■ CRITICAL RISK ■ Manufacturing & Production
For the machine-tending version of this job, yes — CNC drilling centers and robotic loading have been replacing manual drill press operators for decades and AI is mopping up the remainder. The future belongs to people who program and maintain the drills, not the ones who feed them.

Our AI replacement risk score — how we score jobs
A drilling machine operator's shift revolves around holes: reading the job traveler and blueprint, selecting and mounting the right bit, fixturing the workpiece, setting speeds and feeds for the material, running the cycle, and checking hole diameter, depth, and position with gauges and calipers. On manual drill presses the operator does everything by hand and feel; in more modern shops the 'operator' loads parts into a CNC drilling or machining center, presses cycle start, and watches for broken tools and chip buildup while parts accumulate.
That evolution is the whole story. CNC eliminated the skill of guiding the drill; the coordinates live in the program, and positional accuracy stopped depending on human steadiness a generation ago. What's automating now is the remaining human residue: robotic arms and pallet systems load and unload parts, tool-monitoring sensors detect a dulling or snapped bit faster than an ear can, in-process probing verifies hole dimensions without anyone lifting a caliper, and lights-out machining lets the equipment run overnight with nobody on the floor. One attendant now covers a cell of machines that once each had an operator.
Resistance comes from economics and oddball work, not from any protected skill. Low-volume job shops running one-off repairs can't justify robotic loading for a five-part order, so a human with a drill press stays cheaper. Awkward, heavy, or weird-shaped workpieces resist standard fixturing. And every automated cell still needs setup people who can fixture a new job, prove out a program, and diagnose why holes are suddenly oversize — spindle runout, worn bushing, wrong coolant. Those setup and troubleshooting roles are the lifeboat; simple operation is the part going under, which is what an 89 risk score means.
Automatability: our editorial assessment of current and near-term AI capability
This is late-stage automation, not early warning. CNC removed the craft decades ago; robotic part loading, tool-condition sensors, and in-process probing are removing the babysitting now. Shops that invest run drilling cells overnight with no one present, and each capital upgrade this decade converts several operator jobs into a fraction of one technician job. Manual drill press work persists only in small job shops with low volumes.
As pure operators, a short one. Loading parts and watching cycles is exactly what robots and monitoring sensors now do. But the machining industry has a genuine shortage of setup technicians, CNC programmers, and maintenance people, and operators who climb into those roles find steady demand. The future is one skilled person per cell instead of one operator per machine.
Enormous. An operator loads parts and starts cycles someone else programmed — that's the automatable layer. A machinist sets up jobs, edits programs, selects tooling, holds tolerances, and troubleshoots quality problems. Shops struggle to hire machinists and are actively automating operators. The certification and skill gap between the two titles is the single best investment someone in this trade can make.
Longer than big plants will. A shop running five-piece repair orders can't amortize robotic loading, so a versatile human at a drill press or manual mill stays economical. But those shops want flexibility — someone who can drill, tap, deburr, inspect, and maybe run the saw — not a single-machine operator. Even in the refuge, the pure-operator role is dissolving into a generalist one.
Blueprint reading and GD&T if they're shaky, then CNC setup: workholding, tool offsets, and proving out programs. Add basic program editing and preventive maintenance. Community college machining programs and manufacturer certifications cover this in months, not years, and shops frequently pay for training because they need setup techs more than they need another set of hands at the load station.
