摘要： A sander may include a housing, a motor, a sanding platen, and a two-piece fan. The motor may be disposed within the housing and may include an output shaft. The sanding platen may be driven by the motor for movement relative to the housing. The fan may be driven by the motor and may include a first piece formed from a first material and a second piece formed from a second material. The first piece may include a disk-shaped body having first and second opposite sides. The first side may include a plurality of first blades extending therefrom. The second side may include a plurality of second blades extending therefrom and a recess formed therein. The second piece may be received in the recess and may include a counterweight boss formed thereon.

摘要： A power tool having one or more sound damping members which reduce sound and/or vibration from one or more parts of a power tool. The sound damping member can reduce sound and/or vibration from static or dynamic parts of a power tool. The sound damping member can reduce noise and/or vibration from one or more rotating or moving parts of a power tool and its housing or internal structure. Methods, means, controls, systems and practices for reducing or eliminating undesired sound from a power tool are disclosed.
