The Outside Depth Gauges Collection is specifically designed for accurately measuring the depth of slots, holes, recesses, and grooves. Built with hardened materials, stable bases, and finely graduated scales, these gauges provide dependable results in both workshop and industrial environments. They are essential tools for machinists, toolmakers, and engineers who need reliable depth verification in precision machining tasks. Their simple operation and rugged design make them suitable for repetitive use, while their high accuracy ensures confidence in critical measurements. Whether in manufacturing, quality control, or engineering inspection, these depth gauges offer the perfect balance of reliability and precision.

Frequently Asked Questions

Outside depth micrometers are specifically designed with a flat base and interchangeable rods to measure the depth of holes, slots, and recesses with high resolution. By utilizing a ratcheting mechanism, they ensure a consistent measuring force is applied, which is critical for achieving repeatable and accurate results in precision engineering.

The collection features versatile sets, such as the Mitutoyo 129-116, which include multiple sub-rods (e.g., 0-150mm). These rods can be easily swapped out to extend the measuring capacity of a single micrometer head, allowing a technician to measure various depths without needing several individual tools.

Digital models offer a large, clear LCD screen that provides an instant reading, significantly reducing the risk of human error associated with interpreting vernier scales. Many digital versions also feature a "Hold" function and the ability to toggle between metric and imperial units at the touch of a button.

The hardened and micro-lapped base provides a perfectly flat reference surface that sits across the opening of the part being measured. This stability is essential for ensuring the measuring rod remains perpendicular to the workpiece, preventing slanted readings that could compromise quality control.

Yes, the instruments in this collection particularly those from Mitutoyo are built with high-grade stainless steel and often feature IP65-rated protection. This ensures they remain resistant to coolants, dust, and oil, maintaining their accuracy even in demanding machining and manufacturing settings.

HK Calibrations provides professional calibration services traceable to national standards for all depth micrometers and gauges. This service verifies that the base remains flat and the rods are true to their specified lengths, ensuring total operational confidence for ISO-compliant facilities.
