The Evolution precision file sander is a versatile, powerful and compact tool, ideal for sanding, filing, as well as sharpening tools and blades. Ideal for use in tight gaps, such as cleaning out door locks, plus handy at removing rust and excess weld. Features an adjustable sanding arm, which allows the operator to keep their hand/wrist in a comfortable position and instead alter the angle of the sanding arm to suit the job. Variable speed control (300 - 1700rpm) provides optimum control and finishing on a number of surfaces and materials, including wood, metal, plastic, ceramics and masonry. Three sanding belts are included, ideal for wood, metal and plastics. The coarser paper grade removes the unwanted material faster and with less effort.
