Abstract
The handheld power tool (1) has a tool socket (2) to hold a tool (4) on a working axis (11) as well as a striking mechanism (6) with a striker (14) that is moved periodically back and forth along the working axis (11). The striking mechanism (6) is secured in a tool housing (20). A handle (9) is attached to the tool housing (20) by means of a damper (21). The damper (21) has a surface (25) that is joined to the tool housing (20) as well as a surface (24) that is joined to the handle. A block (27) made of a porous elastomer is arranged so as to be in contact with the tool surface (25) and with the handle surface (26). An air-filled cavity (30) is provided inside the block (27) between the tool surface (25) and the handle surface (24).
