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.
