Clamping two materials together at a 90-degree angle can be a very frustrating and time-consuming experience if you don’t have the right tools. Your finished project will never look right; in fact, it will look shoddy, and that is not good! Corner clamps make this task extremely simple, and so whether you are a hobby woodworker or a professional, they are a must-have for your toolkit. They are not just used to clamp the wood as some are multi-purpose and can be used on steel and holding bits in place while you work.

As with most tools, there are many choices, and the quality ranges from junk to decent! It can be very challenging knowing which corner clamp is the one you need, and so we have taken on the task of reviewing the market and seeing what’s available. From the hundreds of options (it’s taken us hours!), we have narrowed it down to our top 10 list.

We have selected our Best Overall and Best Value choices from that list and arranged them in an easy-to-read comparison table. At the bottom of the article, you will find our Buyers Guide packed full of hints and tips to help you with your selection.

Corner Clamps Buyers Guide

Picking the right tool for your projects is better than finding the device itself. To get the correct item, there are several considerations that you ought to look out for. Keep in mind that there are several corner clamps in the market and falling for the wrong one is not difficult. 

To find the right tool for your applications, here are some of the factors that you ought to look out for:


Quality is a wide factor of consideration that consists of several things. You should ask yourself whether your choice should be heavy-duty or not or whether it can be efficient when working alone. You also need to confirm whether you will need multiple clamps, among many other issues. 

Quality is also dependent on the type of material used. When it comes to corner clamps, you will choose between hard plastic or metals such as steel. However, we would advise you to settle on alloys, which are usually durable and reliable. The only setback when it comes to alloys comes in the cost. Corner clamps made of alloys are generally expensive. 

Plastic corner clamps are usually cheaper than their other counterparts. They are also lighter and highly portable. However, they are not as durable as those made from alloys or metals. They are primarily suited for light industrial work. 


It would be best if you stay safe while going about your projects. The best corner clamp should come with safety mechanisms to help you avoid unnecessary accidents. Therefore, ensure that your clamp of choice will not act weirdly during the whole application process. 

Some of the indications of an unsafe corner clamp include slipping, losing, and breaking. Apart from looking for suitable jaws, ensure that you also look out for the bolts, adjustment systems, and construction material. 

If you are wondering, the adjustment system allows users to manipulate the tightness of the tool, which can either be easy or complicated. When it comes to materials, consumers are not offered several options. Most corner clamps are either made of hard plastic or metals such as iron and, of course, alloys.

Your budget will determine the type of clamp that you will acquire. However, if you are an occasional user, you can borrow or invest in a low-priced one, provided that it can work and help you as you go about your projects. 

If you are a usual user who needs to have a clamp in the workshop, you should budget. You do not have to settle on an expensive option, but make sure that you do not end up with something average. Ensure that the clamp you decide on has all the qualities that you need in one. Ascertain that it has all the features required in one. 


How tightly do you want to clamp? Most people make a mistake by settling on corner clamps with the most potent clamping power when, in a real sense, they should consider the material they are working on. 

Wood and paper are relatively flexible, meaning that one needs a somewhat more robust clamp. However, when working on plastics and glass, you need medium clamps, so avoid breaking the board. Ensure that the jaws of your clamp do not slip. They should also be wide enough.

Lastly, you should confirm that your corner clamp is not crooked. You will need the right angle for projects such as welding, drilling, and trimming if you need the right outcome. Therefore, carefully scrutinize the angle of your clamp before purchase. You do not want to waste money on a faulty product. 


And so there you have it, our review and guide into the best corner clamps available today. Out of the ten that made it through our filter, we chose the Housolution Right Angle Clamp as our Best Overall pick. It’s super durable and versatile, so while it’s at the top end of budgets for this type of tool, the fact you can use it for more than just cabinet making adds a lot of value.

The WETOLS Angle Clamp is your best bet if you are on a budget. Again, it’s durable and versatile but loses points for being unreliable for some tasks. That being said, the price you will pay is an ideal first corner clamp to buy.
