Porter-Cable - 557 Biscuit Joiner
This machine has the largest fence of this group, which is an advantage for general use. But the large opening near the blade makes the tool unwieldy on small workpieces. Fence-height adjustments are slow, but the fence remains parallel and holds its settings. The plunge mechanism is smooth and solid. A unique feature is that the top handle is attached to the front of the machine—not to the moving barrel—which gives you better control as you plunge.
