you are planning to do heavy-duty projects with thicker and denser materials, you should go with at least 2.5 inches. However, most basic projects do not require that much capacity.


Lastly, it would help if you looked at the construction quality of the corner clamps. Make sure it comes with strong materials like die-cast aluminum or steel. Some low-budget units come with plastic bodies to lower the cost of the product.

However, they are not worth buying as they might break down within a few years.


Price isn’t the only factor that needs to be considered but sure is very essential when sampling out your best choice. A general rule of thumb is that the price needs to match the value of the product. To be sure, you can start by comparing your favorite picks online. However, you need to be careful since cheaper prices might sometimes mean a compromise on quality. For instance, our top pick – Kreg KHCCC 90° Corner Clamp – is of premium quality and goes for about $38 while the brittle IRWIN clamp will cost you $22, isn’t versatile and doesn’t last long.

Quality of Materials

Material quality is a fundamental factor that influences the versatility of a corner clamp. To evaluate a corner clamp’s durability and its capability to be used for a wide range of projects, we reviewed the quality of materials used to make it. This varied from plastic, metals, and sometimes both. For sturdy, durable, versatile, and lightweight clamps, most manufacturers often prefer to use heat-treated aluminum. Others such as the Miusuk right angle clamp are made of plastic and/or any other metal such as zinc. These are delicate and can only be used for light-duty projects. Finally, we also kept an eye on the paint used to coat the surface as it prevents corrosion. Note that subpar paints rub off on your workpieces.

If you need a bit more guidance before choosing one of the best right angle clamps, read on for answers to some of the most commonly asked questions.

How do you use a right angle clamp?

Place the clamp face-up on a flat surface, making sure there’s enough space for the two pieces you plan to join and that the clamp’s jaws are open. Slide the first piece into the clamp, lining the end up with the corner of the clamp’s arbor. Slide in the second piece until it meets with the first piece. Align the two parts until the ends are flush to each other with no overhanging edges. Hold the pieces in place with one hand while tightening the clamp with the other. Tighten by turning the handle clockwise until firm. Avoid over-tightening, which may damage the material.

How do you clamp an irregular shape?

Irregularly shaped materials will not fit flush to the clamp’s flat jaws, preventing it from adequately holding the piece. To fix this problem, you need to create a brace out of scrap wood that fits between the clamp jaws and the material. The brace, which can be a single piece or multiple pieces, includes a flat side that fits flush to the jaws and an irregular side that fits flush to the piece. The brace allows the clamp to grip firmly by filling the gaps between the jaws and the irregularly shaped piece.

How do you join two pieces of wood at right angles?

There are a couple of ways to do this. One method is to use a miter saw to create a miter joint. Cut each end to be joined at a 45-degree angle using a miter saw. Apply glue to the ends of the pieces. Using the right angle clamp, clamp the pieces so the mitered ends butt together, creating a mitered joint. Allow the glue to dry, then use nails or screws to reinforce the joint. If using screws, drill a pilot hole for each screw to prevent the wood from splitting.
