Four piece power tool adaptor set is engineered to connect a wide range of major power tool brands to your home shop vacuum for recovery of the debris and dust generated during the use of the power tool keeping you and your shop clean while protecting you from airborne particulate that can harm your health. The adaptors are designed to be versatile with the most unique and tool industry typical connections. The inner collar with durable acetyl clip connects directly to most brands of dry wall sanders and other tools generating high volumes of dust or having large debris profiles. A bayonet fitting with a 25mm (1″) soft TPE moulded fitting is perfect for small power tool connections. The smooth 360 degree swivel rotation of the bayonet prevents the hose from kinking or resisting free movement of the power tool Changing from the 25mm fitting to a 38mm (1.5″) soft TPE fitting popular on many chop saws and routers takes only a second using the quick clip system. Further adaptors included in this four piece set are 19mm (0.75″) and 32mm (1.25″) fitting additional brands of tools and shrouds. Finally an air relief is designed into the bayonet fitting to allow adjustment of the air stream at the tool as necessary to prevent tools sealing to the work surface.
