Abstract

The present disclosure provides a grinding cup for detachable connection to the output drive shaft of a grinding machine for grinding buttons on drill bits or cutters, said grinding cup having top and bottom surfaces and consisting of a lower grinding section and an upper body section co-axial with said grinding section to form said grinding cup with a centrally disposed recess formed in the bottom surface of the grinding section having the desired profile for the button to be ground; the improvementsaid body section having a centrally disposed upright drive section formed on the top surface of the grinding cup, said drive section shaped and sized to both driveably engage within a corresponding recess at end of the output drive shaft of said grinding machine and provide axial and radial support and retaining means for detachably connecting the grinding cup to the output drive shaft of the grinding machine wherein said drive section has a non-circular cross section and is tapered from the top surface of the grinding cup to the free end of the drive section.
