If no dust extraction is available for drilling or grinding, running a water hose onto the surface or holding a vacuum up to the tool will keep dust down. 2. Use a drill dust attachment by turning the vacuum on and sticking the attachment to the surface. The suction from the vacuum should hold it in place. 3. Drill in the allotted area through the dust attachment. 4. In areas where a vacuum can’t be used, use a dust attachment with a built in HEPA filter. 5. Attach a dust collector drill bit to the vacuum and the dust should go straight through the bit itself. 6. Use a grinder dust attachment by connecting the attachment to the grinder. The vacuum can be connected to the attachment.
