Essential Factors to Consider 90 Degree Corner Clamps for Woodworking

Knowing the most recommended right-angle clamps makes the choosing process a bit easier for you. Yet, if you are cognizant of the following essential factors to consider when choosing a suitable angle clamp, you can surely zero in on the best right-angle clamp for your needs:

Material

A right-angle clamp can give you tremendous clamping pressure if it is made of durable materials. Its construction, of course, is crucial to its performance. You can find, for example, clamps made of lightweight materials, meaning they are only suitable for light-duty clamping tasks like making a perfect picture frame. 

You will also find clamps made of sturdier and heavier materials. You can use these clamps for more challenging clamping projects like making cabinets or heavy welding materials. A good tip would be to look for clamps wrought in reinforced aluminum and steel arbors and spindles.

Capacity

Another factor to consider is the capacity of the clamp. The range and jaw’s width are two factors contributory to the capacity of the clamp. The majority of clamps come with jaws ranging from 3.5 to 4 inches and depth between 1 to 1.5 inches. 

If you want to clamp more surface area, you should go for a clamp with a deep and wide jaw. Remember that the greater the width of the jaw, the more consistent and stable your clamp would be. Besides, they can hold heavier and longer materials.

Spindle

Another factor to consider is the spindle of the clamp. The spindle is a long nut that gets connected to the handle. This handle threads through its arbor and down into bolt. You can turn the spindle using the handle. In turn, the clamp tightens as you turn the handle. As you see, the spindle is responsible for gripping the material in position. 

Spindles are made mostly of aluminum, and spindles that are heat-treated complement heavy-duty clamps. They also come with steel nuts. Thus, they offer better strength and durability than standard steel. These heat-treated spindles won’t bend or strip easily under pressure.

Accuracy

The material type and the accuracy of the clamp complement each other. So, if you want better clamping accuracy, you better go for durable clamps made of aluminum alloy and steel. These clamps won’t bend or warp under heavy pressure. 

Thus, you’ll get assured of getting a perfect right-angle connection when clamping. It will help if you also go for single-handle clamps because they often offer higher accuracy.

Clamping Range

A corner clamp is not good if it can’t hold its ground and keep materials supported. So, make sure that you will use a clamp that can hold the whole width of the materials. When selecting a clamp, you should check its jaws. The jaws should open wide and accommodate the width and thickness of your materials. 

On average, most clamps come with a width range of 2.36″ to 70.” The abovementioned clamps can join and handle two materials of different widths. 

Handle

The handle is another factor you should carefully consider when choosing a clamp. It is an integral aspect of a corner clamp. In many cases, however, you need to work out the handle using a single hand while using the other hand to steady the workpieces you’re clamping. 

So, it will help if you have a clamp that functions utilizing a single handle and allows for simultaneous clamping of both parts. Go for a handle that is large enough for tightening using one hand. 

Padding

Another factor is the padding. The handle should be easy and comfortable to grip; otherwise, you will have difficulty grasping it after prolonged use. Hence, it should come with non-slip paddings to ensure that you can easily hold the handles while you tighten the clamp. 

Setup

Many right-angle clamps necessitate aligning and turning using your two hands. Nevertheless, you can find clamps that allow for single-handle operation. The single handles operate an L-shaped jaw to clamp two pieces at once. 

These clamps also allow pivoting on its spindle and accommodate two pieces with different widths. Most angle clamps also come with holes in their bases. These holes let for easy mounting of the clamp to the workbench for better setup stability.
