BUT what im saying is the adpater is NOT needed its only NEEDED because festool made it so! Their was no need for it. The angle chuck COULD of been mounted directly but Festool designed it so it cant because they clearly didnt see another way of turning the impact off but they where wrong very wrong.
Dont know if you have seen the adapter in person but imagine if you was holding the T15 drill and got a saw and cut of the end of the T15 then modified the side you cut so it would fit onto the Ti15 well that is what festool have done. They just made a different chuck system on the Ti15 but then to make it work with the Festool SYSTEM they made the adapter to make it like a T15.
They should of kept it like the T15 and just like I keep saying is extended the internal pin inside the Ti15 OR extended the ends on all the chucks like I did in the video! These would ALL still work on the T15 because any one who owns a T15 have a look down yours you will see T15 drill has a hole inside which will take the extended pins! So Festool could make all new angle chucks etc but that would wind people up who already own them so it would be best to drill out a centrotec specially for the impact drill.
Any way I have mentioned my solution many times now! FESTOOL READ IT! ADMIT TO A STUPID DESIGN! GET BACK TO THE DRAWING BOARD! OR CONTACT ME and give me a valid reason why the adapter is needed
The TI 15 was specifically designed to prevent someone from installing a standard right-angle or offset chuck to the drill. That's because you cannot hammer on a gearset that was not designed for the hammer action. It will fracture the gear teeth. Any auto mechanic will tell you that you can't use a standard socket on an impact wrench because you will shatter the socket. A few years ago I borrowed a standard universal joint (swivel adapter) from a neighbor and used it with my impact wrench on the car. Even though I knew the risk, it was shattered in less than 5 seconds. (When I bought a replacement for him, I also purchased an impact-grade universal for myself.)
The TI 15 adapter disengages the hammer that causes the impact action.
You have indicated that Festool could have accomplished the same task by lengthening the pin inside the TI 15 so that a standard chuck would disengage the hammer. While that is true, you are forgetting about the very critical negative consequence this would have in impact mode, which is what the drill was intended for. With that pin lengthened, in order to have impact chucks
not disable the hammer, their contact surface in the hex would have to be shortened, or hollowed. That will weaken the interface during an operation where the interface actually needs to be at its strongest. You're missing the forest for the trees.
The TI 15 is an impact driver, first and foremost, but has the added benefit of permitting drill-mode action without impact hammering. The intention of that is so that you can pilot drill the holes you are about to drive a large screw into without using a separate drill. Most drill bits are not designed for impact mode. Spade bits being the most susceptible.
By the way, I'm surprised no one has pointed this out yet, but in your video comparing the TI 15 and T15 driving long screws in non-impact mode, you have the T15 in 1st gear. The TI 15 does not have this added planetary gearset that engages when the T15 is in 1st gear. That's because the TI 15 is not intended to have high-torque when not in hammer mode. The differences in torque will be less pronounced if you didn't engage the extra gearset of the T15.
By their very design, impact drivers and impact wrenches do not have high torque in the rotational component of their action. If they did, they would rip your arm off and completely defeat the purpose of the hammering action. Instead of a constant high-torque action, they use sort-duration impulse force to achieve the power in their rotational action.
Edit: Oh, you posted a new video while I was typing. This is actually demonstrated quite well in your newest video.
