The Hammer Black widow series of balls is designed to provide length and aggressive backend reaction for a wide variety of bowling styles. Overall bowlers can expect to see excellent all-purpose ball motion with more entry angle to the pocket and improved hitting power. The Black Widow series features the High Mass Bias Gas Mask core with added flip block for enhanced drilling versatility.

Since the Black Widow series features a High Mass Bias Core, the balls provide excellent drilling versatility by placing the pin and mass bias in different configureations. When drilling a High Mass Bias ball, the placement of the Mass Bias will have a significant Impact on changing the breakpoint shape and overall ball motion.

Tuning Ball Motion:
The coverstocks used on the Hammer Black widow series will provide good length and strong backend reaction. However, it is important to keep in mind that all bowlers have different needs. the Black Widow coverstock can easily be sanded to a rougher grit for shorter hook motion in oil or polished for more length, more aggressive breakpoint and less total hook. Please consult your pro shop operator for additional assistance in tuning ball motion.

Ball Care:
It is imperative to maintain your new Hammer Black Wido by cleaning the coverstock immediately after each bowling session using bowling ball cleaning products designed for reactive balls. Hammer highly recommends POWERHOUSE ENERGIZER BALL CLEANER applied with a micro-fiber towel to remove the dirt and oil from the surface of the ball.
