Product Overview
New design for 2026
Diamond stones are an essential component of any tuner's kit. The coarsest stones are used to remove burrs or case hardened metal from edges, medium stones can be used between filings to "refresh" the sharpness of an edge without taking away excessive amounts of material, the finest stones are used to smooth an edge to perfect sharpness. At minimum we recommend an X-Coarse and a Med-Coarse and a Fine.
- Swix Racing Diamond Stones have a unique diamond pattern and high diamond count, the benifits are longer lasting, durable stones with amazing cutting and polishing characteristics.
- The diamond sheet is attached to an nylon plastic backing plate for a high degree of flatness and resistance to flex.
- All stones measure 4-inches (100mm) in length.
- Longer diamond plate over previous model.
