220XRL-1
Starrett MultiT-Anvil Micrometer

This tool was a new development in micrometer design and patent
is held by Starrett. This micrometer will handle a wide variety of
measurements impossible to obtain with regular micrometers, such as
measuring the wall thickness of tubing, cylindrical walls from a hole
or slot to an edge, many hard-to-reach locations, and the thickness of
screw heads, shoulder lengths, etc.
A most interesting feature of this tool is that additional anvils of various
shapes can be made up, and many of these anvils do not have to be
hardened for that “special job”.
This micrometer can be furnished with .0001" graduations, but we
recommend .001" or 0.01mm for easier and more accurate readings.
The Starrett Company, with our years of experience, recommends this
because the anvils on this type of tool are not backed up by a frame as
in a regular micrometer and could bend slightly.

Ease-of-Handling Features

• Balanced frame and thimble design ensure easy handling, better
  readability
• Ring-type knurled lock nut for quick and sure locking
• A choice of smooth friction thimble for uniform pressure or the
  combination ratchet and speeder for uniform pressure and quicker
  adjustment
• Interchangeable anvils are rigidly held in the vise type frame and
  quickly interchanged by a single lock screw adjustment
• Two hardened anvils furnished – round anvil approximately .120"
  diameter (3mm) and flat anvil approximately .125" (3mm) and
  .060" (1.5mm) thick
• “V” Anvil for measuring thickness of screw heads and shoulder
  lengths available separately
• Accommodates special anvils up to 5/16" (8mm) thick
• Can be used as a height gage by removing the vise jaw
