  • Standard Compatibility - Fits all indicators made to AGD standards, ensuring wide applicability in various measuring tasks.
  • Secure Clamping - Features a 9.5 mm diameter hole for firm attachment, providing stable and accurate measurements.
  • Versatile Functionality - Designed to measure the inside of holes and other hard-to-reach areas, enhancing measurement capabilities.

These hole attachments make it possible to measure the inside of holes and other surfaces that cannot be reached with the regular indicator spindle. Both attachments have a 0.375" (9.5mm) diameter hole to fit all indicators made to AGD standards and can be securely clamped to the indicator stem. The ball end on the swivel arm which contacts the work is 1/8" (3mm) in diameter.

Pivot is much too tight. I'm going to have to take it apart to do some lapping, see if I can loosen it up. I expect better from Starrett.
