Drill grinder apparatus

(Amendments Included) SUBJECT of the Invention It is a drill grinder apparatus which can make a hole in a raw material perpendicularly|vertically correctly without bluring hole-punching in right-left back-front， When vacating a hole for a raw material by the hand-drill machine and a perpendicular|vertical drill machine and vacating a hole for a raw material with a drill， the drill grinder apparatus which raises the precision of a finishing grinding and carries out final polishing of the inner wall of a hole is provided. PROBLEM to be solved When drilling|piercing in a normal position by a hand-drill machine， 2 A of horizontal perpendicular plates are added to a hand-drill machine， When an operator implements hole-punching， perpendicular|vertical hole-punching is correctly made to right-left back-front and a hole is made in the normal position which becomes a raw material with the reference point of hole-punching in the drill part 1 for a raw material at it， without bluring， the precision of a finishing grinding is improved further， Final polishing of the inner wall of a hole is carried out. Simultaneously with hole-punching， a hole inner wall can be finished and grinded by three types of functions of 1A of drill partial 1 and the rough finishing grinding parts at a front-end|tip， and the finishing grinding part 1B.
