Burr-Free Cuts in Aluminum
Cutting aluminum on a table saw isn't a problem, as long as you have a carbide-tipped blade. But it does tend to leave a jagged edge (see top photo).
In the past, my solution was to file the edge smooth. But while cutting aluminum angle recently, I inadvertently cut through a manufacturer's sticker on the workpiece. Once the cut was completed, I noticed the edge underneath the sticker was perfectly smooth.
Intrigued, I ran a strip of electrical tape down the length of the next piece of aluminum angle (see bottom photo). Then I ran the angle through the blade, tape and all. The tape eliminated burrs on the edge, resulting in a smooth, clean cut. Now, I no longer have to spend valuable shop time filing the edges clean after cutting aluminum stock.
