Powerful and precise – the Einhell cordless biscuit jointer in a practical test

If you're a true DIYer at heart, then your motto will be "Why buy furniture when you can build it yourself?" If this is you, then a biscuit jointer should absolutely be part of your basic equipment! With flat dowels and grooves, you can create very precise and robust connections between two pieces of wood, and that's where the biscuit jointer comes in. If you don't have one yet or want to replace your device with a new one, you should take a closer look at the Einhell cordless biscuit jointer TE-BJ 18 Li. We have delved into the details of this handy cordless jointer in the practical test and explain which features you can look forward to and what you should pay attention to when working with biscuit jointers.

Precise grooves and flat dowel connections: These are the Einhell cordless biscuit jointer's real party pieces.

What the cordless biscuit jointer can do

Milling without height adjustment

The Einhell cordless biscuit jointer is a real all-rounder thanks to numerous adjustment options. Almost freehand, grooves for flat dowel connections can be milled as no height adjustment is carried out beforehand.

Milling with height adjustment

An exact height at which the groove is to be milled can be set beforehand by means of infinitely variable height adjustment. Thanks to presetting, you can attach the cordless cutter to the workpiece and it will no longer slip out. This is because a slanted groove or a groove milled at the wrong height results in an unclean, slanted connection of the two workpieces at the end.

Groove milling

Milling long or circumferential grooves is also no problem with the Einhell cordless biscuit jointer. The milling cutter can be guided precisely and straight along the workpiece thanks to the solid aluminium angle guide together with the height adjustment.

Mitre milling

Thanks to the infinitely variable angle adjustment, the cordless biscuit jointer is also suitable for mitre milling. With the help of the scale, the milling angle can be set up to a maximum of 90°. This means that both individual grooves for flat dowels and long grooves can be mitred. So, DIY furniture building is no longer a barrier!

Expert tips: What should you pay attention to when working with a biscuit jointer?

Since the Einhell cordless biscuit jointer already comes with a milling cutter blade, you can start working immediately. Nevertheless, you should always make sure that you are using the right suitable milling cutter blade. This differs depending on the material or type of wood. When purchasing additional milling cutters, make sure that they are recommended for the material for which they are used and that they are compatible with the milling cutter blade holder on the cordless biscuit jointer (diameter 22 mm).

Since you can use the six-stage milling depth setting to determine the milling depth depending on the dowel size, you should also know how to select the right type of flat dowel. For example, a Type 0 flat dowel is recommended for very thin boards with a thickness of at least 10 mm. Type 10 is suitable for wood pieces up to 15 mm thick and Type 20 is generally used for thicker workpieces from 15 mm thick. With the other three possible milling depths of the cordless biscuit jointer, you can determine the depth of a groove to be milled. A maximum milling depth of 20 mm is possible.

During milling, wood dust and chips are swirled up. Therefore, when working with a biscuit jointer, you should always work with safety goggles, a dust mask and, ideally, ear protection, because when milling in wood things can get noisy.

If you do a lot of work with wood and build your own furniture, you won't want to be without the cordless biscuit jointer.

Summary: The Power X-Change family has been expanded by another must-have

The cordless biscuit jointer TE-BJ 18 Li is another high-performance and high-quality device among the ever-growing range in the Einhell Power X-Change family. If you already have one or more PXC batteries and like to work with wood in your workshop, you shouldn't wait any longer, because the biscuit jointer impresses across the board in our test.
