(under subclass 186) Device including a work-contacting structure adapted to penetrate the work-surface at a point which has not been previously modified.
(1) Note. The device of this subclass is not to be confused with the device of Class 83, Cutting, or the device of Class 72, Metal Deforming. To be placed herein, the penetrating means must be disclosed solely as means facilitating the securing or aligning of a cutting instrumentality relative to the work and the depression formed must be unused at any other time for any other purpose.
