Compact, cordless motor with a built-in apex locator. Used for achieving apical patency and creating a glide path with the new Optimum Glide Path (OGP) function. Responsive handpiece allows subtle and delicate manipulation of the file, facilitating faster and safer treatment, even in difficult cases involving constricted or extremely curved canals. Rotary files sized as small as #10 may be used. Depending on the file load, the motor alternates between forward and reverse rotation incrementally until the torsion is released and then resumes in the cutting direction. 1-year warranty.
