Mitutoyo 527-101 Vernier Depth Gage 150mm Range

Product Description

The MITUTOYO 527-101 is a vernier depth gage designed for precise depth, step, and slot measurements in machining, fabrication, and inspection environments. It reads to a graduation of 0.02mm with an accuracy of 0.03mm, making it suitable for quality-control work where tight tolerances matter. The gage features a 260mm rule length and a 100mm base, constructed from stainless steel with a satin chrome coating that resists corrosion and reduces glare during use. Licensed machinists, tool and die makers, and metrology technicians are the primary users of this instrument.

The 527-101 is used in residential and commercial machine shops, manufacturing facilities, and inspection departments wherever depth measurements in the metric range are required. The 150mm measurement range covers a wide variety of common depth-check tasks including blind holes, counterbores, and shoulders. The 100mm base provides a stable reference surface across wider workpiece openings, and the satin chrome finish keeps the scale readable under shop lighting conditions.

Key Features

• 0.02mm vernier graduation for fine metric resolution
• Accuracy to 0.03mm for quality-control and inspection use
• 260mm rule length accommodates a wide range of depth measurements
• 100mm base length provides stable contact across wider surfaces
• Stainless steel construction with satin chrome coating for corrosion resistance and readability
• No hook included — suited for standard flat-bottom depth measurement applications

Compatibility

Designed as a direct-use metric vernier depth gage for general machining and inspection applications requiring 0 to 150mm depth measurement range.

Installation Notes

Depth gages of this type are used by machinists and quality-control technicians and require no power source or installation. Before use, clean the base and rule contact surfaces with a lint-free cloth to prevent measurement error from burrs or debris. Store the instrument in its case when not in use to protect the rule and vernier scale from damage. Calibrate or verify the zero setting against a reference surface before beginning a measurement session.
