Basic Drilling Service
bowlingball.com offers a basic drilling service for the recreational bowler who would like to own their own bowling ball. This is a basic conventional layout using an average for the span and hole sizes.
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.
Any ball purchased with this Basic Bowling Ball Drilling option may not be returned for any non-manufacturer warranty issues.
Please allow up to 14 days for the service before your order will be shipped
