The BORLETTI digital calipers for internal grooves are professional measuring instruments designed to perform precise and reliable measurements on internal surfaces, internal grooves, and mechanical cavities. Made entirely of stainless steel, these calipers offer durability, dimensional stability, and corrosion resistance, making them ideal for daily use in workshops, metrology laboratories, production plants, and industrial environments exposed to dust, humidity, or mechanical stress. The presence of ground jaws ensures clean and accurate contact for every measurement.

 

The high-visibility LCD display with clear digits enables easy reading even in low light or busy industrial settings. The top locking screw system allows the slider to be fixed in position, while the bottom adjustment wheel ensures smooth and controlled advancement. These instruments offer a resolution of 0.01 mm and an accuracy of 0.02 mm.

 

The IP54 protection ensures safety against dust and water splashes, enhancing the tool’s reliability even in harsh environments. The protective label on the graduated beam guards against wear and contamination. The integrated digital functions include ON/OFF, mm/inch conversion, ABS/INC mode, and zeroing function, useful for switching from absolute to incremental measurement, setting temporary zeros, and working in both metric and imperial units. The data output allows connection to data collection software or quality control systems, making the calipers compatible with modern traceability and digitalization requirements in production environments.

 

These calipers for internal grooves are essential tools for CNC operators, lab technicians, engineers, and dimensional inspection personnel. Thanks to their combination of high precision, mechanical strength, and versatility, they represent a technical benchmark solution for professional measurement in mechanical, aerospace, automotive, and manufacturing sectors. Their reliability and BORLETTI build quality make them a secure investment for those who demand repeatable and consistent measurements over time, even in challenging operational conditions.
