Scoring saws are ideally suited for cutting veneered plywood or melamine sheet goods without tearout, especially on the lower face. They perform this trick by incorporating a small, counter-rotating sawblade mounted in front of the cutting blade. The small blade makes a shallow climb-cut in the bottom face, and the larger blade cuts through the material. The result is a perfectly clean cut. The problem has been that scoring saws were available only on very expensive, industrial-grade tablesaws. The Modulus SS-10 scoring-saw attachment will fit most 10-in. cabinet and contractor-style tablesaws. The assembly mounts on the tablesaw arbor like a conventional blade with the arbor directly driving the 6-in. blade, while the 2-in. blade is powered by a ribbed belt off the 6-in. blade. Cutting capacity is 1 in. at 90° and 3?4 in. at 45°. The SS-100 allows you to use your splitter assembly. Installing the unit for the first time will require about an hour. After the initial setup, it takes no more time to install or remove the SS-100 than it does a regular sawblade. The two-piece, 2-in. scoring blade can be adjusted easily for width and alignment, although the one I tested was set up perfectly out of the box. I ripped and crosscut cherry veneer-core plywood, red-oak veneered MDF, and melamine panels without a hint of tearout. The attachment is available directly from the manufacturer.

Festool Rotex FEQ-Plus Random Orbital Sander

The Festool Rotex is a top-of-the-line choice. On its coarse setting, it removed stock nearly twice as quickly as the second-fastest model. But that speed doesn’t mean you’ll have to wrestle with it. It’s no huge task to control it with two hands, and its long body gives you plenty of room to find a sweet spot while holding it.
