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.
This guide will review the top picks for some of the best right angle clamps for DIY projects.

What to Consider When Choosing a Right Angle Clamp
Joining wood, metal, or any other material at a right angle can be a clumsy process. A right-angle clamp can make the entire ordeal easier, but only if you buy the right one. To determine which right-angle clamp is best for your workshop, it’s prudent to consider factors like durability, accuracy, and clamping range.
Material
A right angle clamp’s construction is the key to its performance. Lightweight clamps are made out of thinner aluminum or even plastic, meaning they’ll work well for light-duty jobs, such as picture frame building, but they won’t hold up to clamping together heavier materials for projects like cabinet building or metal welding. For heavy-duty tasks, look for clamps with reinforced aluminum bodies and steel spindles and arbors.
Accuracy
Accuracy and material type go hand in hand. Durable aluminum alloy and steel clamps won’t warp or bend under pressure, which allows for a perfect 90-degree angle. Single-handle clamps also offer a high degree of accuracy, as they enable users to clamp both pieces simultaneously via a single handle once aligned.
Clamping Range
A right-angle clamp isn’t suitable if it can’t hold the materials you want to clamp together. Make sure to check how wide the clamp’s jaws can open to determine if it offers a wide enough range to hold the materials you need to join. Most clamps can hold materials up to 60 millimeters (2.36 inches) to 70 millimeters (2.75 inches) wide. All clamps on our list can join materials of two different widths.
Capacity
The clamp’s capacity incorporates both its range, described above, and the jaw’s width and depth. Most clamps have a jaw width between 3.5 and 4 inches and a jaw depth between 1 and 1.5 inches. A clamp with a wide and deep jaw has more surface area to clamp the materials being joined.
The greater the jaw’s width, the more stable the clamp can be holding longer and heavier materials in place. While a smaller angle clamp may suffice for a picture frame project, an angle clamp with a longer jaw is necessary for projects involving larger pieces, such as cabinetmaking.
Spindle
The spindle is the long nut attached to the handle that threads through the arbor and into a bolt. The handle turns the spindle, which tightens the clamp. Given that it’s responsible for holding the material in place, it’s the critical component in a right-angle clamp. Most spindles are made out of aluminum. Heavy-duty clamps feature heat-treated spindles with steel nuts, which are harder and thus more durable than standard steel. Heat-treated spindles are less likely to bend or strip under the pressure of clamping larger materials.
Handle
Given how tricky the process is to align two pieces of wood, metal, or glass into the clamp, the handle is an integral part of a right angle clamp. In most cases, users will want to operate the handle with one hand while using the other to steady the two pieces they’re clamping together. For ease of use, most right angle clamps work with a single handle that clamps both parts simultaneously. The handle should be large enough to tighten easily with one hand.
Padding
Getting a good grip on the handle as you’re holding everything in place is crucial. With that in mind, most handles feature padded nonslip grips that are easy to hold while tightening the clamp.
Setup
It used to be that right-angle clamps featured multiple handles and jaws that required more aligning and turning. Innovations in right-angle clamps make setup much more manageable nowadays. Clamps designed with single handles operate one L-shaped jaw that can clamp both pieces at the same time. These clamps can also pivot on the spindle to accommodate pieces with two different widths. And if that doesn’t offer enough ease, most angle clamps feature holes in the base that allow them to be mounted to a workbench to add more stability for setup.
FAQs
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.
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.
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’ll want 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.
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.
You can also join the two pieces using a basic butt joint. Simply place the end of one board against the side of the end of the other in the angle vice, making sure the ends are flush. As with a miter cut, use glue to join and reinforce with nails or screws once dry.
