Developed to reduce dust formation. The reduced dust formation makes your sanding work easier, cleaner and safer. The PRO Dust Extraction Hood for small angle grinders catches the dust when you need to remove paint, varnish or adhesive from wood, fibreglass and mortar. When sanding with fibre discs or carbide sanding heads, there is less dust in the air thanks to the PRO Dust Extraction Hood. It has a brush ring that ensures that most of the dust is removed during sanding. The extraction bonnet fits all small angle grinders and has an improved metal interface that allows you to attach it securely to your power tool. Attaching a hoover hose is also easier - simply click it into place with the Click and Clean interface.
