TECHNICAL NOTES
Drilling Poles
The following are steps for field drilling ductile iron poles. Below are the recommended drill bits that have
performed significantly better than all other drill bits tested.
Drilling:
Step 1: Apply steady pressure with pilot bit to drill through the wall of the pole.
Step 2: Immediately after the pilot bit goes through the wall, remove pressure. Do not make impact
with hole saw bit on the face of the pole.
NOTE: Making impact on with hole saw immediately after pilot bit will cause the pilot bit to bind
and break.
Step 3: Square hole saw bit to the face of the pole and apply 5-10 pounds of pressure on the hole saw
bit and drill until the bit cuts through the wall of the pole.
NOTE: Pressing too hard on the hole saw bit will significantly reduce the life of the hole saw bit
and will not speed up the drilling process.
NOTE: With proper technique, the pilot and hole saw combination should last more than 75
holes.
