upon the surface of the material with an abradant; (See Search
Notes below for specific class reference.);

substance, classifiable in the class for Solid Material Comminution
or Disintegration. (See Search Notes below for specific class
reference.) Class 125 includes some patents for working stone or

(6A) The class for Tool Driving or Impacting provides for
subject matter directed to driving or impacting a tool, when such
subject matter includes combined features peculiar to tool driving,
but which does not include features limiting the subject matter

has not been cleared as to subject matter in conflict with this
line. (See Search Notes below for specific class reference.)

of a cylinder provided with a series of separate retractable diamond
tools each of which is capable of being rigidly locked.
