The PFERD 44151520 Medium-Hard Felt Polishing Pin is designed for precise polishing tasks, especially when maintaining exact geometric shapes is essential. Its cylindrical shape with a head bore is particularly suitable for peripheral use, while the variant with an end hole (ST-BO) is ideal for face-down applications.
- Hardness and Flexibility: The felt's hardness and flexibility allow for accurate profiling, making it suitable for tools with complex geometries.
- Metal Insert (MS) Version: The MS variant includes metal inserts, enhancing stock removal during pre-polishing with diamond polishing pastes.
