Bit for the core drilling of nonmetals

Abstract

© 2015, Allerton Press, Inc. The design of tools for core drilling is considered, along with their applicability. The deficiencies of existing designs when machining composites and wood are analyzed, including flaking and scratching on the machined surface. A tool design with group teeth is proposed. This design effectively cuts fibers and permits chip removal. A benefit of the new tool design is improved quality of the machined surface.
