About Bowling Ball Drilling Patterns

Bowling is a recreational past time for some bowlers, a league activity for others, and even a career for some bowlers. How a bowling ball is drilled is an important factor in how the bowler bowls. If she can determine how her ball will travel down the lane, she can adjust for different lane conditions such as heavy oil and play accordingly.

  1. Significance

    • Controlling a bowling ball consistently is very important to both league bowlers and professional bowlers alike. Use the same throwing motion and footwork each time to control the ball. Just as important is the pattern the finger holes are drilled into the bowling ball. The drill pattern can alter how the weight shifts; thereby affecting how it rolls.

    Features

    • The drilling pattern in bowling balls vary significantly. According to the Top End Sports website, a bowling ball can have up to 12 holes drilled into it. Drilling one hole per finger in the ball is legal, as is adding a vent hole above each of the finger holes to prevent sticking. Drilling one other hole to alter the weight balance of the ball and one to show the composition of the ball are also allowed.

    Types

    • Drilling patterns of a bowling ball come in a variety of styles. Drilling a hole where either three quarters of each finger fit in, or one where just the first digit of each finger fit in are common drilling patterns. Most "alley balls" which are free to use when you go to a bowling alley have two finger holes and one thumb hole.

    Considerations

    • Arrange an appointment with a pro shop to drill your bowling ball professionally. Tell the shop about any special features you require, for example, a large hook to the pattern of your ball's path. The combination of your normal approach to the lane and release technique provide valuable information. If you do not have time to demonstrate your bowling style, describe it in as much detail as possible to get your ball drilled to perform appropriately.

    Warning

    • The drilling pattern of finger holes has a significant impact on how the ball travels down the lane. Combining the lift you place on the ball and the weight balance of the ball has a significant effect on the path of the ball on the lane. If you want your bowling ball to do anything more than go straight or have a very minor hook, it is best to turn down offers for free drilling. Instead take the ball to a pro shop or local bowling alley and have customize drilling done.
