Zusammenfassung:	A grinder wheel coupling apparatus is provided to reduce costs by eliminating the necessity of manufacturing a grinder having a spindle with a special shape. A grinder wheel coupling apparatus(300) includes a first main body(310) and a second main body(330). The first main body has one end with an inner surface on which a wheel joint hole(312) is formed and the other end with an inner surface on which a spindle joint hole is formed and an outer surface on which a first joint bolt is formed. The second main body has one end with an inner surface on which a first joint hole(332) is formed and the other end with a spindle joint hole(334). The grinder wheel coupling apparatus further includes a ball passage(316) formed on the outer surface of the first main body; a chucking ball(318) inserted into the ball passage; a joint member(320) having one end with a ball locking part(324) and the other end with a second joint hole(326); a chucking spring(340) inserted between the second joint hole and the joint member; and a wheel discharge spring arranged in the wheel joint hole.
