Interchangeable teeth for the NA0/1 reamer, for flexible bushings with a diameter of 1.25 mm to 1.75 mm, set of 3 pieces. Three-tooth reamers are used for quick and easy installation of flexible bushings of all types. After inserting all 3 teeth into the center of the bushing and squeezing the lever, the reamer expands the bushing in three directions, increasing its inner diameter. This makes it easy to install the bushing on the cable and then secure it in the desired location after releasing the lever. To facilitate installation, we recommend using the Hellerine lubricant.
