BLS metro-level wage data places Drilling and Boring Machine Tool Setters, Operators, and Tenders, Metal and Plastic pay in Chattanooga, TN-GA at a median of $41,810 per year ($20.10/hr/hour), drawn from the OEWS May 2025 release for this Metropolitan Statistical Area.

The Chattanooga pay distribution spans from $41,060 at the 10th percentile to $46,480 at the 90th — a 1.1× spread that reflects experience tenure, specialization, employer size, and the difference between public-sector, nonprofit, and private-sector compensation inside the metro.

Metro figures capture where you actually work, not just where you live — which matters for commuters. BLS draws metro boundaries from the OMB MSA definitions, so Chattanooga, TN-GA covers the central city plus outlying counties tied to the metro economically. Remember that OEWS wages reflect base pay only: employer-provided health insurance, retirement matches, stock options, signing bonuses, overtime, and tips are excluded and can add 20-40% to real total compensation. Before using this metro median as a negotiation anchor, triangulate against the same occupation's national profile (linked below), its state-wide TN data, and peer-metro comparisons — a median is a starting point, not a ceiling.
