TT 160, TT 460
TT 160 and TT 460 are tactile measuring probes from HEIDENHAIN designed for precise tool measurement and condition monitoring (for drilling and milling tools) directly on the machine. Tool measurement can be performed at any time: before machining, between machining steps, or after the process is complete.
Application examples:
- Cycle-controlled tool inspection
- Tool presetting
- Inspection of individual cutting edges
Benefits:
- Fully automated tool breakage inspection
- In-process tool measurement
- Easy installation and commissioning
- Flexible mounting with the wireless TT 460 probe
- Automatic calibration after installation or maintenance
- Safety break point protects both the probe and the spindle
- Exceptionally robust design with long service life (over 50 million cycles)

TT 160
- Exceptional probing repeatability (2σ ≤ 1 µm) for superior measurement quality
- Signal transmission via cable
- Protection rating: IP68
- Interfaces: HTL (compatible with TD 110 tool breakage detector)
TT 460
- High probing repeatability for excellent measurement quality
- Signal transmission: radio or infrared
- Interfaces: HTL or EnDat 2.2 via SE (interface unit)
- Protection rating: IP68
