特徴とするデイスクグラインダ。 A cylindrical body with a disk for holding abrasive paper at the tip,
A lock ball is fitted into the spindle so as to be slidable in the axial direction of the spindle, and a lock ball is provided in a through hole drilled in the cylindrical body so as to be retractable in the centrifugal direction, and the lock ball is pressed in the centripetal direction. A sleeve having a first pressing slope inclined downward at the lower part of the inner peripheral surface is slidably fitted onto the outer periphery of the cylindrical body, and is further engaged with the lock ball pressed in the centripetal direction by the first pressing slope. A second pressing slope for preventing upward rolling is formed downwardly at an appropriate position on the outer peripheral surface of the spindle, and a truncated cone-shaped convex part is provided at the tip of the spindle in a widening shape. A truncated conical concave portion having a similar shape to the truncated conical convex portion is provided at the lower end of the truncated conical convex portion. A disc grinder characterized by holding abrasive paper under pressure with a recess.
