Value Collection 6612-0010 Inside Dial Caliper Gage

Product Description

The VALUE COLLECTION 6612-0010 is an inside dial caliper gage designed to measure internal diameters and bores with a measurement range of 0.75 inches to 1.75 inches. The dial reads in 0.001-inch graduations with an accuracy of 0.0015 inches, making it suitable for precision work in machining, maintenance, and quality control environments. Ball-type contact points allow the gage to seat cleanly against curved internal surfaces. The 3.25-inch leg length provides reach into standard bore depths. This tool is used by machinists, tool-and-die workers, maintenance technicians, and inspection personnel working with precision-fit components.

This inside dial caliper gage is suited for shop-floor and inspection use where internal bore measurements must be taken quickly and repeatedly. Typical applications include verifying bore diameters on machined housings, pipe fittings, valve bodies, and similar components. The 0.001-inch graduation makes it practical for general-tolerance work without the setup time required by bore micrometers. It is appropriate for both production-line checks and field maintenance situations where a portable, self-contained measuring tool is needed.

Key Features

• Measurement range: 0.75 inches to 1.75 inches for internal diameters
• 0.001-inch dial graduation for direct, easy-to-read measurements
• Accuracy of 0.0015 inches for reliable precision in general-tolerance applications
• Ball-type contact points seat consistently against curved bore surfaces
• 3.25-inch leg length provides reach into standard-depth bores
• Multi-material construction: aluminum alloy, copper alloy, and steel components with black oxide and chrome-plated finish

Compatibility

Designed as a general-purpose inside dial caliper gage suitable for measuring internal diameters in the 0.75-inch to 1.75-inch range across machining, maintenance, and inspection applications.

Installation Notes

This is a hand-held precision measuring instrument and does not require installation. Before use, zero the dial indicator at a known reference standard or setting ring to confirm calibration. Keep contact points clean and free of chips or debris to maintain measurement accuracy. Store in a protective case away from moisture and extreme temperature changes to preserve the finish and calibration.
