If you do that often, say, at job sites in homes and want it sparkling clean, order a second chip catcher (#492732 $20)
. The chip catcher's plastic catcher is easily cut with a hacksaw. In fact, it comes with an embossed line for a wider angle. You could cut a second one to leave only 85 degrees of 'catch'. While not as good as 170 degrees of 'catch', I'd bet it would help a little, but overall, like the other said, fines are taken care of, but chips require a little effort.
