A low cost solution to quickly remove chips and contaminants from grooves, containers and drilled holes, theDeep Hole Vac-u-Gunreplaces dangerous blow guns that can cause chips or debris to fly in all directions. Simply position the Deep Hole Vac-u-Gun over the hole and press the trigger. A small blow tube dislodges and lifts the chips while the large suction tube vacuums them away. The operator is protected from flying debris since all contaminants are contained within the clear suction tube. It is perfect for cleaning holes up to1-1/4"(32mm) diameter at a depth of 18" (457mm). The Deep HoleVac-u-Gunuses less compressed air than an ordinary blow gun since it injects a small amount of compressed air through directed nozzles to produce a vacuum on one end and a high output flow on the other. The amplified output flow is 12 times the air consumption rate.
