Starrett T216XRL-3 Mechanical Digital Outside Micrometer 2-3" Range .0001" Graduation

The Starrett T216XRL-3 is a mechanical digital outside micrometer covering a 2–3 inch (50–75mm) measuring range with .0001" graduations and +/- .0001" accuracy. Part of Starrett's trusted 216 Series, this micrometer uses a mechanical digit counter that makes readings intuitive and straightforward, even for less experienced users.

The micrometer reads .001" directly from the counter, while the vernier scale on the thimble and sleeve provides resolution down to .0001". The combination ratchet and speeder thimble delivers uniform measuring pressure and faster spindle adjustment, while the ring-type knurled lock nut ensures quick, secure locking at any setting.
