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.

Digital three‑point internal rapid gauge M312.344 — Digital, 6–12 mm range, Bluetooth The Digital three‑point internal rapid gauge M312.344 is a compact, high‑precision measuring set designed for rapid internal diameter checks in blind‑hole bores and other small bores in production and workshop environments Digital display with 0.001 mm resolution RB6 and Bluetooth data output for traceability Three-piece set covering 6–12 mm range 330° rotatable display for ergonomic reading Precision that shortens inspection cycles The set delivers measurement certainty by combining a resolution of 0.001 mm with an instrument accuracy of 0.004 mm, values that place these gauges in the high‑precision segment for internal measurements. The three‑point measuring principle ensures stable contact with the bore even in short blind holes, reducing alignment errors and producing reproducible readings. Classified as a micro measuring solution due to the 6–12 mm range, the instruments are optimised for fine mechanical work where compactness and stiffness of the measuring tips matter; this design minimises deflection and supports faster, repeatable checks compared with longer, less rigid probes. Seamless data capture for quality workflows Data handling is tailored for production environments: each instrument provides RB6 and Bluetooth outputs for wired or wireless capture, enabling direct logging into inspection software or handheld recorders. The display includes practical functions — ON/OFF/SET, CAL, INC, PRESET, HOLD, mm/inch and TOL — which support both quick pass/fail checks and preset measurement routines. With battery power from a 3 V CR 2032 cell and compact electronics, these gauges allow frequent on‑bench use without the complexity of fixed metrology rigs, accelerating inspection throughput while maintaining an audit trail for quality records. Ergonomic form for workshop endurance Designed in a pistol‑style quick‑measuring format, the instruments balance fast operation with robust handling: the 330° rotatable display makes read‑outs accessible in cramped setups, and the overall weight supports single‑handed operation while remaining stable during contact. The set is supplied in a transport case suited for workshop transfer and short‑term storage, protecting the delicate tips during handling. Note that the package comprises the three digital gauges only; a setting ring and extensions are not included, which keeps the kit compact and focused on routine bore verification. Practical applications and operational benefit These three‑point internal gauges are particularly effective for blind‑hole bore measurement, offering quicker set‑up than traditional three‑jaw or mandrel methods and reducing the time per inspection. The set format covering 6–12 mm in three overlapping subranges (6–8, 8–10, 10–12) streamlines variant checks on small components, fixtures and assemblies. Integrating the instruments into a production control loop yields immediate rational benefits: faster throughput, reliable digital documentation and fewer rework cycles, while the compact form factor supports both bench and in‑line quality checks.

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.

FAQ
What accuracy can I expect from digital three-point inside micrometers?
Digital three-point inside micrometers typically deliver an accuracy of ±2 µm and a resolution of 0.001 mm, which is suitable for fine tolerance work in precision engineering.
Can these micrometers measure deep or stepped bores?
Yes. Three-point inside micrometers are specifically designed for bores and through holes; extensions and exchangeable jaws allow measurements in deep or stepped bores, with extension lengths such as 100 mm and 150 mm available.
Which data interfaces are supported by the digital models?
Digital three-point inside micrometers commonly support Bluetooth, USB, RS‑232 and Wi‑Fi, enabling both direct measurement readout and integration into data acquisition systems.
Are there space-saving versions for tight access?
Compact rod-style three-point inside micrometers are made for confined spaces, while pistol-grip versions provide ergonomic advantages for repetitive measurements.
