Which tool is useful for preventing runs or frays when drilling?

A carpet punch is designed to create a clean hole in fabric or carpet, which helps prevent runs or frays when drilling. This tool embeds a small, contained opening that minimizes damage to surrounding materials. In contrast, other tools listed serve different functions: diagonal cutters are primarily used for cutting wire or cable, a compression tool connects coaxial cables using connectors, and a hand line is generally employed for guiding cables or managing materials rather than directly addressing the integrity of materials during drilling. Therefore, the carpet punch is the most suitable choice for ensuring clean and precise drill holes, protecting the edges from fraying.
