Whether you’re a seasoned bowler or just getting started, sooner or later you’re going to need to know how to drill a spare bowling ball.

In this blog post, we’ll walk you through everything you need to know, from choosing the right size drill bit to creating the perfect finger holes.

How To Drill A Spare Bowling Ball?

Before we get started, there are a few things you’ll need:

  • A bowling ball
  • A power drill
  • A sharp drill bit 
  • A drill press (optional, but recommended)
  • A ball plug (optional)

Now let’s get started!

Choosing the Right Drill Bit

The first step is to select the right size drill bit. The most important factor here is the diameter of the bit, as this will determine the size of the holes you drill. A good rule of thumb is to choose a bit that is 1/16″ smaller than the maximum diameter allowed by the rules of your bowling league.

Creating the Finger Holes

Once you’ve selected the proper drill bit, it’s time to start drilling. If you have a drill press, we recommend using it to ensure that your holes are perfectly straight. If you don’t have a drill press, you can still hand-drill your ball, but it’s more difficult to get straight holes.

Start by drilling a hole in the top of the ball, directly above the center of the mass (the heavy spot). This is where your thumb will go. Next, drill two holes side-by-side in the bottom of the ball, symmetrical to the top hole. These will be for your middle and ring fingers. Finally, drill a hole in the back of the ball for your index finger.

You may want to start with smaller drill bits and gradually increase the size until you reach the desired hole diameter. This will help to prevent the drill bit from slipping and creating an off-center hole.

Plugging the Holes (Optional)

Once you’ve drilled all of the holes, you may want to plug them with ball plugs. This is not required, but it can help to prevent the holes from enlarging over time.

To plug the holes, simply insert the plug into the hole and tap it into place with a hammer. Start with the thumb hole and work your way around to the index hole.
