Our Dry Coring Dust Extraction Attachment allows you to be OSHA compliant when drilling with larger diameter rotary hammer bits or core bits. The drill dust shroud works with our MILWAUKEE® 8-Gallon Dust Extractor (8960-20) to eliminate dust when you are drilling or dry coring with bits up to 6" in diameter. The vacuum suction allows the dust shroud attachment to stick to the wall or ground allowing you to easily and accurately drilling and coring.
