Hammer Black Widow Tour V1 Bowling Ball

A Lower-Differential, Tour-Tuned Black Widow

About the Black Widow Tour V1

The Hammer Black Widow Tour V1 is the controllable, tour-tuned member of the Black Widow line. It pairs the asymmetric Gas Mask Low Diff Core with the HK22 Aggression Hybrid coverstock, delivering the Black Widow’s defined shape with a lower differential for a smoother, more controllable read on medium to heavy oil. It is built for the precision the best players demand.

The Black Widow Tour V1 takes the feared Gas Mask design and tunes it for control. The lower-differential version of the core produces less flare and a more even, predictable motion than the standard Black Widow, while the HK22 Aggression Hybrid cover at a sanded finish reads the midlane cleanly. The result is a controllable, tour-style Black Widow for bowlers who want shape without an overly strong backend.

Understanding the Hammer Gas Mask Low Diff Core and Hammer HK22 Aggression Hybrid Reactive

Hammer built the Black Widow Tour V1 for a controllable, tour-tuned read on medium to heavy oil. Specifically, the asymmetric Gas Mask Low Diff Core posts a 2.500 RG, a .034 differential, and a .016 intermediate differential, numbers that produce moderate flare and a smooth, defined breakpoint, while the HK22 Aggression Hybrid cover at a 3000-grit finish reads the midlane cleanly. As a result, it gives you the Black Widow’s shape with a more controllable, even motion. The per-weight specifications are listed below.

A Lower-Differential Version of the Legendary Gas Mask Core

At the heart of the Black Widow Tour V1 is the asymmetric Gas Mask Low Diff Core, a lower-differential version of the legendary Gas Mask block. At 15 lb it measures a 2.500 RG, a .034 differential, and a .016 intermediate differential, a combination that produces moderate flare and a smooth, defined breakpoint. The lower differential is what separates it from the standard Gas Mask: less flare and a more controllable, even motion.

Because the core is asymmetric, layout has a strong influence on the reaction, so your pro shop can tune the pin and intermediate differential to your game. That tour-tuned control is exactly what advanced players look for in a benchmark asymmetric.

A Sanded HK22 Hybrid for a Clean, Controllable Read

The Black Widow Tour V1 wraps that core in Hammer’s HK22 Aggression Hybrid Reactive coverstock at a 3000-grit finish. As a hybrid at a cleaner 3000-grit surface, the cover reads the midlane smoothly and controllably, so the ball gets down the lane evenly and makes a predictable, defined move rather than a sharp or early reaction.

That clean, controllable read paired with the low-differential core is what gives the Tour V1 its tour-style precision: shape and traction without an overly strong backend. Leave it at the 3000-grit box finish for a controllable read, take the surface lower for more traction, or polish it up for more length when the lanes dry.
