Looks like I was wrong, the bit retaining portion is too shallow for a Centrotec bit. That's a bummer if true.

Maybe something was wrong with my tool? I was screwing a pair of 3/4" pine boards to the bottom of 2x8 joists in the basement using 2.5" #9 GRK screws and Ti15 couldn't do it. I had 15v 3.0 Ah Li-Ion battery installed. A 12v Hilti had no problem finishing the job.
And the failure to drive fasteners was not the only instance. I loved the electronic clutch, so it was sad to see Ti15 go, but it's performance was absolutely abysmal. I got a C15 a few months back and really enjoying it. It got loads more power than my old Ti15.
