Victor Thruster Hammer

The Victor Thruster Hammer (TK-HMR U) brings the head-heavy Thruster feel to an approachable, easy-to-swing package. It pairs a head-heavy balance with a flexible 7.0mm shaft, so newer and developing players can generate depth on clears and real pace on smashes without needing a fast, fully developed swing.

A Power Box head lets the frame accept tensions up to 32 lbs in the 4U version, giving the racket room to grow with a player as their technique improves.

Power Box Frame — A box-section frame that boosts stability and resistance to twisting, allowing the racket to handle higher string tensions.

Single-Pass Grommet System — Grommet holes that each carry a single pass of string, reducing friction between strings to limit tension loss and extend string life.

Catapult Structure — A frame reinforcement that stores energy during the swing and releases it at impact for extra smash power.

Fiber Reinforced System (FRS) — A multi-layer carbon fibre construction that adds elasticity and keeps the frame stable and controllable at higher string tensions.

The Thruster Hammer suits beginner-to-intermediate players who already know they like to attack. The flexible shaft does much of the work on longer shots, while the head-heavy balance adds weight behind smashes and clears, making it a good first step into power rackets before moving on to stiffer Thruster models.

Best for: Developing power players, recreational singles players, and anyone wanting an affordable head-heavy racket.
