So if you have a vac that sucks 100 CFM(and let's skip how those specs are derived) you have positive suction and dust and chips will be collected as long as we have a sealed system(like a mortise that's covered by the router base and a router with reasonable dust guards). I've never seen any airflow specs on router motors but, for the sake of argument, let's say X router blows 80 CFM through the motor. These fans move a lot of air turning at 20K+ RPM so anything you hook up for dust collection obviously has to move more air than the tool expels with enough to spare to bring the chips along with it. ![]() The main issue is that you have a tool running at high speed with a fan that takes in room air at the top, moves it over the motor for cooling and expels it at the working end. And let's not forget the little pieces you have to put in to surround the bit(and take out to change the bit) so the DC works as advertised. And then there's the vac hose, where it's attached and how it's supported to consider. You can get excellent results in some cases(like a mortise where the cut length doesn't go past the edge of the base), pretty good collection on dadoes and grooves, and anywhere from non-existent to halfway-decent on edge profiling(depending on what you want to put on the router that always seems to hang up on a corner or get in your way).

I have 11 routers total and most are other brands, but the DeWalt 611 and 618 routers are the ones that get used the most. I also have the 611 two base router package with the dust accessories for both bases and even though it only takes 1/4" bits I find that I prefer it for lighter work because of it's light weight and balance, even over my DeWalt laminate trimmer. It would be nice if they offered a vacuum accessory for the 618 fixed and D handle bases like the one available for the DW611 fixed base, but I doubt they ever will. I frequently use the D bases when using my Leigh D4R and FMT Pro jigs. I've found the D handle base to be very comfortable to use because the handle gives me more control. ![]() In the three base package you get the contents of the two base package plus a D handle base which is a fixed base, but with a D handle and trigger switch. ![]() I have three 618 routers, one is the two base package and I have two of the three base version. You just set the depth a little differently, and you can leave it plunged and locked if you really want the effect of a fixed base router. Yes, the DeWalt 618PK is a good router and very versatile, and you can use the plunge base in place of the fixed base.
