High cutting efficiency: the proprietary heat treatment and triangular cross-section design preserve the flute’s sharp cutting edges, allowing the clinician to reach full working length with less resistance and more control during the procedure. Minimally invasive: has a maximum flute diameter of 1mm and a noncutting tip to minimize transportation and preserve the tooth’s structural integrity. Counter-clockwise flute design, with exceptional strength, superior resistance to failure, and minimal file breakage.
