Plate-shaped oscillating tool for e.g. sawing joint material, has working surface for grinding or polishing purpose, where quotient of working surface of tool and rated power of drive motor is of specific value

摘要

The tool (24) has a work spindle (14) driven by a drive motor about a longitudinal axis (22). A working surface is utilized for grinding or polishing purpose. A quotient of the surface of the tool and rated power of the motor is about 40 square millimeters per watt. A driving element is made of steel i.e. hardened steel. A back element is made of aluminum, magnesium alloy, plastic or composite material. A carrier element is made of an elastomeric material. An adhesive element is made of Velcro(RTM: hook and loop fastener) material.
