Additional product information:

Hammer is excited to introduce a revolutionary ball – actually a gamechanger 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.

    Great ball for the Shorter Oil Pattern or Less Oil

    Posted by Jim M. on Mar 9th 2024

    This is a very versatile ball.... Will get down lane and recover well when it hits the friction. This is also a great ball for playing an outside shot on a drier house pattern, especially if you have a lower rev rate.

    NU Blue Hammer

    Posted by Todd Allred on Mar 4th 2024

    The NU Blue Hammer impressed me with how close it really was to my Purple. It’s cleaner through the front and a few boards more down lane but still allows me to play the lanes very similar to the way I do with urethane. When my purple starts to hook early and plaque I switch over the the Blue and don’t miss a beat.

    NU Hammer

    The new blue hammer is close to urethane but not like the purple hammer which makes it a great alternative and reacts well and very controllable to house patterns.

    Hammer NU The Hammer NU is jus as expected very controllable reaction similar to the shape of the Purple Urethane but with a bit more punch downlane. Good piece for sport conditions.

    Very clean

    Posted by Bill Richardson on Jan 21st 2024

    Well it's not urethane that's for sure. Does it react like urethane? Yes it does. I drill this ball identical to a purple hammer and it hook about 3 more boards at box finish. It is a little more down lane motion but with some surface adjustments I can play right on top of a purple and a double cross. I haven't seen any deflection on lighter pocket hits playing straighter lines either with this one. Definitely a good ball to have around if the lanes get a little crazy

    Nu Blue

    Posted by Craig Hohn on Jan 21st 2024

    Hammer Nu Blue- (NOT Urethane): This ball out of box hooked like urethane, early and often. It was too much for the burned heads we bowl on. It would get downlane and not finish strong. After adjusting surface, it reacted much better. I took the OOB surface to 3000 grit, and let it lane shine, and it pushes much better. For the out-of-town tournaments i used it in the OOB finish was much better. This ball should ROLL off the end of the pattern, and should not have a big change in direction. Play with the surface on this piece, and you will have a controlled roll of the pattern for many different conditions. This is a must-have for tournament bowlers and for league bowlers to not get in trouble with balls that jump off the back of the oil pattern.

    Ball: NU Blue Hammer Coverstock: Not Urethane Core: LED Factory Finish: 500, 1000 Siaair Micro Pad Layout: 45 x 4 x 35 The NU is a very unique ball. I drilled the NU with the same 4 inch pin up layout as my Purple Hammer. The NU is a bit cleaner than the Purple Hammer which allows it to be more continuous on the back part of the lane. The attribute I like best about the NU is versatility. If I keep my hand up the back of the NU and play straighter on shorter sport patterns, it reacts very similarity to the Purple Hammer (maybe 3 and 2 stronger). The interesting part about the NU is that if I want to get left with a stronger release and circle the lane, it reacts very well. Although I have not used it much in league, I have also witnessed bowlers successfully throwing it on house patterns. Anyone from low ball speed players to high rev rate players will find a place in their bag for the NU. Chris Freeland Average Rev Rate 400 Average Speed 18 mph PAP: 4 1/8 over 3/4 up

    Posted by Mike Romero on Dec 31st 2023

    The Hammer NU Blue Hammer is great addition from Hammer. To me, this ball fits right in between the Purple Reactive and Purple Urethane. Very Smooth and predictable. I drilled mine with a 3” pin and is great on sport shots and even better on house shots. Go get this ball today!!!!

    Bad Ass Blue

    Posted by C miller on Dec 30th 2023

    Hammer's NU Blue has been out for a better part of a month and what I see out of it, compared to the purple is a ball that is cleaner up front, with more continuation down lane.
