Mitutoyo 468-277 Digimatic Holtest Internal Micrometer 7-8 Inch Range .0001 Inch Resolution

The Mitutoyo 468-277 Digimatic Holtest is a precision internal micrometer designed for accurate measurement of bore diameters, offering a measurement range of 7-8 inches (177.8-203.2mm) with a resolution of .0001 inch (0.001mm). This advanced bore gauge features digital readout technology and SPC (Statistical Process Control) output capability for seamless data collection and quality control processes.

Key Features:

• TiN (Titanium Nitride) coated measuring contact points deliver exceptional durability and impact resistance while enabling measurement to the bottom of blind holes
• Large LCD display provides clear, easy-to-read measurements in both inch and metric units
• Integrated ratchet stop mechanism ensures consistent measuring force for repeatable, accurate results
• SPC data output allows direct connection to statistical process control systems
• Three-point contact design ensures stable, accurate bore measurements

This Holtest internal micrometer is ideal for precision manufacturing, quality inspection, and tool room applications where accurate bore diameter measurement is critical. The digital display eliminates reading errors common with mechanical dial indicators, while the rugged TiN coating extends tool life in demanding production environments.
