Use these attachments to mount indicators in chucks, tool posts, height gauges, or a variety of other setups.

Install these attachments onto Starrett magnetic-base holders for more precise control over positioning.

Adjust the flexible arm to nearly any position.

Use a swivel clamp to attach an indicator to the positioning arm.

The base is comprised of adjustable magnetic pins which allow it to conform to any shape and grip most metal surfaces.

Attach the C-clamp on these holders to your milling machine head to take indicator measurements without obstructing the cutting tool.

Adjust the flexible arm to nearly any position.

These holders come with a calibration certificate traceable to NIST states that the granite base has passed a test for surface accuracy. The extremely tight flatness tolerances of the granite allow for nearly frictionless workpiece movement and provide an accurate reference plane for inspection work.

Vise-grip locking pliers clamp these holders to most thin, flat surfaces, and the flexible arm lets you position your indicator around obstructions.
