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.

Benefit from reproducible internal measurements, a three‑point contact system and carbide measuring faces that resist wear; the instrument is supplied in a protective case for safe transport. Order the instrument directly via Metav Werkzeuge or ask the consultants if needed. M312.152 three‑point internal micrometer — 250–275 mm, carbide measuring faces (Metav IndustryLine) The M312.152 three‑point internal micrometer is a precision tool for reliable bore measurement in workshop and production environments, designed for internal diameters from 250 to 275 mm and equipped for repeatable contact and long service life. Three-point contact for stable internal measurement Carbide measuring faces for wear resistance Ratchet for repeatable contact pressure Delivered in protective case; no setting ring included Accurate three‑point geometry for repeatable results The three‑point contact geometry ensures centring and stability in cylindrical bores, reducing eccentricity compared with two‑point probes. Combined with the fine analogue division (reading 0.005 mm) and the specified measurement precision (±0.009 mm), the instrument provides clear, reproducible results for quality control and serial inspection. The ratchet stop maintains a constant measuring force, which in practice minimises operator‑dependent scatter and simplifies comparison of consecutive measurements. Built to withstand workshop use and long measurement cycles Robustness is achieved through carbide measuring faces, which offer high resistance to abrasion in frequent use, and a matt‑chromed scale and vernier that reduce glare and preserve legibility. The ratchet mechanism contributes to consistent contact pressure and gentle handling of delicate bores. For safe transport and protection between shifts the micrometer is supplied in a protective case; note that the delivery does not include a setting ring, so a gauge ring should be sourced separately if traceable calibration rings are required. Optimised for standard workshop ranges and practical reach Classified for the standard measuring range (100–300 mm), the 250–275 mm span strikes a balance between reach and stiffness that suits general machine‑ and metal‑work tasks such as bearing seats, housings and large bushings. The measuring depth 140 mm allows access into moderately deep bores without compromising handling. This combination of range and rigidity supports efficient inspection routines where mid‑sized components are inspected regularly. Simple handling, clear readings and maintenance guidance As an analogue instrument with a fine vernier, the device offers straightforward readings and low susceptibility to electrical interference. The vernier and scale are designed for workshop readability, and routine maintenance is limited to keeping the carbide faces clean and avoiding shock loads.

With a measuring range of 30–40 mm and an indicated accuracy of 0.005 mm, the instrument supports fine tolerance checks typical in component inspection and quality control. The integrated drum scale provides a quick visual check while the electronic readout offers exact numerical values, combining classic mechanical reliability with modern digital precision. Built to withstand workshop conditions and everyday use Engineered for routine use, the gauge features carbide measuring faces that resist wear and hold form over prolonged cycles, while a matt‑chrome scale and vernier improve legibility under workshop lighting. The unit is rated IP65, permitting use in environments where coolant mist or dust are present without compromising the measuring mechanism. Delivered complete with a setting ring and extension, and supplied in a transport case for secure storage, the tool balances robustness with practical handling for production and toolroom teams. Traceable results and efficient data handling for quality processes A clear digital display with ON/OFF/SET and ABS/INC/UNIT controls simplifies switching between measurement modes and reference points, reducing operator errors. The integrated data output RB 4.1 enables direct transfer of readings to data capture systems or SPC software, speeding documentation and improving traceability within quality workflows. Conformity to DIN 863 underlines the instrument’s suitability for routine inspection tasks where standardised measuring practice is required.

Technical data Article number: M312.237.M GTIN: 4054469162386 Manufacturer: Metav IndustryLine Standard: DIN 863 Category: Messschrauben Facts Measuring range: 30–40 mm Resolution / reading: 0.005 mm Accuracy: 0.005 mm Length: 97 mm Weight: 2.5 kg Special features Digital display with ON/OFF/SET and ABS/INC/UNIT buttons Data output: RB 4.1 IP65 protection Carbide (HM) measuring faces Drum with scale (messtrommel mit skalierung) Scale and vernier matt chrome plated Supplied with setting ring and extension Delivered in protective case Suitable for blind‑hole (sackloch) measurements FAQ How does the three‑point system improve measurement in blind bores? The three‑point contact of the M312.237.M centres automatically in the bore, reducing eccentricity and delivering repeatable diameters even in blind‑hole conditions where conventional two‑point devices can tilt. Can the digital readings be exported to a quality system? Yes. The micrometer provides a data output (RB 4.1) for direct transfer of readings to SPC or measurement software, facilitating documentation and process control. Are the measuring faces durable for production use? The measuring faces are made from carbide, providing high wear resistance and long service life under regular shop‑floor inspection cycles. Is the instrument protected against coolant and dust? The device is rated IP65, which allows operation in environments with dust and splashing liquids typical of machining workplaces, preserving measurement integrity. What accessories are included for setup and deep bores? The micrometer is supplied with a setting ring and an extension, enabling immediate calibration and extended reach for recessed or deep bores.

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.
