Test Mandrel MT6 – 50 x 500 mm, Runout 0.005 mm (Metav IndustryLine)

The Test Mandrel MT6 – 50 x 500 mm, Runout 0.005 mm is a hardened gauge-steel mandrel for precise runout testing and spindle alignment in machine tool maintenance and quality control.

• Runout accuracy 0.005 mm
• Hardened gauge steel construction
• MT6 taper for spindle checks
• Complies with DIN 229

Ensure spindle concentricity with micrometre-level certainty

The mandrel delivers 0.005 mm runout, a tolerance that supports accurate spindle alignment and reliable concentricity checks on rotating tooling. This level of precision reduces the need for repeated adjustments and limits scrap caused by eccentric rotation. The controlled runout is particularly important when verifying high-speed spindles or precision chucks; by measuring and correcting the spindle axis early, downstream machining variances are minimised and process stability improves. The mandrel’s defined tolerance is a measurable input for quality documentation and corrective action.

Built for repeatable workshop use and simple handling

Constructed from hardened gauge steel, the mandrel combines rigidity with wear resistance for frequent inspection routines. The Ø50 x 500 mm working section and MT6 taper permit direct use with compatible spindle bores and test fixtures. The robust design and balanced mass distribution support steady measurements across the mandrel length, while the overall build conforms to DIN 229, assuring compatibility with established gauge and inspection practices. The unit’s total length of 715 mm and weight of 12 kg reflect a stable, workshop-friendly tool that remains firm during measurement without excessive operator strain.

Practical application: how it integrates with inspection workflows

Designed for runout testing and alignment tasks, the mandrel is ready for use in spindle diagnostics, chuck checks and machine acceptance tests. The tool seats in MT6 taper fittings and provides a precise reference for dial indicators or rotational measuring systems. When used as part of a corrective routine, the mandrel helps identify bearing play, taper wear or mounting errors quickly, allowing targeted maintenance rather than broad downtime. The sturdy material choice and standard compliance also facilitate traceable measurement protocols that fit into quality-management systems.
