Subheadings
Products classified under HTS 8459.49.00
CNC Horizontal Boring and Milling Machine
A computer numerical control (CNC) machine designed for precision boring and milling operations on large metal workpieces by removing metal shavings. It features a horizontal spindle and is used in heavy industries like aerospace for machining engine blocks. Classified under HTS 8459.49.00 as an other boring machine not specified elsewhere in the heading.
Vertical Boring Mill for Large Parts
Heavy-duty vertical boring mill used for deep hole boring in large metal components like turbine housings by chip removal. Equipped with a rotating table and fixed spindle for high-precision work in power generation. Falls under HTS 8459.49.00 as other boring machines excluding lathe-types.
Horizontal Tube Boring Machine
Specialized horizontal boring machine for internal machining of metal tubes and pipes by metal removal. Used in oil & gas for barrel rifling and cylinder honing. Classified in HTS 8459.49.00 as other boring machines.
Floor-Type Boring Machine
Robust floor-mounted boring machine for heavy metal removal in large castings and forgings. Features traveling column design for extended reach. HTS 8459.49.00 for other non-lathes boring machines.
Deep Hole Boring Machine
Specialized deep hole boring machine for gun barrels, hydraulic cylinders, and landing gear components via high-pressure coolant metal removal. Capable of bores exceeding 10 meters length. HTS 8459.49.00 classification for other boring types.
Portable Line Boring Machine
Compact portable boring machine for in-situ repair boring of heavy equipment pins and bushings by metal removal. Mounted on-site for excavators and cranes. Still classified under HTS 8459.49.00 as other boring machines.
