Precision inside measurements for tight bores and through-holes
Three-point inside micrometers, also known as inside micrometers and bore micrometers, provide highly accurate internal measurements for bores, through-holes and other confined areas, enabling reliable diameter and form checks during metalworking. These instruments are available in pistol-grip and compact rod designs, with analogue models featuring verniers and option to fit a dial gauge, while digital versions offer resolutions down to 0.001 mm, data outputs such as USB or RS-232 and advanced functions like absolute and incremental measuring. Accessories such as interchangeable anvils and extensions (100 mm and 150 mm) expand reach into deep bores, and models with microcomputer control even support wireless data transfer for streamlined process integration.

Robust design for everyday workshop use Built to withstand practical shop conditions, the gauge features IP65 ingress protection to resist dust and light jets of water, and a substantial overall build weight of 1.8 kg that gives a steady feel when measuring. The two measuring heads provide flexibility across the stepped range (12–16 and 16–20 mm), while the supplied setting ring and extension support simple calibration and extended reach where required. Delivery includes a protective transport case for safe storage and handling between measuring stations, contributing to long service life and reliable performance on the shop floor. Practical benefits and application fit For applications such as bore inspection in small housings, quality control of blind‑hole production or final checks before assembly, the instrument offers direct benefits: reduced rework through precise internal diameter verification and faster inspection cycles thanks to the digital readout and data output. The carbide faces lower wear rates compared with standard steel contacts, which reduces maintenance frequency and ensures consistent readings across batches. This makes the gauge suitable for both single‑station inspection and integration into a small inspection cell.

12–20mm Three-Point Internal Measuring Set, Two-Piece, Chrome-Plated Scale And Vernier, For Blind Holes, Wooden Case - Metav IndustryLine
Take advantage of the combination of high mechanical precision, a compact 12–20 mm measuring range, and robust carbide measuring faces for dependable internal measurements; order the instrument directly via Metav Werkzeuge or consult the Metav team for application advice. Three-point internal micrometer set M312.175 — Analogue internal micrometer, 12–20 mm, Metav IndustryLine Three-point internal micrometer set M312.175 is a compact analogue instrument designed for accurate measurement of internal diameters and blind bores in precision workshops and inspection stations High precision 0.005 mm accuracy Carbide measuring faces for long life Three-point contact for stable centring Two-piece set with extension rod Ø11.7 mm Stable centring for repeatable internal readings The three-point contact geometry ensures the measuring anvils centre reliably inside bores, reducing eccentricity during measurement. With a 12–20 mm range and an analogue vernier reading of 0.005 mm, the instrument delivers a high level of repeatability suited to fine mechanical work. The construction follows DIN 863, which standardises dimensional inspection practice and supports reproducible results in routine quality control. The matt chrome-plated scale and vernier provide low reflectivity for clear sighting and reduce the risk of misreading in mixed workshop lighting. Durable construction that preserves accuracy over time Wear resistance is increased by carbide measuring faces, which maintain measurement integrity when the anvils contact metal surfaces repeatedly. The matt chrome-plated scale and vernier are corrosion-resistant and easy to clean, helping to sustain accuracy without frequent service. Supplied as a two-piece set with an extension rod Ø11.7 mm, the equipment adapts to a range of internal geometries while remaining compact for bench and toolroom use. These features combine to lower lifetime cost through extended service intervals and fewer replacements. Practical calibration and adaptation for blind bores The instrument is designed specifically for internal diameters and is suitable for blind bores, where the three-point contact gives secure engagement without the need for through-holes. A setting ring (Ø16 mm) is provided for zeroing and verification of the mechanical scale. The analogue mechanism is simple to operate and robust under workshop conditions, offering a straightforward measurement workflow that integrates easily into inspection routines. For specialised tasks or integration into a larger metrology setup, the set’s modular nature supports quick adaptation with the included extensions.

Measure deep bores accurately with three-point inside micrometers
Three-point inside micrometers, also known as 3-point inside micrometers or three-point internal micrometers, are precision instruments designed for accurate internal diameter measurement in bores, through holes and other confined areas. They are available in analogue and digital versions and in several form factors, from pistol-grip models to compact rod-style designs for restricted spaces.
How these micrometers work and where they pay off
The instrument uses three symmetrically arranged measuring tips that expand to contact the bore surface, delivering a stable centre reference and reducing sensitivity to positional error. This makes three-point inside micrometers indispensable for inspection of multi-step bores, precision components and routine quality control in production and workshop environments. Digital variants offer incremental and absolute measuring modes, presets and direct data transfer, while analogue models retain robust simplicity where a no-frills solution is preferred.
Clear benefits that improve throughput and quality
- Reduced rework and faster setup thanks to the three-point contact geometry, which centres automatically and minimises alignment errors.
- High measurement precision with digital models offering ±2 µm accuracy and a resolution of 0.001 mm, supporting tight tolerance control.
- Flexible data handling: Bluetooth transmission to a computer, smartphone or tablet over almost 50 metres, plus USB, RS-232 and Wi‑Fi interfaces for seamless integration into inspection workflows.
- Adaptable measuring range through exchangeable jaws and extensions available in 100 mm and 150 mm lengths, enabling measurements in deep bores.
- Ergonomic options such as pistol-grip variants for comfortable repeat measuring and compact rod designs for confined spaces.
