DEFINITION

Classification: 83/879

Scoring:

(under subclass 861) Method or apparatus including use of a tool to incise work (without removing material) by either (a) penetration of a nonthickness surface, but to a depth insufficient to reach an opposite nonthickness surface, or (b) penetration of a thickness surface only to a depth insufficient to produce a lamina.

(1) Note. Annually scoring of a workpiece preparatory to breaking a hole therethrough is included in this subclass.
