Spinfire Inferno Stringing Machine

The Spinfire Inferno is a professional tabletop stringing machine designed for players, coaches, clubs and pro shops who want consistent, accurate string jobs without the cost of an electronic machine. Its smooth manual crank (lock-out) tensioning system provides reliable, repeatable results and can be adjusted in either kilograms or pounds.

Built on a heavy-duty chassis, the Inferno features a rigid 6-point mounting system that securely supports the racquet frame during stringing, helping to minimise distortion while maintaining excellent access to the string bed. The large integrated tool tray keeps your essential tools within easy reach, while the turntable brake makes working on shared holes and finishing knots easier.

The latest model comes standard with the new Spinfire V50 universal clamps. These hybrid swivel clamps are designed to string tennis, squash and badminton racquets, eliminating the need to purchase separate clamp sets for different racquet types.

For faster and more convenient stringing, you can upgrade from the standard base clamps to the optional automatic base clamps when purchasing your machine. They reduce the effort required to release each clamp and help speed up the overall stringing process.

Learn How to String a Tennis Racquet

If you are new to stringing, the videos below will guide you through the complete process, from mounting the racquet through to tying the finishing knot.

For the finishing knot, we recommend using the Pro Knot. When tied correctly, it forms a compact, professional-looking knot with the string tail tucked neatly against the frame. It is quick to tie, extremely secure and works well with all modern string types.
