Hammer is excited to introduce a revolutionary ball – actually a game-changer for bowlers seeking alternatives to traditional urethane ball reaction. With recent changes to PBA rules regarding traditional urethane, Hammer took on the challenge of producing a ball that would mimic the performance attributes of the famous Purple Pearl Urethane Hammer without using urethane… and we nailed it. The NU Blue Hammer is “not urethane” but delivers a urethane ball motion. It is versatile, smooth, consistent, and predictable, making it ideal for challenging lane conditions. Bowlers will experience all the advantages of a reactive ball that can be used in any competition while benefiting from the classic Purple Pearl Urethane ball motion that has dominated the lanes for years.

    Hammer NU Blue Hammer

    Posted by Bob Newman on Dec 5th 2023

    The NU Hammer is a nice option for short patterns & and should work on most house shots. It is very smooth and creates a controllable arc to the pocket. I drilled a pin up and a pin down to match my Purples and you do play in a very similar part of the lane. The Purples do pick up sooner, but the NU's are stronger through the pocket. If I'm bowling a Senior PBA event where I formerly threw Purple, I'm throwing the Hammer NU.

    NU Hammer

    NU Hammer, I drilled this strong for me, 30x3x30. I was able to throw it on burned up house pattern and fresh. It looked great on the burned-up pattern, I was able to get left and it recovered and drove through the pins perfectly. On the fresh I had to square up and play up the oil line. This allowed for some mis room both directions and the ball flat struck a lot. It is cleaner than the Purple Hammer, but much slower to respond than any reactive I have thrown. Surface prep will be key to get that Urethane type motion if that is your goal. Hope this helps!

    Light=Med Oil ball, this is not Urethane, I drilled mine up 60x5x35 compared too the Purple Hammer, I find the NU to be controllable and with my slow ball speed I did not get Over/under. Great job Hammer.

    I drilled mine 30 X 4 ½ X 50. The new NU Blue Hammer is the perfect piece for bowlers looking for an alternative to the traditional urethane ball reaction. The same LED core from the Purple Pearl Urethane is paired with the new Not Urethane cover. The NU Blue Hammer is an excellent mix of the Purple Pearl Urethane and Purple Reactive. Even though the NU Blue Hammer is not urethane, it still gives you a urethane shape. It is a very smooth and predictable piece. Plus, the NU Blue Hammer is great for blending out challenging tournament conditions, and you get all the advantages of a reactive ball. The release date is 11/16/23! Pre-order yours today!
