TD 110 Tool Breakage Detector


The TD 110 Tool Breakage Detector provides contact-free inspection of drill bits and end mills, determining whether a tool is broken off by more than 0.08 in. (2 mm) as it passes within a machine tool. The breakage sensor can be placed in the work envelope for it to be fast and easy to reach during the tool change. The inductive sensor can detect tools as they pass by while they are spinning at their operational speed. Even very small tools made of HSS steel and carbide are detected with its rapid scanning technology.


The breakage sensor can then generate either a floating or an HTL switching signal, and the machine control can evaluate it via standard instruction sets.  These signals/outputs can be used to connect to a HEIDENHAIN TNC control or a PLC or to any other IOs of nearly every CNC control manufacturer. In addition, an LED signals whether a tool has been flagged.


  • Maintenance-free sensor for reducing non-productive time for breakage inspection
  • Cooling lubricant and lightly contaminated tools are tolerated
  • Universally retrofittable thanks to standard interfaces for tool touch probes
