Editor's Review: Biscuit Joiners

by Roland Johnson

review date: October 1, 2001

Woodworkers in the market for a biscuit joiner have many models from which to choose, so Fine Woodworking decided to test a dozen of them. Results showed that the features to look for include a comfortable handle; an easy-to-operate switch; an adjustable fence that works smoothly, offers good support, and adjusts for angles you need; a turret stop that adjusts for the biscuit sizes you use; and a grip system that keeps the tool from sliding.

The Lamello Top 20 is the author’s favorite machine. It cuts slots that are perefectly parallel. The motor slides smoothly. A micro-adjust dial allows the cutter to be raised or lowered in 1/10mm steps, up to 2mm. However, the price is above the clouds.

As with most every other top grade tool I've purchased over decades, this was a budget buster at the time, but it's performed beautifully. I'm sure some of the less expensive joiners will do a great job and present the buyer real value for the money, but if you don't mind shelling out the bucks, the Lamello is hands down the best in performance and engineering. Great tool to use.


I have owned and used three other biscuit joiners, a Dewalt, Freud, and a Porter Cable. The Lamello is the best of all. The slide is smooth, position of the cut easy to adjust, and the biscuit is always perpendicular to the edge of the board. The down side is the cost of admission, but well worth it in my opinion.

I find this tool a pleasure to use whenever I plug it in.The dust extraction hose is a rip-off but the tool does everything it is said to do with uncanny repeatability.
