A portable abrading cabinet device is provided for use in a recycling abrasive blasting system. The cabinet device includes a cup-shaped housing affording an inner blasting chamber. The forward open end of the housing has a peripheral resilient seal to provide airtight engagement with the surface to be abraded. The housing has an inlet aperture for the barrel of a sand blasting gun which delivers rapidly moving abrasive material to the surface to be worked. A funnel-shaped exhaust means in the housing terminates in a fitting which detachably receives a conduit connected to accommodate an external source of vacuum so that spent abrasive and debris may be removed from the inner blasting chamber of the cabinet housing. A transparent window member in the housing permits an operator to observe the abrading operation, the window member being partially shielded by a pair of deflectors which redirect ricocheting abrasive and debris within the cabinet housing. To further aid the observation of the operation, illuminating means are provided within the cabinet. The abrasive is introduced into, and recycled from, the cabinet housing by an appropriate external blasting system.
