This ball creates a big hook and never quitting ball motion!

Hammer is proud to offer the broadest range of core and cover options in bowling. We are excited to enhance the product line by adding a “big” shiny symmetric ball, the Hazmat. The Hazmat is a lower RG and higher Differential core that will help the ball pick up in the mid-lane and have a strong and continuous down-lane motion. The base cover is the extremely popular and highest-performing HK22, and we’ve used the Symtex Hybrid additives. The core and cover combination of the Hazmat creates a big hooking and never quitting ball motion that bowlers love to see.

    Best bowling ball ever

    The hammer hazmat is the best bowling ball for a kid who is averaging 168 and bowled a 182 - 230 - 204 for a 616 series


    This ball is absolutely amazing it has so much hook worth the money for sure, it is my favorite bowling ball in my bag currently.

    The Semtex hybrid coverstock helps push the ball through the front portion of the lane. The lower RG, 2.479, helps the ball read the midlane, and delivers downlane where it reads the end of the pattern and makes a strong left turn, but does not stop hooking. The ball is very continuous through the pin deck. It is a ball that is sneaky clean through the front of the lane, and the .055 differential give it more than ample change of direction to attack from steep angles. Good option to play a league condition all set, and great option for later in the day of tournaments or challenge patterns.

    One of the better looking balls I’ve drilled in quite some time and has great shelf appeal. Overall, the ball is very clean through the front parts of the lane and retains energy very well. That being said, it is a bit more angular downlane you will likely need a sound bit of friction to see the ball turn as well as you’d like. It’s certainly better for later in blocks, but has sound versatility for shorter to medium length patterns.

    Great ball

    First ball out of the bag, gives me a great baseline on how lanes are playing. Clean through the front and plenty of back end
