Depth Steps

Whistle style steps are ground on the Go gauge member of a pin or plug gauge to give an economic solution for checking the depth of blind holes, stepped holes and counter-bores. Go and No Go depth steps can be ground on the same gauge member.

Gauge life and dimensional stability are guaranteed based on well proven manufacturing processes and a robust quality management system.


  • Extended length pins or gauge members to accommodate deep holes.
  • Position of steps calculated to accommodate and angled hole.
  • Recessed leading face of the pin to clear protrusion.
