Mitutoyo 468-987 Digital Holtest Internal Micrometer 0.5-1 Inch Range

The Mitutoyo 468-987 Digital Holtest is a precision internal micrometer designed for accurate measurement of bore diameters, hole sizes, and internal dimensions ranging from 0.5 to 1 inch. This three-point contact bore gauge features advanced digital readout technology for fast, reliable measurements in machine shops, quality control labs, and manufacturing environments.

Key Features:

• TiN (Titanium Nitride) coated measuring contact points deliver exceptional durability and impact resistance while enabling measurements to the bottom of blind holes
• Large, easy-to-read LCD digital display for clear viewing of measurements
• Integrated ratchet stop mechanism ensures consistent measuring force for repeatable accuracy
• Three-point contact design provides stable, accurate bore measurements
• 0.5 to 1 inch (12.7 to 25.4mm) measuring range
• Digital unit set configuration allows for easy zeroing and calibration

The Holtest's three-point contact system automatically centers the instrument in the bore, eliminating alignment errors common with two-point micrometers. The TiN coating significantly extends contact point life, making this tool ideal for high-volume inspection applications and measurements in abrasive or demanding environments.
