Professional Drilling Service

A comfortable grip is essential for a good release. Installing finger inserts to your ball can provide you with a consistent grip that will allow the same feel everytime you throw the ball.

Our Bowlerstore.com Pro Shops offer several different ways to drill your thumb hole. For an optimal fit, we recommend that you send us your bowling ball that feels the best to you. We can then create a custom mold of your thumb hole that we can use to create a thumb slug that will feel identical to the thumb hole on your favorite ball. If you have not had to work out your thumb much, then just the standard thumb insert will work great as well. We also utilize High End Mill/Drill machines to match up and drill oval holes if desired.

How your ball is drilled will determine the amount of reaction your ball will receive depending on your style of bowling. Some bowlers prefer the ball to go longer down the lane before hooking. Some prefer a smoother type of roll and and earlier roll. How would you like us to drill your bowling ball?

In order to drill your bowling ball, we need your hand specification/measurements. We offer several ways for you to submit your measurements to our pro shops.

Would you like your name or something engraved on your bowling ball? If so, we can do it. We can engrave one line up to 8 spaces maximum. We also offer Block or Engraved lettering.
