The 5319-DE dry core drilling dust extraction attachment allows users to be OSHA compliant when drilling with larger diameter rotary hammer bits or core bits. The attachment works with the Milwaukee 8 Gallon dust extractor (8960-20) to eliminate dust when drilling or dry coring with bits up to 6 in. in diameter. The vacuum suction allows the attachment to stick to the wall or ground for easy and accurate drilling/coring.
