The FTS3 will provide precise cuts through Ø3 mm and Ø3.8 mm furcation tubing. Simply set the depth of the dual cutting blades before placing the cutting tool around the fiber. Then spin the tool around the fiber several times. This results in two precise cuts through the tubing. The furcation tubing between the two cuts can then be removed by using the blade at the end of the FTS3 to make a precise cut through the tubing along the length of the fiber. Each FTS3 also comes with a blade that has a rounded tip. Long cuts along the length of the fiber can be made through the furcation tubing by swapping the blade at the end of the FTS3 with the rounded blade. Simply place the fiber in the end V-grove, press the blade through the furcation tubing, and then draw the fiber through the tool. Replacement blades (FTS3B) are available for the FTS3 stripping tool. Each FTS3B contains three straight blades plus the round tipped blade.
