• Dual air chamber provides for dust collection and suction to the wall

• Replaceable brush ring provides dust seal for a wide range of bit diameters
• Rubber seal maintains suction on the drilling surface

The HDC250 is a flexible dust collection attachment SDS-max hammers for drilling into concrete with core bits. It is optimized for drilling diameters from 1-1/2 In. to 5 In. but can accommodate up to 6 In. if the brush ring is removed. The attachment features two unique air chambers: one allows the drilling bit to pass through when drilling into the work surface. The second air chamber is designed to maintain suction to the wall during the drilling application. The dust port is designed for Bosch 1-3/8 In. vacuum nozzle but can be used with either 1-1/4 In. or 2 In. vacuum nozzles when used with the appropriate adapter. The system is universal and is designed to connect to a vacuum so that it can be used with any size hammer and can accommodate the full range of core bit diameters and drilling depth.
