8 Best Corner Clamps – Reviewed in 2019:

1. Kreg KHCCC 90° Corner Clamp – Top Pick

Kreg KHCCC 90° Corner Clamp

The Kreg KHCCC 90° Corner Clamp is the one you’ll want to get if you’re looking for the best corner clamp on the market. This clamp is versatile enough to work on both 90-degree corners and T-joints, so you can use it to get the job done in a variety of situations. The one-inch capacity makes it a very versatile corner clamp that will work on a variety of different projects. Beyond its steel frame, it also has forged aluminum pads, which are lightweight, but also incredibly strong and durable.

We also really like the cutout in the pads, which allows you to put pocket screws in place without undoing the clamp. This saves you a lot of time.

The one thing that could be better is the cumbersome adjustment. Some wood sizes require a lot of adjustment to get the clamp on tightly, which doesn’t always feel like a good use of your time. Still, if you’re looking for a corner clamp with versatility and the kind of attention to detail that makes a project easier, get this one.

Pros
  • Works on 90-degree corners and T-joints
  • One-inch maximum capacity
  • Aluminum pads
  • Cutout for pocket screws
Cons
  • Cumbersome adjustment

2. Wolfcraft 3415405 Right Angle 90 Degree Corner Clamp – The Runner-Up

Wolfcraft 3415405 Right Angle 90 Degree Corner Clamp

The wolfcraft 3415405 Right Angle 90 Degree Corner Clamp is another great clamp. One of the best things about it is that it doesn’t take a lot of setup. Put the boards in place, tighten the screws, and you’ll be good to go. The jaws have a massive, 2.5-inch capacity, so you’ll be able to do just about any kind of project you can think of with this clamp. The large capacity makes it good for some custom solutions, like extra-wide picture frames. This clamp also comes with a five-year warranty, so you know the manufacturer is willing to stand behind the product.

This model has a quick-release mechanism, which is both a nice feature and its Achilles heel. It lets you remove the clamp quickly, saving a lot of time, but the mechanism used to tighten it depends on that part. If it ever fails or strips, it will be very difficult to tighten the clamp. Overall, this is a great tool, and if the quick-release mechanism was more consistent, we could easily rank it first. Even with that flaw, it’s still something many people will like.

Pros
  • Minimal adjustment required
  • 5-inch capacity
  • Five-year warranty
  • Quick-release mechanism
Cons
  • Quick-release sometimes fails

3. HORUSDY 90° Right Angle Clamps/Corner Clamp – Best for the Money

HORUSDY 90° Right Angle Clamps/Corner Clamp

The HORUSDY 90° Right Angle Clamps/Corner Clamp is very much like the previous one on our list. It features a similar, easy-to-use design. Just put the wood in place and turn the screw to tighten. That means very fast operation and limits the amount of time you’ll have to spend setting things up. Like the previous clamp, it has a 2.5-inch capacity, which means you’ll be able to clamp almost anything at 90 degrees with it. It also has a quick-release mechanism, so you won’t have to unscrew it tediously when you’re done.

This clamp beats the previous one in one key area: price. You can get it for about 60 percent of what you’d pay for our second-place choice. That price is low enough to earn this clamp the title of best value for the money here. However, the quick-release sometimes fails, and that makes it hard to tighten the clamp. If that problem were resolved, we could see this model rising to the top spot on our list. Even so, it’s still a good value buy.

Pros
  • Easy adjustment
  • 5-inch capacity
  • Quick-release mechanism
  • Great price
Cons
  • Quick-release sometimes fails

4. Can-Do Clamp – Best for Picture Frames

Can-Do Clamp

The Can-Do Clamp does a lot well, but it’s designed in a way that makes it the best picture frame clamp on our list. Since it uses one part to hold both pieces of wood in place, you can be assured that both are aligned correctly, especially when they’re of the same thickness, which is typically the case when you’re making a picture frame. It can be mounted to a workbench, so if you’re looking for a semi-permanent solution, this corner clamp will meet your specifications. It’s also made from aluminum, so it’s both lightweight and very strong, which is something you always want in your tools.

This clamp features a T-handle for adjustment. This lets you put extra power in your turning to ensure that you get a good grip on the pieces you’re going to be joining. The one thing that hurts this model is that it sometimes leaves red marks on the wood, which is a sign that the paint used is subpar. If you want a mountable corner clamp that excels with picture frames, you’ll be hard-pressed to find something better.

Pros
  • Can be mounted to a workbench
  • Great for picture frames
  • Aluminum frame
  • T-handle for adjustment
Cons
  • Sometimes marks wood

5. Milescraft 4005 90° CornerClamp

Milescraft 4005 90° CornerClamp

The Milescraft 4005 90° CornerClamp is most similar to the top choice on our list, with a few significant differences. It has a 1.25-inch capacity, which makes it just a bit larger in that category than the top model. The swivel head design makes it easier to get it set before you clamp down. It’s also far lower-priced than similar clamps, and it’s price-competitive with some other designs on our list. The downside to that is that it’s made from unknown metal, which means it’s something of a gamble when it comes to long-term strength and durability.

