The Best Biscuit Joiner

Biscuit Joiner Reviews

Our Top Pick is the Porter Cable 557

A Biscuit Joiner (Also known as a Plate Joiner) is a woodworking tool used to join two pieces of wood together. If you do not want to connect wood with screws, nails or bolts, then you need a biscuit joiner. This tool allows you to make the internal plunges that “hide” the joint and secures the wood pieces together.  When you want to join two pieces of wood together you are often faced with the problem of being able to see the joiners on the outside of the wood. That is where a biscuit joiner comes in handy. A Biscuit joiner works by cutting a slot into the wood so that a little wooden piece known as a biscuit can be inserted into each side of the material securing the wood joint. Biscuits come in various sizes and are made of various materials in order to hold different types of material together.

Another feature that a biscuit joiner often offers is a fence system which allows the user to make angled cuts. You can set the exact depth and make a plunge cut that will tightly fit the biscuit. Biscuit joiners are often used for furniture building, interior and exterior trim, door panels, table tops, furniture backs, face frames, deck planters, post wraps, and so forth. The biscuit joiner is a fast and simple way to join two pieces of wood safely and securely without using nails or screws.

We evaluated 22 biscuit and plate joiners and after a thorough and extensive search, the biscuit joiner that stood above the rest was the Porter Cable 557. This tool has enough power to get the job done. It has exceptional plunge accuracy and is able to make a full range of depth stops to meet all your needs. The blades are fast and easy to switch on and off, and the lightweight design reduces fatigue. This machine has all of the necessary functions to make your woodworking projects come alive.

Who Should Buy This

A Biscuit joiner would be the perfect tool for anyone who works with wood professionally or recreationally. The versatility of the biscuit joiner gives the user a tool that can be widely used for making plunge cuts, creating inside joints that are required for top quality furniture, and other wood working projects. You can build picture frames, furniture, and other projects that require joints. By using a biscuit joiner you gain more secure joints and a more professional finish.

What Makes a Good Biscuit Joiner?

When selecting a biscuit joiner, you do not want to focus on price. Less expensive models struggle with both comfort and accuracy. Precision is essential with this tool. Being off, even a centimeter, can result in a joint that is not secure. Given the nature of the biscuit joiner one of the most important aspects of this power tool is accuracy. Obtaining accuracy requires a comfortable grip so your hand does not slip. You also need accurate plunge measurements that are easy to read as well as fencing and levers that stay in place so that the wood does not move during the cut. When joining two pieces of wood together you will need them to be aligned exactly to ensure a proper joint.

Biscuit JoinerA center plate helps you align your material with accuracy. A center plate is the piece at the top of the blade that contains markings that show the exact center of the blade. Having this feature will guarantee that the cut you make will go precisely where you need it.

Another feature you will want to look for is the fence. Fences offer the ability to align your machine with precision. The fence adjustments should be beyond 90 degrees to give you more flexibility so you can meet your project needs. You will need to be able to angle your machine properly to achieve the cut you need to make. This is beneficial for perpendicular joints, vertical joints, and horizontal joints. The fence will allow you to rotate the tool and secure the angle tightly for an accurate cut.

Another important feature is blade size. Using the proper blade for the job will help ensure the plunge is exact. Tools with larger blades give you more options but can be more difficult to handle. Four-inch blades are the most common size and will enable you to make most cuts. Six and eight inch blades might be required for larger projects and professional woodworkers. For most homeowners and DIYers, the four-inch blade will give you the variety of cuts you need without requiring a larger tool.

In the case of a biscuit joiner, a bigger motor is not always better. When making precision cuts a smaller motor will mean less weight which can lead to greater accuracy. The best quality biscuit joiners contain 5-7 amps and rotate at approximately 10,000 RPMs. This is a safe and powerful combination that when used properly will provide beautiful, clean results.

We then looked to real world experiences and extensively searched customer reviews and expert advice to see which biscuit joiners held up. Lastly, we turned to Amazon reviews to get feedback from non-professionals and learn about their experiences with our top choices.

Who Else Likes It

It makes accurate cuts whether using the base or the fence for reference, and it’s easy to quickly set the fence angle and height…If you want to use face-frame biscuits, switching to the smaller blade is a breeze.”

This Old Workshop tested the Porter Cable 557 and came to this conclusion, “The Porter Cable 557 works smoothly without bogging down in the cut. The extra adjustment in the fence going all the way to 135 degrees. It also gives a better grip on the cutting face and has an acrylic plate for double thick biscuit joints and a face frame setting. The ergonomics of the 557 is also superior than its competitors.”
