An Adaptive Dust Shield Device having Zero Standoff Capability for rotary grinders having a bearing housing and an axial groove around the bearing housing. The dust shield has a cover molded from a single shot. The cover has a plurality of upstanding flexible fingers, in multiples of four, which extend upward from the cover. A door is formed in one side of the dust shield cover to allow the user to use the dust shield in zero clearance situations. The flexible fingers have a defined width and are separated apart from each other by a space between each one. The width of the space is less than the defined width of the flexible fingers. A stretchable fitting ring fits onto the bearing housing of the grinder and under the flexible fingers. The flexible fingers are secured onto the stretchable fitting ring by a securing fastener. There are a plurality of vent holes formed in the top wall that are selectively pluggable with plug elements.
