Lamello invented the biscuit joiner and is still the standard that everyone strives for. They spare no expense to insure that they are providing the best possible tool, with heavy duty, precision everything. Everything from the fence to the bearings on this unit is heavy-duty, guaranteeing years of long life in any professional woodworking shop. Lamello’s unit has more detents and a finer adjustment for depth of cut and fence position than anyone else, with steps at 0.1mm; nobody else does that. They've also increased their motor size to 800 watts, making it the biggest motor ever put on a biscuit joiner.
As usual, Festool puts out a top quality product. This is a larger version of their well-known Domino XL Joiner. It has a maximum tenon size of about five and a half inches. Like their other tools, this one is designed to work directly with a dust collection system. Considering how much dust a biscuit joiner can make, that’s a nice way to work. The cutting action on this one is a combination of rotating and oscillating, which makes clean repeatable mortise cuts every time. Easy adjustment of the mortise width at the turn of a dial. It comes with optional trim and cross stops for narrow stock and edge joining.
Makita is one of the top professional power tool companies today. Their biscuit joiner lives up to everything one would expect of their quality tool design and manufacturing. The vertical fence comes with a rack and pinion adjustment, for smooth, accurate, repeatable adjustment. Adjustments are protected with cam locks. Six different preset depth settings are available. To protect the workpiece, they've installed a rubber strip in the fence, a nice touch.
At 7.0 amps, this Porter Cable biscuit joiner is the heaviest duty unit we’ve listed. Even Lamello’s 800 watt motor isn’t as powerful as that. The greater power should equal longer life, especially if you’re cutting hardwoods regularly. The fence tilts up to 135 degrees, with a stop at 90 degrees. There’s a micro adjustable knob for height adjustment and 7 depth stops, making it the top unit in that category as well. Oh, and Porter Cable wants to make sure you can keep on cutting, so they supply you with 2 blades, instead of the 1 that everyone else does.
When DeWalt started their climb to regain their reputation as a manufacturer of quality professional power tools, they knew they had their job cut out for them. Well, as far as I’m concerned, they've made it. The tools that DeWalt’s been putting out over the last several years, show careful design and robust manufacturing. Building tools that professionals can use with pride, and with the expectancy that they’ll survive the rough environment of the workplace. DeWalt is so confident about their quality that they've put a 3 year warranty on this unit. That says a lot in and of itself. It comes with all the standard features and a 6.5 amp motor, the most common size in these quality biscuit joiners.
