10 Best Corner Clamps [2019]

Best Corner Clamp

Also called right angle or 90° clamps, corner clamps are ideal for holding woodwork or other items together at a 90° angle so that you can drill through or join them together using glue or screws.

Unlike using hammers, pliers and other similar tools, corner clamps are much more versatile and result in high-quality work because of their high precision in making right-angled joints.

However, these tools are available in different designs and sizes, which means you may have a difficult time picking one, especially if you don’t know what to look for. For that reason, this article covers 10 of the best corner clamps in detail for easy selection.

  • Body Material: Aluminum

With a 2.75-inch or 70mm jaw opening, MLCS’ 9001 has quite a wide jaw opening. This setup actually consists of clamps on both sides of the 90° corner and a movable jaw in the middle.

These bite into the object that you are working on firmly while a sliding T handle allows you to turn the fastening screw easily for high clamping pressure.

You also get two swivel points that enable the jaw to swing more towards one side so that you can work with two wooden blocks or metal pieces having different widths.

Other features include 2 oblong holes for easy mounting on a workbench and a sturdy aluminum body that is very durable. However, the built-in handle is not padded for comfortable use and the jaws don’t have V grooves for holding round objects.

How to Buy the Best Corner Clamp

How to Buy the Best Corner Clamp

1. Jaw Capacity

One of the most important things to check before buying a corner clamp is its jaw capacity/opening. Given in millimeter or inches, this value shows the maximum width of this opening, which then determines the maximum thickness of the object that you can fit in.

That said, the wider the jaw opening, the better. This is because you will not be limited to only work with small wood blocks or metal pieces. Ideally, 2.7 inches and above is good enough.

2. Material

Most of these right-angle clamps are made using aluminum but you may get certain variations that have zinc or other metal frames.

While all of these are strong enough to hold the entire working mechanisms on the clamp, aluminum has the advantage of being lightweight, which makes aluminum-made clamps easy to transport from one workstation to another.

Other things to look for include heat-treated frames, which are designed to be very sturdy, and surface coatings that prevent corrosion for long-lasting use.

3. Handle

There are two main types of handles to choose from for these clamps. A sliding T handle basically has a T design, and this lets you easily apply high torque so that the jaws can apply high clamping pressure for a good grip.

However, such handles lack soft padding for comfortable use.

On the other hand, soft rubber handles are very comfortable to use but they lack a T design for applying high clamping pressure.

Generally, rubber handles are better because even though they are not T shaped, this does not necessarily mean that you can’t tightly squeeze them so as to apply high torque and push the jaws firmly into the object being clamped.

4. Construction

In considering the construction of the clamp, there are two main designs that are available.

A swing jaw design is very compact and fits easily in tight spaces, but its swivel points introduce a lot of moving parts. This affects the overall strength and integrity of the clamp as a whole.

On the other hand, a double jaw design might be a bit large in size buts its rigid structure makes it stronger and more durable.

Both though are capable of clamping objects with different thicknesses and therefore, selection should be based on personal preference.

5. Weight

Lastly, for easy transportation between different workstations, a lightweight corner clamp is better because it will be easy to carry as you move to a different project in a different location.

However, ensure that this lightweight construction does not affect the strength and durability of the entire frame structure.

Conclusion

In summary, corner clamps are highly recommended because of their highly accurate 90° angles, which means you will be able to create perfect welds or wood joints for high-quality work.

However, you need to consider the jaw capacity as the main determining factor, with others such as handle, design, weight, etc. following suit.

All these are explained in detail above and after reading through, you will find it much easier to pick the best corner clamp that suits your needs.
