Mitutoyo 128-106 Mechanical Depth Micrometer 1 in 4 in Base

Product Description

The MITUTOYO 128-106 is a mechanical depth micrometer designed for precise depth measurement in machining, tooling, and inspection applications. It features a 1-inch maximum measurement range and a ratchet stop thimble that delivers consistent measuring pressure for repeatable readings. The non-rotating rod design keeps the measuring face stable during contact, reducing the chance of reading error. With a graduation of 0.001 inches and an accuracy of 3 micrometers, this instrument is suited for quality control work and dimensional verification on the shop floor or in a metrology environment.

The 128-106 is used in manufacturing, machine shops, and precision measurement settings where depth, shoulder, and slot dimensions need to be verified to close tolerances. The 4-inch base length provides a stable reference surface across wider workpieces. The satin chrome finish reduces glare under shop lighting. A measuring rod clamp locks the rod in position during transfer measurements. This model ships with 1 rod covering the full 1-inch range.

Key Features

• 1-inch measurement range with 0.001-inch graduation for fine depth readings
• Non-rotating rod maintains consistent contact with the measuring surface
• Ratchet stop thimble provides uniform measuring pressure for repeatable results
• 4-inch base length offers a broad, stable reference platform
• Measuring rod clamp locks rod position during transfer or recording
• Hardened steel measuring face resists wear under regular shop use
• Satin chrome finish minimizes glare and corrosion on exposed surfaces

Compatibility

Designed as a standard mechanical depth micrometer for use in general precision measurement applications. Verify thread and rod specifications before substituting rods from other depth micrometer sets.

Installation Notes

Depth micrometers are typically used by machinists, toolmakers, and quality control technicians. Before use, clean the base and measuring rod with a lint-free cloth and verify the zero setting against a reference flat. Store the instrument in its case when not in use to protect the measuring faces and prevent calibration drift. Do not overtighten the rod clamp, as this can affect rod alignment and measurement accuracy.
