OK, I may have missed something really obvious, but what is the difference between the C18 and the T18+3 (apart from the shape)? A couple of the torque figures seem to be slightly different - and what is the '+3' bit all about?
When Festool introduced the T12+3 and T15+3 they were one of the few brushless drills around because the technology was all very new . A brushless motor is more powerful than a conventional brushed motor and this is why they used the +3, to indicate that their drill was as strong as any other drill from a 3 volt higher class. So the Festool T12+3 would compare to a 15 volt drill, and the Festool T15+3 to an 18 volt drill.
This idea is outdated now, and they dropped the name with the C15/C18 drills.
You're correct about the ergonomics though, that's the only real difference between a T and a C drill.
OK, thanks. The additional chuck sets are available for both so it wasn't going to be that. There is a difference in the stated torques - 27/40 for the C18 and 35/50 for the T18 - which still intrigues me.
One apparent difference in these two drills confuses me. On page 120 of the 2016 USA catalog, It shows the C 18 Plus and T 18 Plus sets are both $495, but the t 18 Plus set also includes the eccentric chuck, so I assume that means the C 18 Plus set does not. Is that correct?
There is no difference in price and scope of delivery between C18 and T18.
Both T18 and C18 “Plus versions” include 2 batteries and charger. Both “T18 and C18 Full Set versions” include in addition to the plus version an eccentric-chuck and right-angle chuck.
