  • Drill machine head is equipped with electric motor, for transmission of rotary motion into spindle at some speed via the V-pullers or V belts.
  • Material of construction of spindle is alloy steel. It is provided for rotation & mover vertically up- down through the sleeve.
  • A pinion with rack arrangement is Constructed to the spindle for movement of position vertically up-down.
  • Drill chuck is provided at the end of spindle, to turn & hold the drill bits.
  • Adjustable workpieces table is provided for stable & safe operation of drilling machine.
  • Base plate having a heavy casing that support structure.
