Mitutoyo 368-876 Holtest Type II Internal Micrometer 6-7 Inch Range

The Mitutoyo 368-876 Holtest Type II is a precision internal micrometer designed for accurate bore measurement in the 6-7 inch range. This three-point contact bore gauge delivers reliable measurements with a resolution of 0.0002 inches, making it ideal for quality control and inspection applications requiring exceptional accuracy.

Key Features:

• Measuring range: 6-7 inches with 0.0002 inch graduation
• Three-point contact design with alloyed steel contact points for enhanced stability and wear resistance
• Self-centering mechanism ensures consistent, accurate measurements
• Ratchet stop provides constant measuring force for repeatable results
• Compact head design allows measurement closer to the bottom of blind bores
• Type II configuration optimized for mid-range bore diameters

The Holtest's three-point contact system automatically centers the tool in the bore, eliminating alignment errors common with two-point micrometers. The integrated ratchet stop ensures uniform contact pressure across multiple measurements, reducing operator influence and improving measurement consistency. The rugged alloyed steel contact points provide long-term durability in production environments.
