Caliper Disc 85×150 INSIZE 4780-85A — precision measuring disc for gauging and thickness control

INSIZE 4780-85A is a caliper disc with dimensions 85×150 mm designed for precision measurement tasks. This compact measuring disc provides a stable reference surface for gauging, thickness control and dimensional checks in workshop and quality control environments. The tool is intended for use where a small, rigid comparator is required to verify part thickness, flatness and repeatability of measurements.

Advantages

The caliper disc is manufactured to consistent dimensional tolerances to ensure repeatable results during comparative measurement. Its compact footprint and rigid construction make it easy to position against workpieces and inside fixtures. The design facilitates quick verification of thickness and helps reduce variation when performing routine checks. Materials and finishing are chosen to provide a stable, wear-resistant surface suitable for workshop use.

Suitable for

• Thickness control of metal, plastic and composite parts
• Comparative gauging in production and inspection stations
• Dimensional checks on small flat components
• Use as a reference or spacer in fixtures and jigs

Key specifications

• Overall dimensions: 85 × 150 mm
• Function: disc-type caliper for gauging and thickness measurement
• Form: compact, flat measuring disc for stable contact
• Primary use: comparative measurement and thickness reference

How to use

Place the caliper disc on a clean, stable surface or secure it in a fixture if required. Bring the workpiece into contact with the disc face and perform comparative measurement using a dial caliper, micrometer, or height gauge as appropriate. Ensure contact surfaces are free of debris and that measurements are taken at consistent locations to maintain repeatability. For routine checks, use the disc as a fixed reference and compare successive parts against it.

Usage recommendations

Store the disc in a dry, dust-free environment when not in use and avoid exposure to corrosive agents. Clean contact surfaces with a lint-free cloth before measurement and handle the disc by its edges to minimise contamination. Verify calibration of measuring instruments regularly to ensure overall measurement accuracy when using the disc as a reference.
