The BOSCH HDC250 SDS-max® Core Bit Dust Collection Attachment is the smart, no-fuss solution for keeping concrete dust under control during core drilling. Built for SDS-max® hammers, it’s ideal for professionals and serious DIYers who want a cleaner, more efficient worksite.

Key Features & Design

• Compatibility: Flexible dust collection attachment designed for SDS-max® hammers when drilling into concrete with core bits.
• Drilling diameter range: 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.
• Dual air chambers: One air chamber allows the drilling bit to pass through when drilling into the work surface; the second air chamber maintains suction to the wall during the drilling application.
• Dust port compatibility: Dust port 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.
• Universal system: Connects to a vacuum so it can be used with any size hammer and supports the full range of core bit diameters and drilling depth.
• Seal and dust control: Replaceable brush ring provides a dust seal for a wide range of bit diameters; rubber seal maintains suction on the drilling surface.

With its dual air chambers and adaptable dust port, the HDC250 helps you keep the dust where it belongs—inside your vacuum system—so you can see your drill bits, not the mess. Durable, versatile, and a bit cheeky about messes, it’s a must-have for anyone serious about concrete core drilling.
