Why Use an 8-inch Jointer?
Jointers are power tools used to straighten, flatten, and square rough-cut lumber to make it ready for final shaping and finishing. The “8-inch” here refers to the width of the cutter head, which is part of the tool that rotates and removes wood from the edge of the board.
While there are other size jointers, such as 6-inch and 12-inch models, 8-inch jointers offer the perfect balance between power and size. Here are the most common reasons for using an 8-inch jointer.
Increased Edge Joinery Capability
An 8-inch jointer’s larger cutting capacity allows you to join edges of boards up to 8″ wide. You can join the board on its face or visible side, up to eight inches wide. This means you can join boards for greater stability and strength in larger projects like tables or large desks.
Accurately Joining Longer Workpieces
Thanks to infeed and outfeed tables longer by 10 to 18 inches compared to a 6-inch model, 8-inch jointers allow for more precise jointing of longer wood pieces without additional support. As a result, projects requiring longer boards, such as bookshelves, can benefit greatly.
More Power for Faster and Efficient Jointing
An 8-inch jointer typically has 2-3 horsepower motors which deliver more power to the cutter head, letting you remove more material per pass when needed. It saves you time and effort by joining the boards faster and more efficiently.
Precision and Versatility
The 8-inch jointer also has a larger cutter head than the 6-inch model, so you get a more precise and accurate cut. And since you also get various cutting knives—standard, reverse, angle, and helical—you can achieve different finishes on the edge of the wood boards.
Longer Motor Life
In a shop with 220 volts, a jointer with an 8-inch drive will draw less power than one with 110 volts. This results in a longer lifespan for the motor with lesser maintenance.
Cost Savings
While they may require more upfront investment than smaller jointers, 8-inch jointers can save you money in the long run. This is due to their capacity for more work simultaneously, higher performance levels, and greater versatility across applications.

Buying Guide: What to Look for When buying an 8-Inch Jointer
Even with our top five 8-inch joiners in mind, there are still several factors you should consider before making a purchase. Here’s what to look for when buying an 8-inch jointer.
Purpose of the Jointer
The first thing to consider when buying a jointer is what the purpose of the machine will be. Will it be used for professional woodworking or just for hobbies? This will help determine your jointer’s size and type.
For example, if you’re looking for a jointer for commercial use, you’ll want to find the type with the largest and most powerful tables. On the other hand, a smaller jointer with a lower power output may be best for hobbyists.
Power
8-inch jointers come in different sizes and with varying power ratings. The most popular jointers are 8-inch models with a 6 to 7-1/2 horsepower motor and amp rating of around 10-11 amps. If you’re looking for a machine with more power, you may opt for an industrial-grade model.
Cutting Capacity and Speed
A jointer’s cutting capacity is determined by its cutter head size, the number of knives, and the maximum cutting depth. With a larger cutter head and more knives, you will be able to cut harder materials more efficiently and at a faster pace.
Type of Cutter Head
The three types of cutter heads are straight, spiral, and helical. Each one has its own advantages and disadvantages. Straight cutter heads are the most common but are also the noisiest. Spiral cutter heads are quieter and leave a better finish. The helical is the quietest and leaves the best finish.
Table Size
As important as the jointer’s table is its size. A smaller one won’t be as versatile as a large one when working on bigger pieces. You’ll also want to choose a jointer with an adjustable fence for precision angle cuts. Besides, some jointers can add extensions to the table for even more space.
Dust Collection
The best 8″ jointers must also feature an effective dust collection system. A jointer with a built-in dust collection system will make cleanup easier and improve the air quality in the workshop.
Safety Features
Safety is always a top priority. A jointer with a push-button switch with a large off the paddle, a rabbeting table, and a built-in mobile base can always improve the machine’s safety.
Price
Last but not least, the price. 8-inch jointers can range from around $800 to more than a few thousand dollars, depending on the features and power of the machine. Quality and performance generally improve as you spend more.
FAQ
If you have further questions about 8-inch jointers and their accessories, here are some of the most common ones.
6 and 8-inch jointers differ primarily in their cutter head width. An 8” jointer can handle wider boards & longer workpieces, have a more powerful motor, and longer infeed/outfeed tables compared to a 6” jointer.
The most common type of steel used in 8-inch jointers is high-speed steel. It’s known for its durability and is more resistant to wear than other types of steel. Besides high-speed steel, some jointers use carbide-tipped blades, which are also durable.
The price of 8-inch jointers can range from around $800 to $3,000 or more, depending on the features and power of the machine. Generally, the more you spend, the better quality and performance you can expect from the jointer.
It really depends on your needs and preferences. Both Rikon and Laguna jointers offer great 8-inch jointers, with several variations between models. So it’s best to compare the features and decide which suits your needs better.
An 8-inch spiral benchtop jointer is a smaller version of the traditional 8-inch jointers, designed for woodworking projects that don’t require as large a jointer. It comes with spiral cutters, ideal for cutting softwoods and hardwoods.
Conclusion
