Mitutoyo 983532 Depth Micrometer Rod 9 to 10 Inches

Product Description

The MITUTOYO 983532 is a replacement depth micrometer rod designed for use with Mitutoyo 135 and 329 series depth micrometers. It extends the measurement range of compatible depth mics to cover depths from 9 to 10 inches. The rod measures 4.00 millimeters in diameter and has an overall length of 332.90 millimeters (approximately 13.11 inches). Machined to close tolerances, it maintains the accuracy expected from precision metrology tooling. This rod is the correct accessory when a worn or missing rod needs to be replaced to restore a depth micrometer to full working condition. It is used in machine shops, manufacturing facilities, and maintenance environments wherever precise depth measurement is required.

This rod is intended for professional use with Mitutoyo 135 and 329 series depth micrometers. It fits the standard rod-change mechanism on those instruments and allows the user to measure workpiece depths in the 9 to 10 inch range. Typical applications include checking bores, recesses, slots, and counterbores on machined parts. Machinists, quality control technicians, and tool-and-die professionals are the primary users of this accessory.

Installation Notes

Rod replacement on depth micrometers should be performed by a qualified machinist or metrology technician. Before swapping rods, ensure the instrument is clean and the spindle and anvil faces are free of debris. Follow the micrometer manufacturer's rod-change procedure to seat the rod correctly and avoid damaging the locking mechanism. After installation, verify calibration against a known reference standard before returning the instrument to service.
