Rabbet Plane vs. Shoulder Plane: How to Use Each for Better Joinery

Hand planes aren't just for flattening boards and smoothing wood surfaces. Some of the most useful hand planes in a woodworking shop are designed specifically for cutting and fine-tuning joinery.

Two of my favorites are the rabbet plane and the shoulder plane. At first glance, these specialty hand planes look similar. Both have cutting blades that extend all the way to the sides of the plane body, allowing them to work right into the corners of a joint.

But they serve different purposes.

A rabbet plane is designed to cut accurately sized rabbets along the edge of a board. A shoulder plane excels at refining existing joinery, especially fitting tenons and cleaning up shoulders.

Understanding the differences between these tools — and knowing when to reach for each one — can make a noticeable improvement in the accuracy of your woodworking joints.

What Is a Joinery Plane?

Most woodworkers are familiar with bench planes. These are the traditional hand planes used to flatten, straighten, and smooth wood surfaces.

Joinery planes are a little different.

Rather than working across broad surfaces, they're designed to cut or refine specific features of woodworking joints.

For example, a table saw can quickly cut the cheeks of a tenon, but getting the tenon to fit perfectly in its mortise may require removing just a few thousandths of an inch.

That's where a specialty hand plane comes in.

With a sharp blade and a light cut, you can remove a thin shaving, check the fit, and repeat until the joint slides together exactly the way you want.

Joinery planes are especially useful when you combine traditional hand-tool techniques with modern power tools.

How a Rabbet Plane Works

A rabbet plane is designed to cut a rectangular recess along the edge of a workpiece.

What makes it different from a standard bench plane is the width of the cutting blade.

On a bench plane, the blade is narrower than the body. This leaves a small portion of the sole on either side of the cutting edge.

On a rabbet plane, the blade extends all the way to the sides of the body. This allows the cutter to reach into the inside corner of a rabbet without leaving a narrow strip of uncut material.

But that's only one of the features that makes a dedicated rabbet plane useful.

The Depth Stop Controls Rabbet Depth

A depth stop is an adjustable attachment that limits how deep the plane can cut.

Before cutting a rabbet, set the stop to the desired depth. As you make successive passes, the cutter removes material until the stop contacts the workpiece.

At that point, the plane stops cutting deeper.

This makes it easy to produce rabbets of consistent depth on multiple parts.

The Fence Controls Rabbet Width

A dedicated rabbet plane also has an adjustable fence.

The fence slides along two rods and determines how much of the blade is exposed beyond the workpiece edge.

By adjusting the fence, you control the width of the rabbet.

During the cut, the fence rides against the face of the board, keeping the plane aligned and the rabbet square.

Together, the fence and depth stop allow you to cut accurately sized rabbets without repeatedly measuring the workpiece.

A Scoring Blade Helps Prevent Tearout

Another useful feature of many dedicated rabbet planes is a small scoring blade, sometimes called a nicker.

This cutter sits just ahead of the main blade and scores the wood fibers along the edge of the rabbet.

It's particularly useful when cutting across the grain.

Without a scoring blade, the main cutter can lift and tear the wood fibers beyond the edge of the cut.

By severing those fibers first, the nicker helps produce a cleaner shoulder.

Some rabbet planes also feature a skewed main blade, which produces a slicing action that can make cross-grain cuts easier.

How to Cut a Rabbet with a Hand Plane

Cutting a rabbet with a dedicated hand plane is straightforward once the fence and depth stop are adjusted.

Start by securing the workpiece in a vise. I like to use a tail vise that holds the board at both ends.

One important detail is to position the workpiece so the edge being planed extends slightly beyond the workbench.

This ensures the plane's fence rides against the workpiece rather than accidentally referencing the edge of the bench.

Step 1: Set the Fence and Depth Stop

Adjust the fence to establish the desired rabbet width.

Then set the depth stop to control how deep the cutter will go.

Make sure both adjustments are secure before beginning.

Step 2: Keep the Fence Against the Workpiece

As you push the plane, use your fingers to maintain firm contact between the fence and the face of the board.

This helps keep the rabbet square and prevents the plane from drifting away from the workpiece.

Step 3: Start with Short Strokes

Rather than beginning with full-length passes, start with short strokes at the far end of the board.

After several passes, move your starting point farther back.

Continue lengthening the strokes as the rabbet develops.

This technique helps establish the cut and keeps the plane tracking accurately.

Step 4: Plane to the Depth Stop

Once the rabbet is established, continue with longer passes until the depth stop contacts the wood.

The result is a clean, consistently sized rabbet.

