High-Speed Steel Rock Drill Bit
A durable interchangeable rock drilling bit designed for pneumatic or hydraulic rock drills, featuring a cutting edge with high chromium content for extended wear resistance in mining operations. It falls under HTS 8207.19.30.90 due to its classification as a rock drilling tool with cutting part containing over 0.2% chromium by weight, not specified elsewhere. The bit is used in earth boring applications for tunneling and quarrying.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If cutting part has 0.2% or less chromium, molybdenum, or tungsten
Lower alloy content shifts to general 'other' rock drilling tools without high alloy specification.
If sold as complete drilling machine rather than interchangeable tool
Fully assembled earth boring machinery falls under other boring machinery, not individual tools.
If imported as base metal parts without cutting edges
Parts thereof lacking the specified high-alloy cutting part are classified separately.

Import Tips & Compliance
• Verify chemical composition certification for chromium content (>0.2%) to confirm classification and avoid reclassification to lower-duty subheadings
• Provide manufacturer specs and end-use documentation to customs, as rock drilling tools require proof of non-machine-tool primary use
