Abstract

PURPOSE:To allow adjustment of recess angle to be formed at the cutting edge of a drill steplessly by a method wherein adjustment of the longitudinal reciprocating movement of the rotary shaft with a chuck to hold a drill can be made steplessly by the rotary operation of a pressing board. CONSTITUTION:A hollow rotary shaft 21 which is fixed with a chuck 20 to hold a drill at its end is inserted to the bore of the supporting body 17 and holding board 23 so that it can rotate and slide longitudinally freely. The board 23 is fixed to the supporting body 17 with bolts 22. A compression spring 24 is installed between shaft 21 and drill 25 so that rotating shaft 21 is pressed to the direction of cutting edge of the drill, and annular groove and hole 38 are cut to the disk portion 36 of the holding board 23, to which a face cam 40 is inserted. A pressing board 60 is attached to the body 61 of the holding board 23 by thread, and operation dial and scale are prepared on the outer circumference of the pressing board so that it can be operated from outside and establish recess angle of the cutting edge of a drill.