Unfortunately, there’s no pocket screw notch, so you’ll have to wait until the glue dries to add a pocket screw if this clamp covers the spot. The design also makes it tricky to use if your primary goal is to make picture frames. Ultimately, it’s going to have to be awkwardly vertically stacked to make that happen, and it’s probably not going to work well enough in that area to be worth buying. However, it has other uses, and for the price, it’s not a terrible buy.

Pros
  • 25-inch capacity
  • Not expensive
  • Swivel head design
Cons
  • No pocket screw notch
  • Tricky for picture frames

6. Housolution Right Angle Clamp

Housolution Right Angle Clamp

The Housolution Right Angle Clamp is reminiscent of the fourth-place model on our list. It uses a similar mechanism where it tightens both pieces into place at the same time with a single, centrally located part. That makes it great for picture frames, since it will be easy to align two pieces of the same size with this device. It can be mounted to a workbench, so if you want a permanent or semi-permanent solution, this is the one for you. Plus, this clamp is made from aluminum, which means you get a low-priced, lightweight tool, but can still expect it to be strong and durable.

This clamp doesn’t come with a T-handle. If you’re going to be using the clamp over a bench, you may like this one’s handle better. Otherwise, you may miss the extra tightening power that comes from a T-handle. What ultimately sinks this otherwise great tool is that it costs a lot. It’s one of the most expensive clamps, and yet it doesn’t provide many superior features. Overall, this is a decent option, and if it were sold at a lower price, more people would be satisfied with it.

Pros
  • Can be mounted to a workbench
  • Great for picture frames
  • Aluminum frame
Cons
  • No T-handle
  • Expensive

7. ODELENWA Right Angle Clamp/Corner Clamp

ODELENWA Right Angle Clamp/Corner Clamp

The ODELENWA Right Angle Clamp/Corner Clamp fits in the mold of a few others on our list. It comes with the single center mechanism designed to tighten both pieces of wood at the same time. However, the best thing about it may be its price. It’s one of the least expensive corner clamps on our list, and that says a lot. Like similar clamps, it’s bench-mountable, so you can secure it to your workbench for frequent use or superior clamping. Plus, it’s made from aluminum, so you can expect it to be lightweight and last a long time.

However, ODELENWA isn’t the easiest company to contact. If you do have a problem with your tool, you may not be able to get it resolved outside of returning it. Something else to note about this model is that it has a slightly smaller clamping range than others with similar designs. If you need a clamp that can work with extra-large pieces, this isn’t it. While some people can be happy with this one for the price, there are lots of ways it might go wrong.

Pros
  • Inexpensive
  • Aluminum body
  • Bench-mountable
Cons
  • Tricky customer service
  • Slightly smaller range

8. Pro-Grade 59162 Corner Clamp

Pro-Grade 59162 Corner Clamp

The Pro-Grade 59162 Corner Clamp is designed in a way that will make people wonder about the accuracy of its name. It has a lightweight, yet sturdy, aluminum frame that should provide good durability, at least in theory. It also has a wide, three-inch jaw range, which makes it superior in that category to many clamps on our list. However, this corner clamp has one serious flaw, which is that many units ship with deflection problems. This is a tool designed to make great 90-degree angles, so if it can’t do that, you have problems. That’s a huge red flag that hurts this model’s value.

It also doesn’t have the best durability. Many users report at least one part that broke, but what breaks tends to vary from unit to unit. That suggests that this clamp is cheaply made. Worse, it struggles to get a grip on thinner materials, which makes it a poor choice for use on picture frames. There’s not a ton to like about it, so if you’re looking for a great corner clamp, you’d be wise to look elsewhere.

Pros
  • Aluminum frame
  • Wide range
Cons
  • Deflection issues
  • Poor durability
  • Struggles with thinner material

Conclusion

The Kreg KHCCC 90° Corner Clamp is our favorite due to its aluminum pads, cutout for pocket-hole screws, and compatibility with 90-degree corners and T-joints. The wolfcraft 3415405 Right Angle 90 Degree Corner Clamp has a large capacity, a five-year warranty, and a quick-release mechanism, but the latter’s inconsistency keeps it out of first. In third, the HORUSDY 90° Right Angle Clamps/Corner Clamp is easy to adjust, and has a large capacity and a quick release. Since you can get it for about half of what you’d shell out for the top options on our list, it’s the best value buy here.

The Can-Do Clamp takes fourth place with its aluminum frame, T-handle, and its ability to be mounted. Its occasional wood marks keep it out of the top three. Next is the Milescraft 4005 90° CornerClamp, which comes with a 1.25-inch capacity, a low price, and a swivel head design. However, it lacks a pocket screw notch and can be tricky for picture frames. The Housolution Right Angle Clamp can be mounted to a workbench and is great for picture frames, but it lacks a T-handle and boasts an unjustified high price.

In seventh, the ODELENWA Right Angle Clamp/Corner Clamp is inexpensive, has an aluminum body, and is bench-mountable. Its tricky customer service and slightly smaller range hurt its value. Last place belongs to the Pro-Grade 59162 Corner Clamp. It has an aluminum frame and wide range, but deflection issues, poor durability, and struggles with thinner material make it a bad overall buy.

Hopefully, we’ve helped you better understand the world of corner clamps, and have led you to the one that will make your next project a breeze.
