Abstract
A protective device is provided that covers a drill chuck to protect it from dust or debris that may be released when a material is being drilled. The protective device has a mixed gasket comprising two sheets with fins that in their central part have independent movement where both are perforated (female type), while the other sheet contains caps (males) that are joined for better manufacturing, wherein said males are long so that they pierce the female holes and embed themselves in a base that is located directly in the protective device, allowing its adequate fastening.
