A frantic Bronx model desperately kicked a neighbor's door for help after a brute shoved a "tool" so far up her 12-year-old daughter's nose that its drill bit landed in her eye, witnesses and sources said.

Karizma Dabeny, 31, was allegedly repeatedly stabbed by her daughter's deranged stepdad, Joshua Burnside, 28, at the family's East 173rd Street apartment Wednesday night before the suspect turned on the youngster, sending the badly wounded mom begging for help for her child, the neighbor told The Post.

"She was kicking my door and screaming something like, 'Oh my God! Oh my God!' " the resident, speaking on condition of anonymity, recalled of Dabeny, who sources said had been involved with Burnside.

"It was when the cops got here that she told the cops that she was stabbed," the neighbor said. "And then that her kids were still inside and [the suspect] wouldn't open the door and let her back inside."

The resident said police tried to kick the family's apartment door in but couldn't because it was bolted shut.

"They said that the door had a dead bolt or something that they weren't able to kick in," he said. "And it was only after they repeated their request for [the suspect] to open the door that after a while, he just opened.

"After the cops got him out and got the ambulance to take him away, [Dabeny] said something like, 'Oh, this is what I get for allowing him to come visit his kids' or something like that," the neighbor said. " 'I allow him to come see the kids, and that's what ended up happening.' "

Other neighbors reported earlier that the injured mom was bleeding from her head and had been stabbed in the stomach, with law-enforcement sources telling The Post that the tool used to attack the girl was a "drill bit."

The bit had to be surgically removed from the youngster's eye, sources said.

The wounded girl was rushed to Cohen's Children's Medical Center in Queens and underwent surgery after the attack. Her current condition was not available Sunday.

Burnside, who was identified by sources as the wounded girl's stepfather, was charged with assault, acting in a manner injurious to a child and weapons possession -- with the charges expected to be upgraded to attempted murder.

Authorities said he was hospitalized after the incident and is awaiting arraignment Sunday.
