INSIZE measuring mandrel WALECZEK.POM.FI5.01/0.001 model 4110-5D01

INSIZE WALECZEK.POM.FI5.01/0.001 model 4110-5D01 is a precision measuring mandrel designed to provide a stable, defined reference diameter for internal measurement and calibration tasks. Manufactured by INSIZE for use in workshops and quality control environments, this mandrel assists in verifying bore gauges, setting up inspection fixtures, and checking the accuracy of internal measurement instruments.

Advantages

The measuring mandrel offers a consistently defined, calibrated diameter that reduces variability in internal measurement checks. Its construction is intended for stable contact and repeatable results when used with bore gauges or other internal measuring devices. The tool simplifies calibration workflows and helps maintain traceability of measurement routines in production and inspection settings.

Suitable for

• Calibration of bore gauges and internal micrometers
• Verification of internal measurement instruments in quality control
• Setting up inspection fixtures and measurement rigs
• Workshop checks and routine dimensional verification

When it may not be suitable

This mandrel is intended specifically as a reference for internal diameter checking and is not designed for external measurement or as a replacement for complete gauge blocks or master rings when those are required for traceable calibrations. It may not be appropriate where temperature-stabilized reference standards or higher-level accredited calibration artefacts are required for calibration certificates.

Key specifications

• Function: internal diameter reference/mandrel for measurement and calibration
• Application: use with bore gauges, internal micrometers and inspection setups
• Precision: manufactured for fine dimensional control suited to precise checking tasks
• Construction: designed for stable seating and repeatable contact with internal measuring probes
• Environment: suitable for workshop and production quality-control use

How to use

Mount the mandrel securely in a stable fixture or hold it with appropriate support to avoid deflection. Allow the mandrel and measuring instruments to reach ambient temperature before performing checks to reduce thermal error. Gently insert the bore gauge or internal measuring device and take readings from multiple positions if needed to verify concentricity and repeatability. Record results and compare them with expected values for pass/fail decisions or further adjustment of measuring instruments.

What to consider before purchase

• Confirm that the mandrel's nominal diameter and precision level match your measurement requirements
• Ensure compatibility with the bore gauges or internal measuring tools you intend to use
• Consider the need for temperature control or accredited reference standards for traceable calibration

Usage recommendations

Use the mandrel in a temperature-stable environment, handle it with care to avoid nicks or deformation, and document measurement procedures to maintain consistent and repeatable internal diameter checks in workshop and quality-control processes.
