The Dust Collection Attachment works with most Bosch 4 1/2" and 5" small angle grinders. The attachment can be part of the end-to-end Bosch PRO+GUARD™ Protection System, along with attachments, dust extractor and respiration protection. The dust attachment has a single-screw depth adjustment to adjust it to the desired depth of cut. It has a large, durable foot plate, which greatly increases stability for clean, accurate cuts.
