Bosch HDC250 SDS-max Core Bit Dust Collection Attachment

The Bosch HDC250 is an outstanding dust collection attachment designed for SDS-max hammers when drilling into concrete with core bits. It's a versatile tool optimized for drilling diameters ranging from 1.5 inches to 5 inches, and it can even handle up to 6 inches if you remove the brush ring. This attachment has two special air chambers. One allows the drill bit to pass through when you're drilling into the work surface, while the second is crafted to keep suction on the wall during the drilling process. The dust port is made for a Bosch 1.375-inch vacuum nozzle, but with the right adapter, it can work with 1.25-inch or 2-inch vacuum nozzles. It's a universal system that can connect to a vacuum, so it can be used with hammers of any size, accommodating the full range of core bit diameters and drilling depths. What's included? Just one dust collection attachment. Key features are a dual air chamber for efficient dust collection and wall suction, a dust port that fits various nozzle sizes with adapters, a replaceable brush ring for a good dust seal on different bit diameters, and a rubber seal to maintain suction on the drilling surface. Inlet diameter is 1.375 inches, and the max bit diameter is 6 inches.

Using the Bosch HDC250 is quite straightforward. First, connect it to your SDS - max hammer and then to a vacuum cleaner. Make sure to select the right adapter for the vacuum nozzle if needed. When drilling, the dual air chambers will do their job to collect dust and keep suction on the wall. You can adjust the bit diameter according to your needs, but remember, if you want to use a bit larger than 5 inches, you'll need to remove the brush ring. As for maintenance, clean the dust port regularly to ensure good suction. Check the rubber seal and brush ring often, and replace them if they show signs of wear. Always use the appropriate adapter for different nozzle sizes to avoid any suction issues.
