This is hands-on shop work — mounting cutters on grinding machines, dressing wheels, checking clearance angles with optical comparators and micrometers, hand-filing burrs — and none of that is text or screen work an LLM touches. The real threat isn't AI but CNC tool-and-cutter grinders and automated resharpening cells that already handle repeat geometries at volume, plus disposable carbide inserts that eliminate resharpening entirely. Employment is small (about 5,600) and has been shrinking for years; the surviving tier is the grinder who can set up and program a 5-axis CNC grinder and handle one-off, custom, or damaged tooling that no automated cycle covers.
Mixed — a routine tier and a judgment tier. Regrinding a standard end mill or hob to a fixed geometry is already a CNC cycle on a Walter or ANCA machine, but chasing a chipped form tool with no print, deciding whether a burned edge can be saved, and blending a relief by hand on a pedestal grinder still needs a person at the wheel — mixed, and the split is roughly by batch size.
Hands-on in uncontrolled environments. You are physically indexing cutters in fixtures, dressing and truing wheels, feeling for chatter, breathing coolant mist and abrasive dust, and hand-filing burrs on parts you hold — an uncontrolled shop floor, though it stops short of 18-20 because the work sits at a machine in one bay rather than on a moving jobsite.
No licence, no signature requirement. No state licence, no board, no certification anyone asks for at hire; a machinist card or an employer's in-house sign-off is the whole credential, and a tool that fails in service is the shop's warranty problem, not yours personally.
Anonymous artifact production. The customer receives a resharpened cutter in a box and measures it; a long-running relationship with a local cutter-grinding shop is real but survives on turnaround and hitting the drawing, and a plant will requote to a competitor over price.
Meaningful discretion. You decide stock removal, wheel grit, and whether a worn cutter is scrap or salvageable, which is genuine discretion on a one-off — but for the bulk of the work the print, the manufacturer's angles, and the comparator overlay tell you what right looks like.
