A sander with angular adjustability includes a main body, a workbench, a grinding shaft, a driver, and an angle-adjusting device. The workbench is mounted on a top of the main body. The grinding shaft is rotatably installed on the main body and exposed outside the workbench. The driver is installed in the main body, for driving the grinding shaft to rotate. The angle-adjusting device is configured to be in transmissive connection with the driver. The angle-adjusting device is configured to be switched and operate between a locked position and a released position. In the released position, the grinding shaft has its grinding angle adjustable with respect to the workbench, and in the locked position, the grinding shaft is held at a grinding position by the angle-adjusting device. Thereby, operation of the sander is angularly adjustable to fit different wooden workpieces.
