BowlerX.com Bowling Ball Drilling Services

Standard Drilling Service

You can determine your span by measuring the distance from the base of your thumb to the middle of the first bend of the knuckle on your middle finger. Choose the closest distance from the chart below. If your measurement falls in between two spans, go with the shorter of the two spans offered.

Our standard drilling service is recommended for the recreational bowler who would like to own their own bowling ball. This is a standard conventional layout using an average for the span and hole sizes. Standard drilling services at your local pro shop can cost anywhere from $30 to $50. Below is a table of the right handed (Reverse Ring/Middle for left handers) measurements used to drill your bowling ball.

The fit of this service is not guaranteed and minor adjustments may have to be made to the hole sizes once the ball has been received. We will finish off all the holes and the ball will be ready to bowl with once it is received. Drilled bowling balls may not be returned for any reason other than a manufacturer defect. Ball fit and reaction are not guaranteed by BowlerX.com. Drilling charges cannot be reimbursed. Please allow up to 7-14 days for the service before your order will be shipped.
