Simply place the rail on top and cut vertically for fun I did not expect from such a cheap plunge to give you such confidence and ease without it what would I do. Dust collection not as good as makita festool but if you call the hole it collects dust much better. The rails are very good 2 meters. I did not cut 45 degrees of course never need 98 percent of the cuts are 90 degrees. And it also has a very good melamine disc 200 cuts so far and cuts well without marks. It is a tool. Only in natural wood may show fatigue and inferiority compared to the beasts metabo, festool, makita, maffel
