Abstract
A power tool including a primary housing and a motor assembly connectable to a cutting tool. The motor assembly is configured to drive the cutting tool. A secondary housing is mounted within the primary housing. At least one first dampening system is coupled between the primary housing and the motor assembly. At least one second dampening system is coupled between the primary housing and the secondary housing. The at least one first dampening system and the at least one second dampening system are configured to reduce vibrations in the secondary housing generated by the motor assembly.
