Scene description
More endfight between the T-850 and the T-X.
The first pic (from official T3 Magazine #2) shows us the T-X grabbing the T-850's throat.
The next two pics are from the promotional The Mirror T3 DVD and show us the T-X grabbing the T-850's throat and face.
The next four pics are from the T3 DVD and show us the T-X grabbing the T-850's throat and face.
The next two pics are from the first T3 trailer, where this deleted part is shown. It's the T-X and her rotary saw at the right. This shot does not appear in the movie. However, my doubt is whether this shot is part of this deleted sequence or from the scene in which the T-X frees herself from the particle accelerator. I choose to include it with this deleted scene, because her rotary saw is too close to her own face, while with the particle accelerator-scene, it should be further from her face.
The first pic on the last row is from the comic and shows how the T-X attacks the T-850 with her rotary saw, the same way it is described in the novelization.
The last two pics show the make-up stage of Arnold Schwarzenegger. The first pic of this show the differences between the 2 stages, the last pic is a larger format of the "stage 7 - added saw cut."

The official T3 novel mentions this part:
The T-xX, her legs sheared off in the wreckage, held on to Connor's ankle with her
right hand and began to inexorable draw him  back under the blast door.
Terminator grabbed her wrist with one hand and her throat with the other in an effort
to drag her away from Connor.
In the effort his shoulder turned away from the blast door that then inched downward,
pinning him and the T-X like a hydraulic press.
The buzz saw morphed from the T-X's left hand, and she drove it into Terminator's chest,
just above his one remaining power cell.
Terminator tightened his grip on her wrist, bending hydraulic joints out of position,
causing her finally to lose her grip on Connor's ankle.
The door was pinning their torsos even more tightly now. Nevertheless the T-X managed
to bring the saw up from Terminator's chest, into  his neck, and then into his chin
and cranial case.
Circuits shorted out and massive dumps of random data no longer under the control of
subroutines cascaded like shivers through his CPU and servos.
(...) 
He released his grip on the T-X, and for a second their optical sensors locked together.
The T-X withdrew the saw and started to crawl the rest of the way under the blast door.