WOODSMITH TIP: Fine-Tune Machine-Cut Rabbets. You don't have to cut a rabbet entirely by hand to benefit from a rabbet plane.I often cut most of a rabbet at the table saw, leaving it slightly undersized. Then I use the rabbet plane to remove the final shavings and bring the joint to a precise fit.It's a great example of how hand tools and power tools can work together.

What Makes a Shoulder Plane Different?

A shoulder plane shares one important feature with a rabbet plane: The cutting blade extends to the sides of the plane body.

This allows the shoulder plane to work right into the inside corners of a joint.

However, there are some important differences.

Unlike a dedicated rabbet plane, a shoulder plane typically doesn't have an adjustable fence or a scoring blade.

Instead, it relies on existing surfaces of the workpiece to guide the cut.

The blade is also positioned at a much lower angle than the cutter in many traditional rabbet planes.

That low-angle design makes the shoulder plane particularly useful for trimming end grain, such as the shoulders of a tenon.

The result is a tool designed more for precision fitting than for removing large amounts of material.

How to Use a Shoulder Plane to Fine-Tune Joinery

One of the best uses for a shoulder plane is refining joinery that's already been cut with a table saw, router, or hand saw.

Because the cutter reaches the sides of the plane, it can remove material right up to the shoulder of a joint.

For example, you can lay a shoulder plane on its side and use it to widen an existing rabbet slightly.

You can also use it to clean up corners or remove small irregularities that prevent two parts from fitting together properly.

But where a shoulder plane really shines is in fitting mortise-and-tenon joints.

Fitting Tenons with a Shoulder Plane

A mortise-and-tenon joint needs two things to fit properly.

First, the tenon must be the correct thickness to fit the mortise.

Second, the shoulders must be clean and square so they seat tightly against the mating workpiece.

A shoulder plane can help with both.

Remove Dado Blade Marks from Tenon Cheeks

When you cut tenons using a dado blade at the table saw, the surface of the tenon cheeks may have small ridges.

These marks usually don't prevent the joint from working, but they can make fine-tuning the fit more difficult.

I like to leave the tenons just a little thicker than necessary when cutting them at the table saw.

Then I use a shoulder plane to remove the ridges and gradually reduce the thickness of the tenon.

Take a light shaving from one cheek, then check the fit in the mortise.

Repeat as necessary until the tenon fits snugly without requiring excessive force.

The goal is a joint that fits securely while still allowing room for glue during assembly.

Trim Tenon Shoulders for a Gap-Free Joint

Another common issue with machine-cut tenons is a small step where the shoulder cuts meet.

Even with a carefully adjusted table saw, these slight irregularities can appear.

They may not affect the strength of the joint, but they can prevent the shoulders from seating tightly against the mating piece.

A shoulder plane is ideal for correcting the problem.

Position the plane so its sole references the tenon cheek and the cutting edge trims the shoulder.

Then take a few light passes to remove the high spots.

Because the blade reaches the side of the plane, you can trim right into the inside corner.

The result is a clean shoulder that seats tightly against the workpiece for a crisp, gap-free joint line.

WOODSMITH TIP: Sneak Up on the Fit. When fitting a tenon, it's better to remove too little material than too much. Take light passes and test the joint frequently. You can always remove another shaving, but you can't put the wood back once it's gone.

Which Joinery Plane Should You Buy First?

If you're considering adding a specialty hand plane to your workshop, the best choice depends on the type of woodworking you do.

If you regularly cut rabbets by hand, a dedicated rabbet plane with a fence and depth stop is a useful addition.

It provides the control needed to create accurately sized rabbets, and the scoring blade makes cross-grain work more manageable.

On the other hand, if you do most of your joinery with a table saw or router, a shoulder plane may be the more useful first purchase.

It's particularly handy for fitting tenons, trimming shoulders, and making the small adjustments that can turn a good joint into a great one.

You don't need to abandon power tools to enjoy using specialty hand planes.

In fact, combining the two approaches is often the best way to work.

Better Joinery Starts with Better Control

Rabbet planes and shoulder planes aren't the first tools most woodworkers think of when they hear the words hand plane.

But they can be some of the most satisfying tools to use.

A rabbet plane makes it possible to cut clean, consistent rabbets with a few simple adjustments. A shoulder plane gives you the precision to fine-tune tenons, clean up shoulders, and bring machine-cut joints to a perfect fit.

And there's something rewarding about making those final adjustments with a sharp hand plane.

Sometimes all it takes is one or two thin shavings to make a joint fit exactly the way it should.
