Abstract
A device for dissipating heat from a rotary power tool is disclosed. The rotary power tool comprises a hollow disc housing. On the top planar surface of the hollow disc housing, a plurality of hollow bolts traverse the surface of the hollow disc housing into the interior of the hollow disc housing. In the interior of the hollow disc housing, the hollow bolts create a substantially angled plane relative to the top planar surface of the hollow disc housing. The hollow disc housing encloses a heatsink. When the heatsink spins, it creates a vacuum, thereby drawing exterior air through the hollow bolts. The angled plane created by the hollow bolts directs the flow of air through the heatsink. The combination of the heatsink and the directed air flow serves to cool the rotary power tool and prevent overheating.
