Abstract
An abrasive wheel and drive spindle combination. The spindle is releasably engaged with the abrasive wheel by inserting a threaded end portion of the spindle through an opening in an inner flange of the abrasive wheel and rotating the spindle in a first direction to engaging it with a thread around a central opening in an outer flange of the abrasive wheel. Upon such engagement a collar on the spindle enters and is pressed into a socket coaxially centered in the inner flange to coaxially and releasably lock the abrasive wheel to the spindle so that further rotation of the spindle in the first direction rotates the wheel, and the flanges are held together during use of the wheel.
