DEFINITION

Classification: 175/343

(under subclass 331) Apparatus in which (1) the rolling cutter element is mounted on an axis which is spaced from, or inclined to the geometric axis of the cutter or cutting edge, or (2) in which the rolling cutter element is loosely held on its rotary supporting means so that it may continually shift laterally as it rolls.

(1) Note. The loosely supported cutters are usually disks which slide on part of the bit head to effect a

self-sharpening function.
