Dust guard cap for a hand-held drilling device |
摘要 |
A dust guard cap for the tool holder in a hand-held drilling device is formed of a casing secured on the tool holder and a cover member mounted on and extending across one end of the casing. The cover member forms an opening through which a tool can be inserted into the tool holder. Attached to the cover member and extending inwardly from the through opening is a resilient sleeve-like torus which forms a seal around the tool. An outwardly projecting bead is formed on the inner end of the torus and bears against the casing.
