Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If annular cutter style
Core or annular drill designs for hole saw applications have separate classification.
If for earth moving equipment
Heavy equipment boring tools classify under Chapter 84 for parts of machinery.
If basic non-alloyed large drills
Failure to meet minimum alloy percentages defaults to other rock/non-specified drills.
