Assorts ISO 30 Taper Alignment Mandrel Test Bar – Precision Tool Steel, Hardened & Ground | VMC Vertical Milling Center Spindle Alignment, Air-Gauge Verified < 2 Microns, OAL 200 mm

The Assorts ISO 30 Taper Alignment Mandrel Test Bar is designed for professional machinists and service engineers who demand perfect spindle alignment in Vertical Milling Centers (VMC). Manufactured from high-quality tool steel, this mandrel is hardened and precision-ground to ensure maximum rigidity and long-term durability. Each test bar is air-gauge checked to under 2 microns accuracy, guaranteeing exceptional concentricity and straightness for precise machine setup and calibration. The ISO 30 taper ensures compatibility with most VMC and CNC spindles, while the 200 mm overall length provides the necessary reach for accurate alignment measurements. Ideal for spindle runout checks, taper verification, and machine calibration, this alignment mandrel is an essential tool for machine shops, tool rooms, and precision engineering environments.
