Not sure if you are taking about using the saw for aluminum or wood but, we bought one from home depot we cut 95% of our alumunum with it. We use a 60 or 80 tooth carbide tipped blade and it works like a champ. The saw leaves no burrs and is very accurate. Here is the saw we have
10" COMPOUND MITER SAW . We also have a horizontal band saw. Since we got the miter saw the bandsaw has not been used. You just have to be careful and make sure the material is clamped in well (like any metal cutting opperation).
