Hi Hogarth
I currently have an 18V version of the ASCM for review from Fein as an outcome of my own Fein
saga.
The only other Festool drill I have to compare is the CXS which is by no means a viable comparison other than the ability to compare the CXS's version of Centrotec. One thing to note, the Fein changeable head function and Centrotec are not compatible.
The ASCM is a decent drill and its actually made in Germany; I mention this as this was the basis of my gripe on that link up there, however I also understand that the PDC is sourced from the Czech Republic for balance. I have the ASCD 18 impact driver and the ASB 18 combi/driver (as per the link); these tools are not of German origin and there is (in my opinion) a 'slight' difference between these and the ASCM but that's another conversation.
I've not used the ASCM too much as the point of the review was to ascertain its suitability for use in a wider project. The drill that was supplied for review had seen 'some' previous use and our concern was that if the drill failed in the review we couldn't know if that was due to misuse by a prior user. To be fair, I was advised it was a marketing stock machine but didn't think it would have been that well used - my mistake, not Fein's.
My initial feeling on the ASCM is that it is well made, robust and certainly worth the money. The trigger is very responsive although has slow start-up (if that makes sense). The engineering of the changeable head is just superb and the 4 speed gearbox puts it way ahead of the usual contenders. It takes some getting used to selecting the correct setting but this is a minor learning curve. The balance is spot on and it has a reassuring mass.
If you have any particular questions or you want me to try a particular application, let me know and I'll post the results on here.
