Import Tips & Compliance
• Provide CAD drawings and spindle compatibility certs; pitfall is classifying as unfinished without proof of insert-holding function
• Ensure labeling specifies 'for replaceable inserts' to distinguish from solid drill holders
• For high-speed versions, include balance grade G2.5 documentation to support valuation
