Protect your probe from X, Y, and Z axis collisions- over travels that used to crash the probe into your part instead now bump the halo and alarm the machine, just like it would if the stylus detected an unexpected surface. Hit reset, and carry on with your day. 
 
Save the stress, save money, save machine downtime, and run harder and faster knowing that the Probe Halo has got you protected.
 
this is sized to fit renishaw OMP-60 probe with any stylus with a .275" shank (the standard size).
 
This item always ships free.
