A jointer is a woodworking machine that smooths and flattens the face and edge of stock lumber to make it perfectly square. Instead of running a tool against wood like one would do using a hand planer, with a jointer, the wood is pushed against the tool.
A jointer consists of a long flat surface bisected by a cutting head with a cast-iron guide fence. As the wood runs through the jointer, the cutting head’s blades remove a layer of the wood’s surface to create a perfect square. If you’re in the market for a jointer, keep reading to learn what factors you should consider when shopping for one of these powerful tools.

What to Consider When Choosing the Best Jointer
Various factors should come into consideration when you shop for a jointer, including power, blade width, table length, and portability.
You’ll typically have two different types of jointers to choose from: a larger, stationary cabinet-style unit and a smaller, mounted benchtop unit.
A benchtop jointer makes a popular choice for home woodworkers who don’t need the industrial strength of the larger and more expensive cabinet-style jointers. Smaller and lighter, they lack the power of a cabinet-style jointer, but they offer easy storage and portability.
Whether you choose a benchtop or a cabinet-style model, the best jointers should include sturdy adjustable fences and metal guards that allow for precision cutting. Cabinet jointers will include more substantial fences than those on a benchtop jointer, since cabinet jointers handle longer pieces of wood.
Power determines how easily a jointer cuts through wood. A more powerful jointer generally leaves a smoother finish on the wood than a less powerful model. High-powered models also do a better job of cutting through hardwoods and handling broader cuts.
A 6-inch jointer typically has a 1-horsepower motor—sufficient to handle most softwoods, hardwoods, and even many exotic woods. Jointers with 8-inch blades require motors with 2-horsepower engines. High-end commercial-grade jointers with blades up to 16 inches wide feature motors with as much as 3 horsepower.
Of course, build quality matters with most power tools, and it may matter most in a jointer. These tools make wood stock perfectly smooth and square, which requires the tool to be built from quality material that won’t bend or sag. Look for jointers with sturdy cast-iron feeder tables and guide fences that will stand up to long-term use.
Blades and Cutting Depth
Cutting depth determines how many times the user will have to run the wood through the jointer to make the wood smooth and flat. Cutting blade widths vary from 6 inches wide to as much as 16 inches wide. The wider the blade, the wider the wood stock the jointer can cut.
Cutting heads feature multiple blades. Smaller benchtop jointers have two or three cutting blades, while larger cabinet-style jointers have as many as four. The more blades, the smoother the cuts.
Most benchtop jointers can cut to a maximum depth of ⅛ inch, while commercial jointers feature depths up to ½ inch. The greater the depth, the fewer passes are needed to flatten a warped or an uneven board.
Cast-iron construction makes many jointers heavy and difficult to transport to a job site. Once your cabinet-style jointer finds a home in your workshop, you won’t be able to move it easily. These massive power tools weigh between 250 and 500 pounds.
A benchtop planer makes the lightest option for a jointer, but even some of these can weigh upwards of 60 pounds. Though heavy, benchtop jointers come small enough to transport to a job site.
When shopping for jointers, you’ll notice that some models feature straight blades, while others have a helical or spiral cutter head. Straight blades use two or more rows of blades that run straight across the cutting head. Benchtop jointers typically use this style of cutting head. They create smooth cuts but tend to wear out quickly and require replacement or frequent sharpening.
Some cutter heads use a helical or spiral-shape blade arrangement, which creates a smoother finish on the wood’s surface. Spiral or helical cutter heads have a spiral formation around the cutting cylinder, not unlike the double helix of a DNA strand.
With a spiral cutting head, each blade remains parallel to the axis of the cutting cylinder. With a helical cutter head, each blade sits 14 degrees off the cylinder’s axis, which creates a very smooth finish.
Given that jointers remove significant amounts of wood to flatten and smooth boards, they create an enormous amount of sawdust. A dust collection system will keep your workshop clean and the air breathable.
Look for power jointers that include large ports for removing sawdust. Smaller benchtop jointers feature 2-inch dust collection ports, while large cabinet-style jointers include dust collection ports as large as 4 inches in diameter.
While power jointers rank as one of the safer power tools because the wood stock or a retractable guard covers the blades while they cut, they also offer additional safety features.
Some include push handles that allow users to guide the wood through the blade without using their bare hands. They also feature large “off” switches positioned in an easy-to-reach place, which allows users to quickly shut off power to the blade when needed.
Some jointers offer additional features that make them easier to use, such as large knobs that allow for quick and easy adjustment of the feeder table height and the adjustable fence angle.

