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.
