The new HDC200 and HDC250 are designed for drilling applications for the larger SDS-max and spline hammers. These flexible systems are universal in nature in that they are not tool specific. These units simply connect directly to a Bosch dust extractor (vacuum), and the air suction through one of the two specially designed air chambers sucks the unit to the wall. The second air chamber allows the drilling bit to pass through for the actual dust collection process.
• These units feature the integrated 1-3/8-in. dust port, which fits the Bosch vacuum nozzle
• Dust port adaptors (sold separately) are also available to convert the dust port to either 1-1/4- or 2-in. vacuum nozzles
• The HDC200 is designed for a maximum bit diameter of 2-1/2 in. However, it is optimized for drilling diameters from 5/8 in. to 1-3/8 in.
• The replaceable brush ring is flexible enough to provide the proper air seal around these different bit diameters
• For diameters from 1-3/8 in. up to 2-1/2 in., the brush ring must be removed
• The HDC250 is designed for larger (core bit) diameters up to 6 in., although it is optimized for diameters from 1-1/2 in. up to 5 in.
• The HDC250 also features a replaceable brush ring that provides the proper air seal around these different bit diameters
• For diameters greater than 5 in., the brush ring must be removed
