Description: |
| Follow-up to his previous patent (503225), concerning a Forstner type bit. The primary purpose of this patent was to improve the means for extending the cutter beyond the circular cutting rim, making it more suitable for cutting rosettes. Aspects of both patents were incorporated into his subsequent device for ornamental work, including rosettes (533855). |
