In European terms the DW is by far the better tool, albeit more expensive. Basically it has a much superior collet design, but it also comes as standard with an adaptor plate
to take the Elu MOF96/deWalt DW615/Trend-type
guide bushes - probably the widest range of any type of guide bush
available anywhere with a number of third party manufacturers also producing compatible bushes, such as Axminster
. In addition the plunge depth setting is one of the better designs out there with excellent micro-adjustment.
Having used these two models back to back on the bench for Corian work a few years ago (always very hard on routers) I'd have to say that the DW wins hands down in my mind. In comparison with the DW the Hitachi M12V2 looks like a Reebok trainer on acid (which I don't like), but worse to my mind is the fact that it is an elephantine (physically overly large) tool whilst being no more powerful than the DW (current type 6 DWs are rated at an identical 2000 watts). The lack of a standard guide bush holder is another reason to mark it down in my estimation.
In terms of dust extraction neither is that special - in fact to get good dust extraction in a 1/2in router at this power level you really have to look to the Festool at an eye-watering price. DW do make a smaller 1/2in router, the DW622 (based on the DW621 and the earlier Elu MOF97 designs), which has much better dust extraction and is pretty compact, but it is only rated at 1400 watts which isn't really enough for heavy joinery work IMHO
If table routing is a requirement I know that a £15~20 fine depth adjuster is available for the DW625 (ref DW6966) - they work OK - but if you want above the table adjustment then there is a varient of the DW625 made for Trend, called the Trend T11ek
, which has such a facility and which will in addition accommodate guide bushes up to 70mm. The Trend version alos features an 80mm plunge depth (as opposed to the 65/70mm of the DW625)
Am I a fan of the DW625, then? Yes. I've had a MOF177e since the mid 1980s, bought my second one in the late 1990s and more recently bought a DW625. I can still get most of the essential spares for all of them - not that I much need to because main failures to date have been bearings, brushes and collets/nuts - all the result of much usage. I can't think of another router available in the EU that you could say the same for - other than a couple of other ex-Elu designs
