Power tool air flow

A power tool comprising:

• a drive housing comprising an air inlet and an air outlet;
• an assembly movably mounted within the drive housing, wherein the assembly comprises a motor and an air flow passage;
• a fan configured to generate airflow from the air inlet to the air outlet;
• and
• a divider configured to divide the drive housing into a first internal section upstream of the motor and a second internal section downstream of the motor, wherein the first internal section comprises the air inlet and the second internal section comprises the air outlet, the first internal section and second internal section fluidly linked by the air flow passage, wherein the divider substantially reduces or prevents airflow between the first and second internal sections except through the air flow passage, and wherein at least part of the divider moves with the assembly.
