Tool Presetter and Tool Setter
A tool presetter measures tool geometry before or outside the cut; an on-machine tool setter measures tools in the machine and can update offsets or detect breakage.
How Tool Presetter and Tool Setter works
- Offline presetters measure assembled tool length and diameter away from the machine to prepare offsets before setup.
- Contact setters physically touch the tool; non-contact systems use an optical beam or other sensing method.
- Measured values can be entered manually or transferred digitally, depending on the equipment and workflow.
- Clean interfaces, spindle/holder condition, calibration and consistent tool assembly are essential to useful data.
What to compare
| Type | Offline presetter, contact setter, laser/non-contact setter or combined workflow. |
|---|---|
| Range | Maximum diameter, length, weight and supported holder interfaces. |
| Data | Label, network, postprocessor and tool-management integration. |
| Performance | Repeatability, calibration method and environmental sensitivity. |
| Protection | Coolant/chip resistance, cleaning cycle and crash protection for on-machine units. |
Used-equipment inspection checklist
Verify the machine
- Repeat-measure a stable tool and review variation.
- Confirm all holder adapters, spindles and calibration artifacts.
- Test data transfer rather than assuming compatibility.
- Inspect optics, stylus, spindle and protective mechanisms.
- Verify software, licenses, computer requirements and support.
Verify the transaction
- Match the serial number and configuration to the seller's description.
- Identify every included and excluded accessory in writing.
- Confirm power, air, coolant, foundation, rigging and relocation requirements.
- Record a time-stamped operating demonstration and measured result.
- Price missing service, software, tooling and recommissioning before comparing offers.
Why this term matters in the used-machine market
Search results and listings often compress a complete production system into one label. Buyers should translate that label into capacity, condition, control generation, included tooling, serviceability and demonstrated output. Sellers improve credibility by disclosing those facts instead of repeating a brochure headline.
Market value is also specific to timing and buyer fit. A capable machine can trade poorly when its configuration is hard to relocate, support or redeploy; a common platform with documented maintenance, current controls and proven output may attract a wider buyer pool.

Frequently asked questions
Is a presetter the same as a probe?
No. A tool setter measures cutting tools; a workpiece probe locates or measures the part and fixture, though both can participate in an integrated setup process.
Does tool presetting eliminate touch-offs?
It can greatly reduce manual setting, but the process still requires calibrated references and a controlled relationship among holder, spindle and machine coordinates.
