To solve the problem that such a solution as to reduce the quantity of ground powders without using driving of a dust collector or the like is desired since a dust absorption sander which absorbs dust by using a driving source is known but when moving that tool in result grinding work, it becomes heavier than a tool which does not absorb dust or a dust collector is configured to work while being mounted on the shoulder or on a waist belt of a worker but in the case of long-time work, a load may be applied to the worker.

A putty grinding tool for interior finishing is provided which is characterized in that a hook-and-loop fastener is provided on a surface of a base part in a sander equipped with a handle, a brush is configured by including a hook-and loop fastener attachable/detachable to/from the hook-and-loop fastener and planting bristles so as to extend outside around the hook-and-loop fastener, and powders of putty is adsorbed by static electricity generated in the brush.
