PORTER-CABLE 5558 4-Inch, 6 Tooth Plate Joiner Blade
Made to replace Porter Cable's model 557 plate joiner, this hardy blade has six strong carbide teeth for reliable, consistent cuts with every pass. It features a 7/8-inch arbor hole and four-inch diameter blade for rapid and efficient cutting of standard biscuit slots without sacrificing precision or control. To avoid replacement costs, this blade can be re-sharpened, and it affixes and detaches with minimal effort.
