New Mafell DDF 40 Duo Doweller

The Timberwolf web site has excellent DDF40 videos. The DDF40 videos I found on YouTube are not English and rather crude.

For reference, I own both Domino machines and the DDF40. The 500 gets the most use followed by the DDF40 followed by the 700.

The 500 is far quicker for most applications using the narrow/wide opposing settings. The DDF40 excels in applications requiring extreme accuracy. Also, I can place two dowels in a space too narrow for two Domino tenons.

I would put the DDF40 a little ahead of the Domino in build quality but not in any way that affects real usage. The DDF40 kit has a number of attachments that greatly enhance its usage, primarily for spacing holes.

The DDF40 uses pins and not flappers for locators. Seems to be a superior design. I find buying metric dowels difficult. Most sources sell only extremely large minimum orders like 5 thousand. I ordered some 6mm dowels on Amazon that came from China. They were undersized. Amazon refunded my money.

The DDF40 requires a lot more force to drill the holes than a Domino needs to cut even a large mortise. This worried me, but Timberwolf staff assured me this was normal.

The fence on the DDF40 seems superior to that of the Domino machines. It’s rack & pinion adjustment is very accurate. I was using the DDF40 on an 8 sided box. The 22.5 degree detent was spot on.

In summary, I really don’t see the DDF40 and the Dominos being direct competitors. The machines overlap a little in application, but each has a wide range of standout usage.

Got me the DDF 40 yesterday.



Very well built unit for sure and I look forward to using it tomorrow or perhaps saturday on a project. Got the kit with most, if not all the add ons including the template adapter and the side extension. A colleague has the template rails so I won't get any myself.

It is down to 800 rpm from the previous G model (18000!!!) and the P (13500) but 8000 rpm is still very fast drilling and I think the bits might last longer too. Initial thoughts are: very well made, bulkier than the DD40G but overall good balance.

Will see how it operates during the next couple of days, it will give the Domino a run for the money for sure!
 
Does anyone know of a particular plug it in speed controller that works with the electronics of the duo doweller DD 40 P?
13500 rpm is way too fast for Australian hardwoods. Mafell recommend pushing the tool harder to slow it down. In reality you cannot accurately bully a 1000 w doweller driving 2 times 12mm bits.
