Tips for Buying a Biscuit Joiner

If you’re a hobbyist or does DIY tasks only on occasion, a basic plate joiner will suffice. The standard plate joiner has a 4 inch blade with 4 to 6 teeth, and at the very least the tool should be able to cut channels for #20, #10 and #0 biscuit sizes. The more advanced joiners have support for other biscuit sizes, but for beginners these will be enough. There are also some biscuit joiners that swap the standard 4 inch with the 2 inch blade, which can be useful if you’re going to work on small biscuits and grooves.

As the reviews above indicate, there are different biscuit sizes and the ones you’ll use depend on the type of work you do. The most popular plate joiners are capable of cutting slit shapes for a variety of sizes. However if your needs are precise you’ll need another tool like a detail joiner to finish off the job.

One of the most important features of a plate joiner is the blade so make sure it’s of high quality, i.e. carbide tipped or made by a reputable manufacturer. You should also check the tool’s fence and how it pivots at various angles: the placement of the fence is parallel to the blade, and you should be able to center the blade halfway along the board’s threshold.

The joiner fence tilt determines how well easily you can do precision cuts with beveled ends and angles. The majority of fences tilt at 45 degrees, but others are capable of cutting at other angles. If you’re new to biscuit joining you don’t need to worry about this, but if you’re going to work with complicated sections, you’ll have to get a plate joiner with a fence that can handle micro angles.

Pivots is something you’ll often come across when shopping for these tools, and while there are a lot of options, the most popular is 90 degrees as it allows for miter cuts. There are also plate joiners that have fences capable of shifting up to 135 degrees, and with this you’ll be able to create cuts on the piece’s outer edge rather than just the interior section.

Fence enhancements is not for everyone, but if your tool has that feature you’ll be able to attach all kinds of materials of varying sizes while making sure the outer edges matches, all without making any tweaks to the fence. Depending on your needs, it might be a good idea to buy a joiner with a fencing system that can lower or raise the tool with precision.

The flush cut is another important feature that you’ll want to look at, as some of these tools make a slight shift when the setting is at zero degrees. Avoid these plate joiners because fitting in the slot might cause problems.


So which is the best biscuit joiner? Any of the ones we reviewed here qualify, and it’s really up to you to decide. The point is you cannot go wrong with any of the top five here, as there are reasons why they’re considered the cream of the crop.
