6 Best Jointers for Woodworking
Achieve flawless, seamless wood joints. Our guide reviews the 6 best jointers for creating the flat, square edges essential for heirloom-quality work.
You’ve probably been there, trying to join two boards for a new gate or a cold frame lid, only to find a frustrating gap you could slide a nickel through. No amount of clamping or glue can fix a board that isn’t truly flat and square. This is where a jointer becomes less of a luxury and more of a necessity for building things that last.

Why a Jointer is Key for Heirloom Woodworking
A jointer does one thing, but it does it better than any other tool: it creates a perfectly flat face and a perfectly square edge on a piece of lumber. Think of it like plowing a field before you plant. You need a clean, level starting point, or every row that follows will be crooked. Without that true reference surface, every cut you make on the table saw or miter saw inherits the imperfections of the board.
This is the secret to tight, seamless joints that look professional and hold up for decades. When you’re building a workbench that needs to be dead flat or a cabinet door that must hang perfectly square, the jointer is the first stop after the lumber rack. It’s the difference between a project that looks "homemade" and one that has the tight tolerances of heirloom-quality work. You simply cannot get that level of precision by hand-planing or running boards through a planer alone, as a planer only copies the existing, often warped, surface.
Grizzly G0857: Top Choice for Serious Hobbyists
The Grizzly G0857 is a workhorse, plain and simple. It’s built like a piece of farm equipment—heavy, stable, and designed to do its job without fuss. With its 6-inch width and a long cast-iron bed, it gives you the stability needed to flatten boards for larger projects like barn doors, benches, or sturdy shelving for the pantry.
This machine is for the person who has moved beyond small repairs and is tackling substantial builds. The built-in mobile base is a huge plus in a crowded barn or workshop, letting you move it out of the way when you need the floor space. While it’s not the biggest jointer out there, its combination of power, bed length, and a helical cutterhead offers a massive step up from any benchtop model. It’s a serious investment in your workshop’s capabilities.
WEN JT630H: The Best Compact Benchtop Jointer
Not everyone has the space for a freestanding machine. The WEN JT630H understands that reality perfectly. It’s a compact powerhouse that sits on your workbench, ready to true up boards for smaller projects like picture frames, beehive boxes, or repairing a broken chair leg.
The key feature here is its spiral cutterhead, which is rare for a jointer at this price point. This gives you a smoother finish with less tear-out, even on figured wood you might have milled yourself. The tradeoff is capacity. Its shorter bed means it’s not ideal for flattening long boards, as you’ll struggle to keep them stable. But for the countless small tasks around the farmstead that demand precision, this little machine is an incredible value.
Jet JJ-6CSDX: Long Bed for Unmatched Accuracy
When it comes to jointing, bed length is king. The longer the infeed and outfeed tables, the more support the board has, and the flatter the resulting face will be. This is where the Jet JJ-6CSDX shines. Its extra-long bed makes it the go-to choice for anyone working with boards over four or five feet long, which is common when building furniture or long workbenches.
This machine is about one thing: accuracy. Trying to flatten an 8-foot board on a short-bed jointer is a lesson in frustration. The Jet’s design, with its quick-set knives and robust fence, is all about repeatable, predictable results. It’s a tool for those who measure twice, cut once, and expect their joints to be flawless. It’s a significant footprint in the shop, but the precision it delivers on long stock is something you can’t achieve otherwise.
Powermatic PJ-882HH: The Ultimate Helical Head
If you’re looking for the best of the best, you’ll end up looking at the Powermatic PJ-882HH. This is the kind of machine you buy once and pass down to your kids. Its 8-inch width gives you more capacity, but the real star is the Byrd helical cutterhead. It provides an almost glass-smooth finish, runs quieter than straight-knife models, and if you nick a cutter, you just rotate one small insert instead of replacing an entire blade.
This is a professional-grade machine, and it carries a professional price tag. But for someone who spends significant time in the workshop and demands perfection, the time saved and the superior quality of the finish are worth it. It’s the difference between a good tool and a great one. The sheer weight and build quality mean it’s incredibly stable, eliminating vibration and ensuring every pass is perfect.
PORTER-CABLE PC160JT: A Reliable Workshop Staple
Sometimes you just need a tool that works, day in and day out, without a lot of bells and whistles. The PORTER-CABLE PC160JT is that tool. It’s a straightforward, reliable benchtop jointer that has been a staple in small workshops for years for a good reason. It’s easy to set up, easy to use, and does a solid job of creating flat faces and square edges on boards for most common projects.
This is an excellent first jointer. It will teach you the fundamentals of milling lumber without the intimidating size or cost of a larger machine. While it uses traditional straight knives and has a shorter bed, it has more than enough power and precision for building cabinet faces, small tables, and other household projects. It’s the dependable pickup truck of benchtop jointers—not the fanciest, but it will always get the job done.
Jet JJP-12: The Best Jointer/Planer Combo
Space is often the most valuable commodity in a workshop. The Jet JJP-12 addresses this head-on by combining a 12-inch planer and a 6-inch jointer into a single machine. This is an incredibly efficient solution for someone who needs to take rough lumber all the way to a finished, dimensioned board (S4S – surfaced four sides) but doesn’t have room for two large, separate tools.
The primary tradeoff with a combo machine is the changeover time required to switch between jointing and planing functions. It takes a minute or two, which can disrupt your workflow if you’re constantly switching back and forth. However, if you batch your operations—jointing all your boards first, then converting the machine to plane them all to thickness—it’s a brilliant space-saver. The helical head is a fantastic feature, delivering a clean finish and making this a powerful, versatile heart of a small, productive workshop.
Jointer Safety and Essential Maintenance Tips
A jointer is not a tool to be taken lightly. The cutterhead spins at thousands of RPM, and it demands your full attention and respect. Always use push blocks. Never, ever let your fingers get close to the cutterhead guard. Your hands should only be used to guide the wood on the infeed side, far from the danger zone.
Keep your jointer clean and maintained, just like any other piece of critical equipment. Regularly check that the fence is set to a perfect 90 degrees. The tables should be kept clean and waxed with a paste wax to reduce friction and prevent rust, ensuring boards slide smoothly and safely.
Finally, sharp knives are safe knives. Dull knives require more force to push the wood, which can lead to slips and dangerous situations. Whether you have straight knives that need sharpening or a helical head with rotatable inserts, keeping them in top condition is essential for both safety and the quality of your work.
Ultimately, choosing the right jointer is about matching the machine’s capabilities to your space, your budget, and the kind of projects you plan to build. A jointer isn’t just another tool; it’s the foundation of precision woodworking. By starting with a perfectly flat and square board, you set every subsequent step up for success, ensuring the things you build are not only beautiful but strong enough to last a lifetime.
