Well done JMB. Watch your back for some german engineers...

While I admire Festool's ambition to creat a dual purpose tool, I think they should have just gone ahead and made the best impact driver they could - 18 V. and forgotten about the combo unit altogether. You would think that much of their existing customer base already has a Festool drill and are just looking for an impact driver to go with it, use the same batteries, etc. Although they would still look for a differentiator - if only they could come out with a powerful impact driver that would work at right angles and offset as well like their drills do. I'll stick with my C15 and buy a single purpose impact driver if the need arises.

So those the impact drill has different gears for low/high speed?

Protool seem to do a much better job - they should just make 'em green!

That adapter is really something they need to re work the design.

Hi
 First post so hi to all. Lurked for a while and have used Festool for a long time in my trade work.
The TI15 adapter works like this so that the other chucks can be used, right angle etc. For small screw and fixings this system works well. Driving in a single fixing is a bit harsh on both machines, battery usage needs to be taken in to account as well, one may do a 100 the other 130 so which is the quicker machine?

I find it strange as well that the large adaptor only pushes a pin inside the driveshaft. Wouldn't it be smaller and easier if festool had made a centrotec adapter that was a little shorter so when the drillbit or driver is received it travels deeper inside and disables the impact?! They could make it a different colour similar to the different sanding pads- grey for example instead of green.

Ok JMB it's interesting that you figured out how to disable the impact but if you want to really impress everyone you should try and do what festool should have done in the first place. Enable the impact while using the right angle attachment!!

No really can you?

has anyone looked at the ekat system to see whats inide the adapter.
the ekat site wont stay open for me

 What Dogwood wants to achieve, and what I think is usefull to, is to mount the angle chuck with impact mode ON. If it's possible to mount the rightangle chuck directly to the drill, without the adapter, and the impact function still works, then off course there's no need for any modification.
My understanding was that the right angle chuck couldn't be mounted without the adapter.  (So apart from turning the impact off, it ALSO enables the mounting of the angled chuck, which is the function that will remain after the modification)
My last comment suggested that maybe the internals of the right angle chuck might not be heavy duty enough to handle the extra force of the impact.

Wow the video really shows what you mean! This is a HUGE disappointment.

 When the TI15 first came out many people said how silly it was that it converted into a drill and that most people have a separate impact and drill anyways. I felt it was similar to people that say the festool attachments are overrated such as the right angle and how one could just buy a devoted right angle drill. I figured if it was a Festool impact then it would be great and if you needed another drill it could do that too.

Well not only does it have a pointlessly large impact-disabling adaptor such as JMB showed but it also looks to have the same power as a cxs!!

I was originally wondering why it wasn't a TI18 in the first place. I mean the biggest advantage of an impact is the high torque with little or no torque response on the user which is important when driving large fastners not small ones.

AND (just to vent a little more) not having the right angle attachment work with impact?! if the right angle isnt up to the task theres a solution- make one that is. When so many companies make affordable right angle drivers for their cordless platforms its pretty lame Festool cant...

Just to address a reoccurring comment in this thread -- The adapter that overrides the impact is for drilling purposes. If you're driving screws, you should generally use the impact feature with the TI 15. For right angle driving, there's enough torque to drive a common sized screw.

I just drilled holes with the 15-35mm diameter Zobo bits into a Douglas Fir 4x4. Granted, not hardwood. I stalled out a little with the 35mm after about an 1" deep or so. That's way more than a pilot hole IMO.

Mike, the TI 15 was primarily designed as an impact driver. It's convenient that it has the capability that it can do other tasks, but there is a slight compromise that comes with that versatility. It's got a very high RPM, 3900 if I recall correctly, but lower torque because of it. EDIT: I felt it was important to say that I have personally tested it against many competitors top-of-the-line impacts and saw no appreciable difference in impact driving performance between any of them, including the TI 15. The advantage of the TI 15 is that it's more than just an impact.

So, to answer your question, the C-series and T-series drills are going to offer more torque. But the TI 15 will offer faster drilling and driving speeds in most applications. So it's the question of speed or torque to choose the best one for your needs. It some cases, it will be the combination of both.

The TI 15 will, as far as I know, be offered in the US/Canada as just a bare tool without the charger and batteries (or maybe one battery). I don't remember the scope of delivery right off hand. As a bare tool, it will come in a systainer that will accommodate the TI 15 and another Festool drill, as shown below.

I think most TI 15 buyers will also have or get a standard Festool drill to complement it, probably in the form of this bare tool configuration. It really depends on your specific needs.

ETA is this fall.  You can check on ETA for new tools here.

Has the price for the bare tool been published yet?
