Mitutoyo 468-977 Holtest Digital Bore Gauge Head Set 0.5-0.8 Inch

The Mitutoyo 468-977 Holtest digital bore gauge head set is a precision measuring instrument designed for accurate internal diameter measurements from 0.5 to 0.8 inches. This three-point internal micrometer head provides reliable, repeatable measurements for quality control and inspection applications.

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 LCD digital readout for easy reading and reduced measurement errors
• Ratchet stop mechanism ensures consistent measuring force for repeatable results
• Measurement range: 0.5 to 0.8 inches (12.7 to 20.3mm)
• Three-point contact design provides stable, accurate bore measurements

This Holtest head set is ideal for measuring cylinder bores, bearing housings, and other precision internal diameter applications in manufacturing and inspection environments. The digital display eliminates parallax reading errors common with analog instruments.
