Dynaspheres – Cue-Ball Tungsten 57.2mmwith 2 black triangles,

What it is. The Dynaspheres Pool Tungsten 572 is a precision-engineered phenolic resin cue ball built to the 57.2mm American and international pool standard. It delivers competition-level consistency — tight dimensional tolerances, certified roundness, hardness rated at or above 59 Rockwell E — in a replacement format suited to commercial venue use. E-Service is the official UK distributor for Dynaspheres, supplying operators directly with genuine product to full manufacturer specification.

Minimal marking by design. The Tungsten sits at the restrained end of the Dynaspheres 572 range. The Palladium uses six black rotors; the Rhodium uses six black triangles; the Tungsten uses two. That difference is deliberate. Two triangles give the player a directional spin reference — enough to read ball behaviour on break shots and draw — without the visual density of the six-marker variants. It suits pub environments, social pool halls, and leisure venues where operators want a step up from a generic replacement while keeping a near-standard aesthetic at the table.

The commercial case. The Tungsten 572 holds ±0.08mm on diameter, ±1.0g on weight, and ≤0.03mm on roundness — tolerances that translate directly into consistent play and reduced wear on pockets and cushions. Phenolic resin construction resists chipping, staining, and the surface degradation that shortens the life of cheaper polyester alternatives. At 169g, it meets the weight standard expected on American and international tables without adjustment.
