So, join us on this enlightening journey as we delve into the mechanics of finger holes in bowling balls.
What are Finger Holes in Bowling Balls?
Finger holes in bowling balls are small, drilled-out indentations on the ball’s surface that allow bowlers to grip and control it when throwing it down the lane. These holes are typically placed in a triangular configuration with two holes for the fingers and one for the thumb. The size and positioning of the finger holes can significantly affect a bowler’s performance, making it essential to choose the right size and style for your individual needs.
Purpose of Finger Holes
The primary purpose of finger holes in bowling balls is to provide bowlers with a secure and comfortable grip on the ball. Bowlers can exert precise control over the ball during the delivery and release by inserting their fingers into the holes. This control is crucial for achieving accuracy and consistency in the ball’s trajectory and can significantly impact a bowler’s overall performance.
The finger holes also allow bowlers to achieve a more efficient and effective ball release. By correctly inserting their fingers into the holes and applying the correct grip technique, bowlers can generate increased revolutions on the ball, resulting in enhanced hook potential and pin carry. This improved release can significantly contribute to a bowler’s ability to knock down more pins and achieve higher scores.

Types of Finger Holes
Bowlers can choose from various types of finger holes, each offering different advantages and benefits. The most common types of finger holes are the conventional fingertip, thumb-in, and thumb-out grip.
The conventional grip is the most basic and traditional style, where the fingers and thumb are inserted fully into the holes. This grip offers a secure and stable hold on the ball but may limit the bowler’s ability to generate a high rev rate.
The fingertip grip, on the other hand, allows for a more dynamic release. With this grip, only the tips of the fingers are inserted into the holes, creating a lighter grip pressure and increasing the potential for a higher rev rate.
The thumb-in grip involves inserting the thumb fully into its hole while keeping the fingers barely inserted or hovering over their respective holes. This grip provides bowlers with a more controlled and precise release and the ability to generate maximum revs.
Lastly, the thumb-out grip, known as the “two-handed” style, is a newer technique popularized by certain professional bowlers. Both hands support the ball in this grip, with the thumb not inserted into a hole. This grip allows maximum rev potential and power but requires considerable strength and control.
Choosing the Right Finger Hole Size
Selecting the appropriate finger hole size is crucial for maximizing comfort, grip, and overall performance. Using finger holes that are too small or too large can lead to discomfort, lack of control, and even injury. Therefore, it’s essential to determine the correct finger hole size before drilling the ball.

Importance of Finger Hole Size
The size of the finger holes affects how the bowler’s fingers fit into the ball. If the holes are too tight, it can cause discomfort, restricted movement, and a lack of proper release. On the other hand, if the holes are too loose, the bowler may not have enough control over the ball and may experience slipping while throwing.
Determining the Correct Finger Hole Size
To determine the correct finger hole size, it’s recommended to consult with a professional ball driller or visit a pro shop. These experts have the knowledge and experience to measure your hand and recommend the right size based on various factors, such as hand span, finger circumference, and finger flexibility.
The ball driller will measure your hand using specialized tools like a fitting ball or a digital caliper. They will also consider your throwing style and personal preferences to ensure a proper fit. Communicating any discomfort or issues you’ve experienced with previous finger hole sizes is essential to help the ball driller make the best recommendations.
Drilling Finger Holes in Bowling Balls
Once you have determined the correct finger hole size, it’s time to drill the holes into the bowling ball. A professional ball driller typically does this with the necessary expertise and equipment.
The Drilling Process
The drilling process involves carefully marking and positioning the holes on the ball’s surface according to the chosen layout. The ball driller will use specialized drilling equipment, such as a drill press or a milling machine, to create the holes. The drill bits will depend on the grip style and hole configuration.
Positioning of Finger Holes
Positioning finger holes is essential for achieving the desired grip and release. When determining the hole placement, the ball driller will consider factors such as the bowler’s hand size, flexibility, and personal preferences. They will also consider the chosen grip style and the desired ball reaction to achieve optimal results.
Custom Fingertip Drilling
For bowlers using the fingertip grip, custom fingertip drilling is often recommended. This involves drilling the holes so that the fingertips rest slightly beyond the holes, allowing for a lighter grip and increased rev potential. Custom fingertip drilling can be adjusted and tailored to the bowler’s specific needs and style, providing a more personalized fit and improved performance.

Finger Hole Placement and Layout
The placement and layout of the finger holes play a significant role in the overall performance of a bowling ball. Different hole positions and layouts can affect the ball’s motion and hook potential, allowing bowlers to fine-tune their game to suit their style and lane conditions.
Finger Hole Positions
The finger holes can be positioned in various locations to achieve different results. Placing the holes closer to the center of the ball creates a more stable and controlled roll, suitable for straighter shots or oily lane conditions. Moving the holes toward the positive axis point (PAP) increases the ball’s potential for hooking, which is ideal for drier or more reactive lane surfaces.
Finger Hole Layouts
The layout of the finger holes refers to the specific arrangement of the holes on the ball. The most common is the conventional grip layout, where the finger holes are evenly spaced in a triangular configuration. This layout provides a well-balanced feel and stability, suitable for beginners or bowlers who prefer a consistent release.
The layout can vary depending on personal preferences and desired ball reaction for bowlers using the fingertip grip. Some may prefer a forward pitch layout, where the finger holes are angled towards the front of the ball, promoting an earlier hook. Others may opt for a reverse pitch layout, with the holes angled towards the back, allowing for a later hook.
Grip and Release Techniques
Different grip and release techniques can enhance a bowler’s control and performance. Here are some of the most common grip styles used in bowling:
The conventional grip is the traditional style, where the bowler inserts all fingers and thumbs into the respective holes. This grip provides a secure and stable hold on the ball, offering reasonable control and accuracy. It is commonly used by beginners or bowlers who prefer a more straightforward approach.
The fingertip grip involves inserting only the fingertips into the finger holes, with the thumb inserted fully into its hole. This grip allows for a lighter grip pressure, increasing the potential for higher rev rates. It empowers bowlers to generate increased hook potential on the ball, leading to improved pin carry and scoring potential.
The thumb-in grip is a variation of the conventional grip, where the bowler inserts the thumb fully into its hole while keeping the fingers barely inserted or hovering over their respective holes. This grip gives bowlers a very controlled and precise release, offering optimal rev potential and the ability to generate maximum power.
The thumb-out grip, also known as the “two-handed” style, is a newer technique that has recently gained popularity. In this grip, the bowler uses both hands to support the ball, with the thumb not inserted into a hole. This grip allows maximum rev potential and power but requires considerable strength, coordination, and control.
