Abstract
A grinding tool includes a handle with a driving device for driving a grinding member connected to a shaft extending from the driving device. A cone-shaped recess is defined in a distal end of the shaft and a flexible cone-shaped piece is received in the cone-shaped recess of the shaft. The grinding member has a shank extending through the flexible cone-shaped piece and a retaining cap is mounted to the shank and threadedly mounted to the shaft. The grinding member can be replaced with a grinding wheel and a fender is rotatably mounted to the shaft. A quick release device is connected to two lugs on the C-shaped collar of the fender so that the fender can be conveniently loosened and rotated by operating the quick release device.
