Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If without any diamond content in the working elements
Tungsten carbide or other material reamers fall in the residual other rock boring tools.
If constructed primarily as diamond-set concrete structures
Articles of cement with embedded diamonds classify under Chapter 68.
If when used as hammer drill bits for handheld power tools
Handtool-specific diamond bits shift to Chapter 82 handtool heading.
