K Engine and XT Files by Sybron Endo are triple-fluted and asymmetrically designed for fast, efficient cuts. These nickel-titanium files have unparalleled debris removal, with an increased helical angle; this allows for continuous instrumentation and a much lower risk of clogged flutes. Further, calibration rings on the side of the file make depth determination easy. There are .02, .04, .06, .08, .10, and .12 tapers available.

The efficient design of Sybron Endo NiTi is comprised of three radial lands; one has a positive rake angle for active K3 cutting action and stabilizes the instrument. Another has a reduced radial land with wide blade support for peripheral strength to resist torsion and rotary stresses. The third land relief greatly reduces friction on the canal wall, with the least surface contact.
