Depth Micrometer - Metric

The Metric Depth Micrometer Set is a high-precision measuring tool engineered for machinist, toolmaker, and quality control applications. Built for accurate measurement of blind holes, slots, recesses, and keyways, this micrometer features a integrated ratchet thimble that applies consistent, repeatable contact pressure for highly reliable readings every time.

Key Features

• Ratchet Thimble / Stop: Features a built-in ratchet mechanism that ensures uniform measuring force, preventing over-tightening and eliminating operator variation for maximum measurement repeatability.
• Interchangeable Measuring Rods: Supplied with a set of precision-ground interchangeable measuring rods.
• Hardened & Micro-Lapped Base: The ground and lapped reference base sits completely flat against surfaces to form a reliable datum plane for accurate gauging.
• High-Contrast Laser Markings: Clear, easy-to-read graduations down to 0.01mm etched into a satin-chrome sleeve and thimble to reduce glare in brightly lit workshop environments.
• Spindle Lock: Equipped with a positive locking clamp to hold the spindle securely in place for easy reading retention or transferring measurements.
• Protective Storage Case: Supplied in a fitted wood or hard-shell case to keep the micrometer body, adjusting spanner, and interchangeable rods protected from dust and damage when not in use.
