High-Speed Steel End Mill
A milling cutter with a cutting edge made from high-speed steel alloy containing over 0.2% chromium, molybdenum, and tungsten, designed for interchangeable use in CNC machine tools. It excels in high-speed machining of metals due to its heat-resistant properties. Classified under 8207.90.30 for its alloy composition exceeding the specified elemental thresholds.

More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If cutting part has 0.2% or less Cr/Mo/W and 0.1% or less V
Lower alloy content shifts to the general 'other cutting tools' subheading without high alloy specs.
If designed primarily for handheld power tools like drills
Handtool-specific bits fall under Chapter 82 heading for drill bits, not machine-tool interchangeables.
If imported as a complete assembled machine-tool spindle
Machinery parts beyond just the interchangeable tool are classified in Chapter 84.

Import Tips & Compliance
• Provide material composition certificates from manufacturer verifying Cr/Mo/W/V content to avoid reclassification
• Ensure tools are marked as 'interchangeable for machine-tools' to distinguish from handtools
