The HDC250 features a dual air chamber design that optimizes dust collection while maintaining constant suction to the work surface. This universal attachment accommodates core bit diameters from 1-1/2 in. to 6 in., making it compatible with a wide range of rotary hammers and vacuum sizes.

• Dual air chamber technology provides efficient dust collection and maintains strong suction to the wall during drilling.
• Universal compatibility works with both SDS-Max and SDS-Plus rotary hammers for versatile job site use.
• Adjustable diameter support accommodates core bits from 1-1/2 in. to 5 in., or up to 6 in. with the brush ring removed.
• Replaceable brush ring ensures a tight dust seal across a wide range of bit diameters.
• Flexible vacuum connectivity fits 1-3/8 in. nozzles natively, with adapter compatibility for 1-1/4 in. and 2 in. nozzles.
• Rubber seal design maintains consistent suction on the drilling surface for cleaner operation.
