A portable lightweight drill assembly is mounted against one side of a sheet of flat glass having a hole or crack to be repaired; the drill shaft extends through the hole or crack to mount cutters on both sides; the cutters are spring biased against the glass to exert equal cutting force and simultaneously rotatable with the drill shaft to cut the hole from both sides to a diameter larger than the hole to be repaired, for insertion of a glass repair plug.
