<p>Tobi's Intangibility works by moving any part of his body that is in contact with anything else into the Kamui Dimension. Regardless of weather it is manual or automatic, when he has his intangibility active, his body is split between the 2 dimensions, the main and Kamui dimensions. Between them, his body is 100% tangible, however, almost no one can go into the Kamui dimension and actually see the parts of his body moved there. Kakashi was in a position to do so however at the time of the scene in the question. As shown, his torso has been moved to the kamui dimention in order to become intangible to Naruto's attack. Kakashi was easily able to attack it then, since it can't be intangible in both dimensions at the same time. His body is never actually intangible, it's just moved to a place where no one in the main dimension can reach it.</p>

<p>A simple explanation would be that he does not have control over which parts of his body is able to interact with the real world and which parts would teleport to the dimension. When the jutsu is activated, it simply teleports any part of his body (and the things in contact with his body at the moment of activation) that comes in contact with another object. Otherwise he would have to focus a lot on using this jutsu to be exact or he would just have to teleport chunks of his body that he assumes will get hit.</p>

<p>well what most of us are missing is that kakashi and tobi has the same eyes i.e. Both eyes are Obito's so actually both of his eyes are connected to the same time and space.Hence even when tobi uses his Space-time ninjutsu ,kakashi uses his kamui(Same Space time justs) to travel that alternate time-space and touch tobi or attack tobi</p>

He doesn't become intangible, he just transports parts of his body to Kmui's dimension. So the part he transports to that dimension are vulnerable to someone already in that dimension, like Kakashi. Thus he can't become intangible in the alternate dimension because he uses it to become intangible

yeah, but the rest of the body in the "real" world, should be able to hit and attack as it is not being intangible and able to hold real world ninja tool.

I think Tobi's technique allows him to allow other objects to pass through his body by transporting parts of his body that overlaps with the parts of the object of this dimension. This logic would answer your question I think. Or am I missing something?

@MeharoofNajeeb : i wanted to know why his attacks (body + ninja tools) also pass through the targets if he only transports his own body parts (under attack) ?

**Is there any explanation or any theory on this matter?** Yes.

Kakashi discovers Obito's weakness, to which he explains how [Obito's](http://naruto.wikia.com/wiki/Obito_Uchiha) space-time justu works in the manga chapter 597, and utilizes it against him.

> Although Kakashi cannot use Kamui against Obito directly, he can use his own access to the other dimension to negate the advantages Obito makes use of: by teleporting attacks or allies to the other dimension at the same moment that Obito's body resides there for defence, he can be attacked successfully

Kakashi states that attacks "passing through" is Obito is incorrect - Obito sends his body into a different dimension; where he is completely tangible.

Kakashi begins to understand how this justu works when he sends a kunai into the other dimension using his own Kumai ability at the same moment Obito teleports his head to dodge an attack from Naruto.
