What is a Tool Setter?
If a touch probe is your machine’s “sense of touch” for the part, a tool setter is the machine’s “sense of touch (or sight)” for the tool.
A tool setter (also called an on-machine tool measuring system, tool touch probe, or tool presetter) is a device installed inside a CNC machine that measures cutting tool geometry—primarily length (Z) and often diameter/radius (X/Y) and then updates tool offsets automatically. Many tool setters also support broken tool detection and tool-condition checks so the machine can stop, alarm, or switch to a sister tool before scrap happens.
What is a Touch Probe?
If you’ve ever watched a CNC machine “tap” a part a few times before machining—or pause mid-cycle to check a bore—you’ve seen probing in action. A touch probe (often called a workpiece probe) is a high-precision sensor mounted in the spindle (or turret) that touches the workpiece with a stylus ball to capture real 3D coordinates inside the machine, then feeds that data back to the CNC so it can set work offsets, align the part, compensate drift, or verify dimensions in-cycle.

In the field of precision manufacturing, precision and efficiency are always the core drivers for corporate competitiveness. As the “first line of defense” in machining, tool setting stability directly determines the success of the entire production chain.
Tool Setter & Touch Probe: What’s the Difference
We often talk about probes and tool setters like they’re interchangeable, or think everyone inherently knows the difference. But on the shop floor, that assumption can lead to confusion — especially when you’re trying to automate setups, reduce scrap, or move toward lights-out machining.
