Mitutoyo 468-274 Digimatic Holtest Internal Micrometer 4-5 Inch Range

The Mitutoyo 468-274 Digimatic Holtest is a precision internal micrometer designed for accurate measurement of bores, grooves, and internal diameters from 4 to 5 inches (101.6-127mm). This advanced measuring instrument features a digital LCD display with .00005 inch (0.001mm) resolution and includes SPC (Statistical Process Control) data output capability for quality control applications.

Key Features:

• Measurement range: 4-5 inches / 101.6-127mm
• Resolution: .00005 inch / 0.001mm for ultra-precise measurements
• Titanium Nitride (TiN) coated contact points for exceptional durability and impact resistance
• TiN coating allows measurement to the bottom of blind holes without damage
• Large, easy-to-read LCD digital display
• Ratchet stop mechanism ensures constant measuring force for repeatable results
• SPC data output for integration with quality control systems
• Inch/Metric switchable display

The Holtest design provides three-point contact measurement for superior accuracy when measuring internal dimensions. The ratchet stop guarantees consistent application pressure, eliminating operator variation and improving measurement repeatability. Ideal for precision machining, quality inspection, and manufacturing environments requiring accurate bore measurement.
