Ball Drilling Instructions

Please be aware these instructions are intended for the use of a professional ball driller. Visit your local pro shop for your ball drilling needs. Do not attempt to drill an OnTheBallBowling product yourself as we will not cover any issues you may then have under warranty.

First locate the serial numbers on the ball. The Heavy Spot (CG) is located just above the serial numbers indicated by a punch mark. This is where you should locate the center of grip.
