Ultra-small touch probe [K3S series]

The probe body is thinner than prior versions!

The ultra-small touch probes “K3S Series” can easily be mounted even in tiny limited spaces.
Unlike conventional touch probes, the main body is not exposed, so it does not interfere with the spindle or workpiece and does not take up extra space in other tool holders.
Please see case studies of K3S series

The K3S Series has a wide range of customizable options for mounted devices.
