Newly developed penetration file for path finding D finder's. D-shaped cross-section has achieved blade part strength, unprecedented with conventional penetration files.
Obviating excessive cutting and intrusion in the calcified root canals or in the curved root canals. Its ISO .02 standard taper alows for a smooth transition of othe files to complete instrumentation. D Finders have 1.5 times fracture less resistance than other penetration files
