Portable Drilling Machine PDF 17: Advantages and Disadvantages

Hand tools and portable power-driven tools with percussive action for supporting another primary function, e.g. cutting, are classified in the relevant places for the primary function. For example, hand-held cutting tools employing percussive action for cutting, such as axes or hatchets, are classified in B26B 23/00. However, impact drilling machines with percussive action for supporting the drilling operation are classified in B25D 11/00, B25D 16/00 and/or B25D 17/00.

Hand tools and portable power-driven tools with percussive action which are specially adapted or used for a particular purpose are classified in the relevant application-oriented places. For example, hand tools especially for nailing or stapling are classified in subclass B25C, e.g. nail punches. Pick hammers and chisels especially for mining or quarrying are classified in E21C 37/24 and E21C 37/26.
