ABSTRACT:
A flange lock 10 for retaining a disc or blade on a spindle of a power tool and for facilitating removal therefrom, comprising a support member 22 for threadedly engaging a spindle of a power tool, a plurality of cam devices 30 mounted through the support member 22, a pressure plate 44 for applying pressure to a flange of a disc or blade to hold the disc or blade on the power tool, the pressure plate 44 including a cam surface 46 for bearing against the cam devices 30, and a housing for receiving the support member 22, the cam devices 30 and the pressure plate 44 and including means 14, 34 for driving the cam devices 30 between an active position (FIG. 3 ) in which the pressure plate 44 is held spaced from the support member 22 and an inactive position (FIG. 2 ), wherein the flange lock 10 can be partially released to facilitate removal of a disc or blade from the spindle of the power tool by operating the drive means 14, 34 to move the cam devices 30 into their inactive position and thereby allow pressure between the pressure plate 44 and the disc or blade to be reduced. Such a flange lock 10 is particularly useful for use with angle grinders and circular saws which, after use, often have their flange locks extraordinarily tight.
