This option is best for recreational bowlers who are getting their first bowling ball or have not had a ball professionally fit for them. Having a ball drilled at your local pro shop can cost as much as $50 or more. Our standard drilling options come in five basic sizes in both right and left hand. (X-Small, Small, Medium, Large, X-Large)

Below are five examples of typical hole sizes you will find in house balls at the local bowling alley.

Need help choosing a size? No problem!
Example: You like the 8 lb ball but the holes are too small. The 12 lb ball fits good but it's too heavy. The answer would be to purchase an 8 lb ball with Medium Standard Drilling. It's that simple!

There isn’t a person on this planet that will argue against the fact that Hammer made the best urethane bowling balls back in the day. There is no doubt in our minds bowlers looking for the ball reaction that dominated the 80’s and early 90’s will find it in our new Black Urethane! 

FCC Rating (16): The overall strength of the Black Urethane is perfect for medium to light oil patterns. This throwback will really excel on shorter oil patterns. 

FINISH (10): The 500 Abralon gives ultimate traction in the oil which translates to ultimate control at the back end of the lane. 

CORE (2): Our new LED core design is a modern version of the traditional light bulb shape that was so popular back in the day. 

COVER (4): Our Urethane cover is the main ingredient in this masterpiece. Unlike modern covers that produce a violent reaction at the breakpoint, this proven staple is all about giving the user ultimate control of the entire lane.
