Three‑Point Internal Micrometer M312.463 — 87–100 mm

Three‑Point Internal Micrometer M312.463 for precise internal and blind‑hole measurement in machining and toolmaking

• Three‑point internal micrometer 87–100 mm
• 0.001 mm resolution for fine measurement
• Delivered in robust transport case
• Designed for blind‑hole measurement
• Matt‑chromed scale and vernier for clear reading

Precision that reduces rework

The instrument delivers a 0.001 mm reading step and an overall accuracy of 0.005 mm, enabling fine inspection tasks where small deviations matter. The Three‑Point Internal Micrometer (M312.463) converts the spindle motion into consistent three‑point contact, which stabilises the Reading and reduces measurement scatter when gauging internal Diameters. This level of precision minimises rework and supports quality control in serial and single‑piece production.

Optimised for blind‑hole and internal features

Built specifically for the measurement of Blind‑Hole bores, the tool includes an Adjustment Ring set for quick zeroing and supplied Extension Rods (152,4 x Ø23,5) to reach recessed features without compromising stability. The triple‑contact head seats consistently in cylindrical bores, so operators obtain a reliable mean Diameter without repeated repositioning. This design is especially useful for checking stepped or counterbored components where access is limited.

Ergonomics and workshop durability

A matt‑chromed Scale and Vernier improve contrast for manual Reading while hardened Measuring Faces and a balanced weight (approx. 4.4 kg) give the Micrometer a reassuring hand‑feel that resists twist during measurement. Supplied in a protective transport case, the set is ready for use on the shop floor and for secure storage between shifts. The sturdy Construction supports frequent handling and reduces the risk of accidental damage during transport.

Who benefits most from this instrument

This Measuring Instrument targets Precision Work in toolrooms, jig and fixture production, and quality departments that require repeatable internal measurements in the Micro class (10–100 mm). Because of its three‑point contact and fine Resolution, it is well suited to machinists, metrology technicians and inspection personnel who check blind or deep bores where conventional Callipers cannot deliver the same reproducibility.

FAQ

How precise is the micrometer for workshop inspection?
The Three‑Point Internal Micrometer M312.463 (Metav IndustryLine) offers a reading resolution of 0.001 mm and a stated accuracy of 0.005 mm, making it suitable for fine internal measurements and quality checks in production.

Can the micrometer measure blind holes reliably?
Yes. The M312.463 is specifically designed for Blind‑Hole measurement, with three‑point contact geometry and supplied Extension Rods to reach recessed bores while maintaining repeatable contact.

Does the delivery include a case and extensions?
Delivery of the Metav IndustryLine micrometer includes a robust Transport Case and the specified Extension Rods (152,4 x Ø23,5), so the instrument is protected and ready for on‑site use.

What makes this instrument preferable to standard callipers?
Compared with conventional Callipers, the three‑point head and fine 0.001 mm reading of the M312.463 produce more reproducible internal Diameter values, especially in counterbores and stepped bores where single‑point contact can vary.

Which application fields is this micrometer aimed at?
The Metav IndustryLine Three‑Point Internal Micrometer is aimed at Toolrooms, Fixture Makers and Quality Control departments that need Micro‑range internal measurements (87–100 mm) with high repeatability.
