Precision Steel Lathe Alignment Test Bar Mandrel – Double-Ended MT1–MT0 | EN31 Tool Steel, Hardened & Precision Ground | for Headstock–Tailstock Alignment & Eliminating Taper Turning

The Assorts Precision Steel Lathe Alignment Test Bar Mandrel (Double-Ended MT1–MT0) is engineered to deliver high accuracy for small lathes and precision machines. This dual-taper design offers maximum versatility—use either the MT1 or MT0 end depending on your spindle or tailstock taper requirement. Made from premium EN31 tool steel, this alignment mandrel provides exceptional hardness, rigidity, and long-term stability. Each piece is hardened to 52 ±2 HRC and precision ground to tight tolerances, ensuring highly accurate reference surfaces for alignment and calibration tasks. Used to eliminate taper turning on long workpieces, this tool helps machinists verify and correct headstock–tailstock alignment, spindle axis errors, and geometric inaccuracies. A must-have tool for workshops, tool rooms, production units, and machine maintenance professionals.
