Black & Decker's really useful Power File is a great power tool for taking care of all kinds of sanding jobs, especially where access is awkward and those difficult to reach areas. Fitted with a 13mm wide belt and a 120mm long arm, this powerfile is particularly useful for sanding internal apertures and mortises. It is also handy for removing rust spots and corrosion on metal surfaces. The Black & Decker KA900E Power File is perfect for shaping, filing and sharpening too.
