M-POWER TOOLS HAS INTRODUCED a diamond stone designed for sharpening carbide router bits. It’s small—the stone itself is just 1 in. wide by 3 in. long—and maneuverable. The elliptical handle, located close to the cutting action, allows you to apply cutting pressure more evenly and with great control. One side of the stone is 300-grit and the other is 600-grit, and both grits cut carbide quickly. I sharpened several bits with the stone, and it did a good job. When sharpening a router bit by hand, remember to take the same number of strokes over each cutter so that the bit remains balanced. If you manage this, the M-Power router-bit stone is the perfect tool.
