Claims

[Scope of utility model registration request]

An angle glider having a grinder body supported so as to be tiltable, and a grinding wheel provided at the tip of the grinder body and driven to rotate, the rotational axis of the grinding wheel being substantially perpendicular to the axis of the grinder body; a pressing means for tilting the grinder and feeding the grinding wheel toward the inner surface of the hole;
A hole internal surface polishing device characterized in that the axis of the grinder body and the center line of the hole are offset so that they do not intersect.
