ABSTRACT:
A coupling flange for use on a power tool such as a portable grinder for transferring torque loads from the motor-driven spindle of the tool to a tool element subassembly such as an abrasive disc subassembly. The coupling flange is designed to accommodate and be usable with both hubbed and non-hubbed abrasive disc subassemblies. The coupling flange is adapted to be installed onto the spindle of the tool and comprises a first contact surface for frictionally engaging the spindle, and at least two radially spaced annular drive surfaces. The first drive surface is adapted to frictionally engage the backing flange of a hubbed-type of abrasive disc subassembly and the second drive surface is adapted to frictionally engage the backside of the abrasive disc of a non-hubbed type of abrasive disc subassembly.
