Spi CMS160712099 Groove Micrometer Mechanical

Product Description

The SPI CMS160712099 is a mechanical groove micrometer designed for precision measurement in tight or recessed features such as grooves, slots, and undercuts. It measures inside dimensions from 0.06 to 1.05 inches and outside dimensions from 0 to 1 inch, with a graduation and accuracy of 0.001 inches. The carbide anvil and carbide spindle resist wear during repeated use in production and inspection environments. A 6.5mm measuring disc diameter allows access to narrow groove profiles. This tool is calibrated and ships with a Short Form Certificate of Calibration traceable to NIST standards, making it suitable for quality-controlled shops and metrology applications.

The CMS160712099 is used in machine shops, manufacturing facilities, and precision inspection environments where groove, undercut, and recessed-feature measurement is required. The non-rotating spindle design minimizes contact-surface drag during measurement, improving repeatability. A reach length of 1.4 inches allows access to moderately deep features. Typical users include machinists, quality control technicians, and tool and die professionals working to close tolerances on turned, milled, or ground components.

Key Features

• Inside measurement range: 0.06 to 1.05 inches
• Outside measurement range: 0 to 1 inch
• 0.001-inch graduation and 0.001-inch accuracy for high-precision work
• Carbide anvil and carbide spindle for extended wear resistance
• Non-rotating spindle reduces surface drag and improves repeatability
• NIST-traceable calibration certificate included
• Chrome finish with 6.5mm measuring disc diameter for groove access

Compatibility

Designed for general-purpose groove and undercut measurement on machined components where inside or outside dimensions fall within the stated ranges of this instrument.

Installation Notes

This instrument requires no installation; it is a handheld precision measuring tool. Before use, verify the zero setting against the included calibration reference and inspect the carbide contacts for nicks or wear. Store in the included case when not in use to protect the spindle and anvil surfaces. Calibration should be verified periodically per your facility quality plan or applicable metrology standards.
