Meet the Mitutoyo Digimatic Interchangeable Rod Depth Micrometer, Inch/Metric, 0-6" with 6 rods. This versatile depth micrometer is designed for engineers, machinists, tradespeople, hobbyists, and DIY enthusiasts who need precise depth measurements across a wide range. By swapping in Ø4 mm rods, you can extend reach while preserving accuracy for deep cavities, steps, and grooves.

Included six rods provide flexible setup for a variety of tasks, and the tool features a precision lapped measuring surface to ensure clean, repeatable contact. A ratchet stop delivers constant measuring force for consistent readings, while the rod lock keeps your selected rod secure during measurement.

• Interchangeable Ø4 mm rods for a wide range: Six precision rods extend the measurement range and adapt to different workpieces, while maintaining accurate contact thanks to the lapped surfaces.
• Lapped measuring surfaces for consistent accuracy: The finely finished contact surfaces ensure smooth, repeatable readings across the entire range.
• Ratchet stop with rod lock for reliable setup: Provides constant measuring force to improve repeatability and a secure rod lock to prevent drift during measurement.

This depth micrometer helps you work faster and with greater confidence. The interchangeable rods let you tailor the tool to the task, while the ratchet stop and rod lock minimize measurement drift and fatigue, delivering precise depth readings across a variety of applications—from component inspection to fixture verification.
