Starrett T436.1XRL-11 Outside Micrometer 10-11 in

Precision Range for Large Parts

The Starrett T436.1XRL-11 is a mechanical outside micrometer covering a 10 in to 11 in range, equivalent to 75 mm to 100 mm. It serves machinists and inspectors who need verified readings on large shafts, plates or bearing journals. A vernier scale provides a 0.0001 in resolution with a stated accuracy of +/- 0.0001 in. The steel frame and carbide-tipped flat anvil resist wear during repetitive use.

Carbide Anvil and Ratchet Thimble

A carbide anvil face maintains flatness longer than hardened steel, reducing the frequency of recalibration. The ratchet thimble applies consistent measuring force, helping different operators achieve repeatable results. An included adjustable wrench allows quick zero adjustment, while the ring lock nut secures the spindle once a reading is taken. A fitted case protects the instrument when not in use.

Simple Mechanical Setup

No power source or software is required; the tool is ready once removed from its case. Clean the anvil and spindle faces before each session to avoid dust-induced errors. Apply the ratchet gently — forcing the spindle can distort the frame and invalidate the 0.0001 in accuracy. Verify zero on a known standard periodically, as the long-form calibration certificate is not supplied.
