Hammer Effect High Performance Bowling Ball The new Hammer Effect is unlike any other; it is the first ball to be poured in four colors. The gorgeous appearance isn’t the only thing that will turn heads; the Hammer Effect’s clean and aggressive mid-lane and backend performance is unparalleled in the High Performance category. The Hammer Effect introduces a new core shape called Huntsman and has physical features that will remind you of other famous Hammer balls like the Vibe and Black Widow, creating optimum performance on the lanes. Along with the new core, we’ve upped our HK22 game with this new version that takes responsiveness to the next level. Once you see what the Hammer Effect does on the lanes, you’ll want HK22 – Cohesion Pearl to be used more and more.

This removes the weak spot in the drilling area, greatly reducing the possibility for cracking and providing for a wider range of layouts. The DOT manufacturing process marks the low RG axis with a small circle engraving. Learn More about Durable Optimization Technology Hammer Effect - Tech Sheet Hammer Asymmetric Drilling instructions
