cuts aluminum, but not as well as you'd think [Posted on 2008-01-22] I bought the Metal-Cutting XBit to freehand cutting in 0.125" sheet aluminum and found it workable, but barely. The bit could not penetrate the plate to start a cut in the middle of the sheet, requring me to start every cut with a power drill instead. After less than an inch of travel, the bit was clogged with melted aluminum chips. After cleaning the bit with an icepick, I sprayed the surface of the aluminum with WD-40 for cooling and lubrication. By spraying the work area regularly, I was able avoid clogging the bit for several hours of subsequent use.
