Three-point internal measuring set (50–100 mm), 4-piece – Metav IndustryLine

A Three-point internal measuring set designed for precise measurement of internal diameters and blind bores in the 50–100 mm range, supplied as a four-piece set for stepped or overlapping measurements.

• Three-point internal measurement principle
• Measuring range 50–100 mm, 4-piece set
• Accuracy 0.005 mm per DIN 863
• Hardened measuring faces and matt chrome scale

Accuracy that reduces rework and inspection time

The four-piece set delivers 0.005 mm accuracy, providing a verifiable basis for in-process checks and final inspection. The high resolution lowers the probability of rejects and limits rework cycles, so production flow is maintained. When integrated into a measurement routine, this level of repeatability supports tighter tolerances and more reliable statistical process control.

Reliable internal measurement of blind holes and bores

Built on the three-point principle, the instrument measures internal diameters with centralised contact, making it particularly effective for blind holes where conventional calipers cannot reach. The stepped range across the four inserts enables measurement of overlapping diameters without tool changes, improving throughput when many sizes must be checked in succession.

Durable construction for workshop environments

With a matt chrome-plated scale and hardened measuring faces, the set resists wear from routine handling and contact with machined surfaces. The analogue nonius is easy to read under workshop lighting, while the robust design minimises sensitivity to accidental knocks—delivering longevity and consistent results between calibrations.

Standards and practical accessories for immediate use

Conforming to DIN 863, the set is supplied with setting rings 62 and 87 for fast calibration of the inserts and stable reference checks. The four-piece format covers 50–63, 62–75, 75–88 and 88–100 mm intervals, allowing quick adaptation to common bore sizes in metalworking and component assembly. This combination supports efficient quality routines in machine shops and tool rooms.

FAQ

How precise is the measuring set for routine inspection?
The Metav IndustryLine three-point internal measuring set offers an accuracy of 0.005 mm, making it suitable for fine workshop inspection and quality control tasks where repeatable internal diameter measurement is required.

Can blind holes be measured reliably with this set?
Yes. The instrument is specifically suitable for blind-hole measurement, using the three-point contact principle to centre reliably inside bores that do not go through the workpiece.

What sizes are covered by the four inserts?
The set covers incremental ranges: 50–63 mm, 62–75 mm, 75–88 mm and 88–100 mm, allowing measurement across common diameter bands without the need for intermediate tools.

Are setting or calibration accessories included?
Setting rings 62 and 87 are provided for fast verification and calibration of the inserts, enabling immediate use in workshop measurement procedures.

To which standard does the set conform?
The set is manufactured in accordance with DIN 863, ensuring compatibility with standard workshop measurement expectations and traceable inspection routines.
