An endless abrasive belt of the type including one or more sections of backing material supporting an abrasive coating and having adjacent end portions overlapped to form joints extending obliquely of a direction of belt travel is characterized by the abrasive coating on an inner one of the overlapped end portions being removed over the longitudinal extent of the overlapping and the abrasive coating on an outer one of the overlapped end portions being removed only over a longitudinal extent in a range of about 30 to 80 percent of the overlapped distance.
