A biscuit joiner tool (also known as “biscuit jointer” and “plate jointer”) is a woodworking tool that craftsmen use to merge two pieces of wood together. It is useful for creating strong and precise joints in a variety of projects. 

The tool derives its name from the small, oval-shaped wooden pieces made of beech or particle wood called “biscuits.” This highly-dried and compressed wood, along with glue, helps in the joining process.

Biscuit Joinery

Biscuit joinery is essential for creating edge-to-edge joints, miter joints, and T-joints in woodworking projects such as cabinets, tabletops, and frames. It is valued for its capability to create strong, hidden joints that don’t require screws or nails. This is crucial when trying to achieve a clean and seamless appearance.

However, biscuit joinery is not the best option for extremely heavy loads or critical load-bearing joints, where traditional mortise-and-tenon or dovetail joints are more suitable.

Biscuit Joiner Tool Types

Here are some types of biscuit joiners:

  • Handheld Biscuit Joiner: This versatile and portable tool is the most common type of biscuit joiner. It usually has depth settings and an adjustable fence, which is useful for making precise cuts.
  • Stationary Biscuit Joiner: Unlike handheld versions, stationary biscuit joiners are fixed to a workbench or a dedicated stand. Moreover, they also often have larger motors, making them perfect for heavy-duty work and large professional projects.
  • Cordless Biscuit Joiner: A cordless biscuit joiner uses battery power to offer more mobility. This is great for job sites with limited power outlets, although it may offer slightly less power than corded models.
  • Mini Biscuit Joiner: A mini biscuit joiner tool is smaller and more lightweight. They are suitable for smaller woodworking tasks and are also great for beginners.
  • Dust Collection Biscuit Joiner: Many modern jointers come with a dust collection system. This helps minimize wood dust in the workspace.
  • Adjustable Biscuit Joiner: Some joiners can cut slots at angles other than 90 degrees. This is useful for creating beveled or mitered joints.
  • Multi-Blade Biscuit Joiner: While most biscuit joiners come with a single blade, some models have the option for multiple blade usage. This is suitable for cutting multiple slots in a single pass.
  • Dowel Joiner: Though not technically a biscuit joiner, a dowel joiner performs a similar function. Instead of using biscuits however, these tools create holes for dowels to be inserted, creating a different type of joinery.

Biscuit Joiner Tool Handling Safety

Like all power tools, biscuit joiners require utmost safety during operation. Here are some tips to help ensure a safe woodworking experience:

  • Train Properly: Seek training and guidance from a woodworking professional.
  • Wear Safety Gear: Wear the appropriate safety gear for protection.
  • Inspect the Tool: Check the joiner to ensure that it is in good working condition. Check for loose or damaged parts, and see if the blade is sharp.
  • Secure the Workpiece: Use clamps to secure the workpiece firmly to the workbench or table to prevent any movement while cutting.
  • Keep Hands Away: Use the handle and the grip for control, and keep your hands away from the blade at all times.
  • Disconnect Power: When not in use, disconnect the power before handling the biscuit joiner tool to avoid accidental starts. 
  • Use the Right Blade: Blades vary in size and tooth count so select the correct one for the workpiece.
  • Proper Blade Depth: Adjust the blade depth so that it’s just enough to create a slot for the biscuit. If it gets too deep, this can weaken the joint.
