Microduct De-Burring Tools are designed to make chamfering the inside of microducts simple, helping to ensure pushing and pulling are smooth operations. It is used after a cut has been made to the microduct and prior to inserting a cut microduct into a coupler. The purpose of the de-burring tool is to form a conical shape on the inside surface of the microduct that, after insertion into a coupler, allows the fiber to glide between microducts with ease.
