Biscuit joiner review for woodworking

Biscuit joiners are power tools that serve a particular purpose: they cut slots into the wood, through which “biscuits” are inserted.

Biscuits are flat wooden discs that when inserted into the slots secure two different slabs of wood together. The combination of glue and the biscuit expands with PVA glue to tightly clamp itself to both surfaces.

History of using biscuit joiners

Biscuit joiners have been around since the early 1960s when a Swiss woodworker named Hermann Steiner developed them.

Additionally, it was Steiner who established the Lamello brand, which was responsible for some of the most highly-regarded professional biscuit joiners on the market.

What about plate joiners?

In principle, plate joiners are quite similar to angle grinders.

Instead of the diamond or abrasive cutters found in angle grinders, however, the best biscuit joiners typically have a tungsten-carbide tip (TCT) blade.

Moreover, they have steel “fences” that stabilize the unit and ensure evenly raised slots.

Where to use biscuit joiners?

Biscuit joiners are pretty rudimentary in function–they pretty much only let you cut slots into slabs of wood. Even so, this basic function enables for a pretty broad range of carpentry and woodworking tasks.

With a quality joiner in your shop, you can attach two pieces of wood to make a wider board, make neatly fitting joints, and even assemble strong and durable shelves and cabinets. For such a seemingly simple tool, the range of things you can create with a premium electric joiner is pretty impressive.

1. Consider the brand.

Biscuit joiners made by Dewalt, Makita, Festool, and Lamello are among the best tools you can buy at any price. As with any power tool, it is always worth going with a professional quality unit as opposed to a DIY model, even if it is strictly for home use.

With plate joiners made by these manufacturers, you could generally expect better overall quality and more accurate results.

2. What’s the rated durability?

Biscuit joiners are pretty simple tools, but they will undergo some heavy use.

Make sure that any biscuit joiner you buy can withstand regular heavy use without breaking down or falling apart.  

3. Stick to a standard-sized cutter.

Always go for a biscuit joiner that gives you the option to cut different-sized slots. You will generally want to go for the largest biscuits that your workpiece will accommodate, but there may be times when you will need to use smaller biscuits.

4. Make sure to have enough power.

Your biscuit joiner should have sufficient power to cut through hard, heavy, and dense woods cleanly and efficiently. This is especially important considering that making biscuit joins typically involves cutting into hard and heavy material.

5. Pay the right price.

Biscuit joiners are relatively inexpensive but don’t go for the cheapest model you can find.

A decent mid-priced model isn’t that much more expensive than the budget options, and they will pay off in terms of better performance, longer life, and useful attributes.

Electric joiners are fairly simple tools that perform a single basic function: cut slots into wood.

These tools have a “fence” (usually made of heavy stainless steel) that you press flush against the edge or surface of the piece of wood where you want the cut.

Plate joiners have a sharp cutting blade that pushes against the wood when the power is switched on.

Starting with the Makita PJ7000, it runs on a 700-watt motor that spins the cutting blade at 11,000 RPM, ensuring smooth and precise cuts.

It boasts one-touch stop settings for #0, #10, and #20 biscuits, and additional depth settings for other standard biscuit sizes.

Blade changes are fast and easy with the built-in shaft locks and clamp screws.

The fence itself is easily adjustable to 0°, 45°, and 90° angles. Likewise, the PJ7000 is equipped with a rack and pinion vertical fence system that ensures accurate adjustment of the fence.

The Makita PJ7000 is easier to work with than the larger-handled Dewalt alternative while being in the same price bracket. 

However, if you want to get the best biscuit cutter money can buy then you can consider the Lamello Classic x 101600 over the Festool. This is better made better and cheaper, but the Lamello classic x is still is not a cheap tool.

The Lamello classic can do extremely accurate, clean, and fast cuts for biscuit joining jobs, as the original joining tool on the market.

It is extremely well made and a pretty impressive tool to use.

Coming back to cheaper options the DeWalt DW682K is still an excellent choice for working with hard and dense woods.

It can make very accurate slots due to the dual rack design combined with a pinion fence.

This system ensures that the blade is positioned correctly and that the fences are perfectly parallel, so you get seamless and accurate joints.

The one-piece fence can be adjusted from 0° to 90°, allowing for a wide variety of cutting depth and angles.

If your preference is Dewalt here it is.

The Festool 574432 is a little pricey but employs an easy-to-use depth control that helps in fast and accurate adjustment to any of five mortising depth stops. It is armed with a pivoting fence that facilitates cutting angled mortises, with a range of 0° to 90°.

Furthermore, there are positive stops for cutting at 22.5°, 45°, and 67.5°. There is a one-of-a-kind range for adjusting the width of the mortise, making it easy to cut along panels seamlessly.

If you are after a cordless option the Makita XJPo3Z features six depth settings, including one-touch stops for the most common biscuit sizes.

The Makita XJP03Z is a cordless unit with enough power to compare to some of the best biscuit joiners on the market. 

It boasts an innovative Star Protection Computer Control system that improves performance and ensures longer battery life.

This system is responsible for constant monitoring and data exchange between the tool and the battery, preventing overloading, overheating, and over-discharging. Click the link to find out more.

Biscuit joints are pretty strong and versatile and can support fairly heavy loads. You can, therefore, use biscuit joiners to create a wide variety of furniture [1], from tables and benches to bookshelves and even cupboards.

Biscuit joiners are useful for any task that involves joining slabs of wood together. Although most woodworkers use them to join two pieces of wood side by side, they can be used to make butt joints and for joining the edge of a slab to a flat surface, as you would when making a shelf.

Even if you opt to use glue [2] to attach two pieces of wood, using biscuits will help ensure proper alignment when you clamp the individual pieces together.
