- recommended work procedure - screw the crown directly onto the thread of the angle grinder head, tighten firmly. Start to circle the desired hole at an angle of 45°, the crown and the speed of the grinder will immediately secure the attachment in the desired place, slowly straighten the direction of the circle to a vertical position with evenly created pressure.
