Interchangeable teeth for the NA8/10 reamer, for flexible sleeves with a diameter of 12.0 mm to 17.0 mm, set - 3 pieces. Three-pronged reamers are used for quick and easy application of flexible sleeves of all types. After inserting all 3 teeth into the center of the sleeve and squeezing the lever, the reamer stretches the sleeve in three directions, increasing its inner diameter. This makes it easy to put the sleeve on the wire and after releasing the lever, place it in the desired location. To facilitate installation, we recommend using the Hellerine lubricant.
