The INSIZE 3129-10 Snap-Open Digital Three Points Bore Gauge is a precision digital internal measuring instrument designed for accurate measurement of 8–10 mm internal bore diameters. Its three-point measuring system provides stable contact inside suitable cylindrical bores, while the Snap-Open mechanism allows quick engagement and withdrawal for efficient repetitive inspection. The 3129-10 features 0.001 mm resolution, 4 µm accuracy, a digital display, and Type A steel measuring contacts. Its digital data-output capability makes it suitable for CNC machining, production inspection, quality control, tool rooms, and industrial metrology applications.
Key Features
1. 8–10mm Measuring Range
The 3129-10 is designed for measuring internal diameters from 8 to 10 mm, making it suitable for small precision bores, holes, cylindrical components, and machined parts. INSIZE specifies 4 µm accuracy for this range.
2. Digital Three-Point Measuring System
The three-point configuration provides multiple contact points inside the bore, helping establish a stable measuring position for internal-diameter inspection. This makes the instrument suitable for precision machining and quality-control applications.
3. Snap-Open Mechanism
The Snap-Open mechanism allows the measuring contacts to retract quickly, making insertion and removal faster during repetitive measurements. This can be particularly useful in production environments where inspection speed and repeatability are important.
4. 0.001mm Digital Resolution
The 3129-10 provides 0.001 mm resolution, allowing detailed digital readings for precision dimensional inspection. Current product information also lists adjustable resolution options of 0.001 mm / 0.0005 mm.
5. Digital Connectivity & Industrial Protection
The 3129-10 is listed with Bluetooth and USB Type-C data output and IP54 protection, supporting digital measurement-data collection and use in industrial environments.
