Circular-Saw-Blade Sharpener - Small Boats Magazine

If Harbor Freight would offer wheels with finer grit, there’d be hope for the sharpener, but the 180-grit wheels that are supplied with the machine and available as replacements are brutal on carbide saw teeth. I have two diamond sharpeners from EZE-Lap Diamond Products with four grades of diamonds on aluminum handles about the size of tongue depressors. The grits are rated from 250 to 1200, and the 250 grit is designated as “coarse.” That puts the 180-grit wheel on Harbor Freight’s circular saw sharpener into the proper perspective—coarser than coarse.

This flexible fine-cut saw is great for cabinet work, flush cutting (dowels), general fine cutting, mitering, plywood, stair systems, and undercuts (door jam/casings). It can be used for flexed or flush cutting and features the pull-to-cut method for faster, cleaner, easier, and safer sawing. The pull-saw teeth have three cutting edges that are precision diamond-cut, not merely stamp-cut. The saw handle is weather-resistant high-impact ABS plastic.