Most benchtop jointers feature a 6-inch two-sided cutting blade—adequate for most home woodworkers. Wahuda Tools takes it up a notch with this 8-inch helical-style four-sided blade. With its wider cutting edge and spiral shape, this blade removes wood more evenly and leaves a smoother edge than standard two-sided blade jointers.

How We Chose the Best Jointers
In researching more than a dozen different jointers, we considered a variety of factors. A good jointer should have a motor that spins the blade fast enough to make smooth cuts. With that in mind, we stuck with jointers that reach a max speed of at least 10,000 rpms. Jointers are typically used to plane larger pieces of wood, so table length is important. For that reason, we leaned toward tables that were long enough to support longer workpieces.
In addition to a long table, a good jointer should also have a fence that easily adjusts to cut at different angles. Finally, since jointers create precision cuts, it’s crucial that they be made from sturdy materials such as cast iron that won’t warp or bend over time.
Whether you’re unsure how to use a jointer or wondering how a jointer differs from a planer, read on for answers to these and other commonly asked jointer questions.
Q: How do you sharpen jointer blades?
While sending out your jointer blades to be professionally sharpened is an option, it can be costly and put your jointer out of commission for days or weeks. You also may not be happy with the results when you get them back.
If you want to sharpen the blades yourself, you can use a simple jig that will allow you to hold the two knife cutter heads in place and sharpen the blades without even having to uninstall them. While you can purchase such a jig, you can also create one using a small block of hardwood that fits in the gap between the table and the cutter and a dowel that blocks the blade and prevents the cutter from turning. After creating or buying a blade jig for your jointer, you can sharpen the blades yourself:
- Cover the outfeed table’s edges with thick tape, so they aren’t damaged during the sharpening process.
- Once you’ve locked the blade in place with the jig, you’ll need to move the cutting head into the proper depth for sharpening. Place a scrap piece of wood on the cutting table, and lower the outfeed table until the blade just makes contact with the wood.
- Using a 600-grit diamond sharpening stone, begin sharpening the blade by placing the stone on the blade, then draw it back in the direction of the outfeed table.
- Continue until you create a small bevel across the length of the blade. Use a magnifying glass to help you examine the blade.
- Switch to a 1200-grit stone and repeat the above process.
- Once you’ve sharpened the blade, remove the jig, rotate to the next blade, replace the jig, and repeat the process until you have sharpened all of the blades.
Q: How do you use a jointer?
Follow the directions below to properly operate a jointer:
- Begin by using a shop square to make sure the joint between the outfeed table and the guide fence is exactly 90 degrees. The point of a jointer is to make a perfectly square edge. If this joint isn’t 90 degrees, that won’t be possible.
- Adjust the depth dial to the desired setting.
- Position the wood stock on the infeed table with the crown side up, then turn on the jointer. Make sure to cut the face first, followed by the edges.
- Keeping the wood stock firmly against the fence, push the lumber through the cutter using push pads.
- Next, cut the other face, followed by both edges.
- If done correctly, you should end up with a perfectly square piece of lumber with four smooth sides.
Q: What is the difference between a planer and a jointer?
Although a jointer and planer both remove wood from the sides of wood stock, a jointer is designed to take bowed or uneven lumber and make it straight and square. A planer removes larger amounts of wood, taking a thick board and planing it down to the desired thickness. To use a planer, one side of the board must already be flat.
