• [3-PIECE SET]: Includes three precision honing tools sized 1-1/8", 2", and 3"–4" (note: 3" and 4" share same stone dimensions but differ in shaft design), all with fine-grit grinding stones for consistent cylinder wall finishing.
• [ADJUSTABLE THREE-JAW DESIGN]: Knurled tension nut allows precise, tool-free control of stone pressure—ensures uniform for contact with cylinder bores from 3/4" to 7" (19–177 mm) for ACROSS all units.
• [FLEXIBLE SELF-CENTERING SHAFT]: Engineered spring-tempered shaft automatically centers during rotation, minimizing operator fatigue and delivering smoother, more concentric honing results on automotive and small air-cooled engine cylinders.
• [OPTIMIZED STONE DIMENSIONS]: Each stone features purpose-built length and width—28×6 mm (1-1/8"), 51×7 mm (2"), 76×10 mm (3"), and 100×11 mm (4")—for aggressive material removal and fine for SURFACE refinement in for one pass.
• [VERSATILE ENGINE APPLICATIONS]: Designed for use with grinders or drill-powered setups; ideal for rebuilding car, truck, tractor, bus, and industrial engine cylinders where bore geometry restoration is critical.
