Methods of producing guide holes min. 2.5 x DC 1. ilot hole as guide bush The guide hole should be drilled to tolerance mm ( inch) (H7) larger than the gun drill diameter. As flat bottom as possible is preferable. A reduced feed rate can be used when entering the material. 2. Feeding the gun drill into the guide hole Caution: Outside the hole, the gun drill should not be rotating. Feed to insert the drill into the guide hole while supplying cutting fluid. 3. Start drilling Start cutting rotation and cutting feed. 4. After the hole been drilled Rapid return. Stop at the guide hole position. Stop the cutting rotation and coolant supply. ull the gun drill out from the workpiece. 18
