Mitutoyo 368-262 Holtest 3-Point Internal Micrometer 0.35-0.425 Inch Range

The Mitutoyo 368-262 Holtest is a precision internal micrometer designed for accurate measurement of bore diameters and internal dimensions. This versatile instrument features both 3-point and 2-point contact configurations for maximum measurement flexibility across a range of 0.35 to 0.425 inches.

Key Features:

• Measurement range: 0.35 to 0.425 inches
• High accuracy: ±0.0001 inch tolerance
• Dual measurement modes: 3-point and 2-point contact configurations
• TiN-coated (Titanium Nitride) contact points for enhanced wear resistance and extended tool life
• Carbide-tipped contact points provide exceptional durability in demanding applications
• Compatible with optional setting rings for precise zero-point adjustments

The Holtest design ensures self-centering measurement capability, eliminating alignment errors common with traditional bore micrometers. The TiN coating on contact points reduces friction and prevents premature wear, making this tool ideal for production environments and quality control applications requiring repeatable, high-precision internal measurements.
