The Mirka® Roundy is ergonomically designed to fit into the palm of the hand and is suitable for multiple operations from paint stripping to lacquer & paint sanding. Grip and 34 dust extraction holes makes the Roundy a versatile and practical hand block for use with both Abranet® grip abrasives and 15-hole 150mm grip discs, that can wrap around its sides to assist the user in reaching corners and other hard to reach areas that require sanding. The Roundy hand block fits to a 20 mm x 4 m hose.
