The Bosch 19DC-7 Dust-Extraction Guard works with the Bosch 1974-8 7 In. angle grinder and can be part of the end-to-end Bosch PRO+GUARD™ Protection System, along with attachments, dust extractor and respiration (to be used as a basic summary; always use products in accordance with the owner's manual and OSHA Rule 1926.1153 Table 1). This can help move users toward compliancy with the OSHA silica dust regulation. The dust guard has a durable foot plate for cut stability. The single-screw depth adjustment lets users make changes quickly and easily, while maintaining the desired depth of cut.
