Chicago-latrobe 57830 Hss Drill Blank Set 80-1 20pc

Product Description

The CHICAGO-LATROBE 57830 is a 20-piece high speed steel drill blank set covering sizes 80 through 1 in a bright (polished) finish. Drill blanks are unfluted, precision-ground rods used as gauge pins, punch blanks, or custom tooling stock. They are a staple in tool-and-die shops, machine shops, and precision fabrication environments where technicians need accurately sized stock ready for grinding or specialty applications. The set ships as a complete numbered series, giving machinists and tool makers a ready reference across the full wire gauge range without sourcing individual blanks.

This set is suited for machine shops, toolrooms, and production environments where wire-gauge-size drill blanks are used regularly for gauging, tooling fabrication, or die work. The bright finish indicates an uncoated, polished surface that provides consistent diameter tolerance across all 20 pieces. The Series 165 designation identifies this as part of the established CHICAGO-LATROBE blank series, commonly stocked in industrial supply and toolroom inventories.

Compatibility

Designed as a standard wire-gauge drill blank set suitable for use in tool-and-die, machining, and precision fabrication applications requiring Series 165 high speed steel blanks in sizes 80 through 1.

Installation Notes

Drill blanks are installed or used by machinists and tool-and-die technicians in controlled shop environments. Ensure all machinery is powered down and locked out before mounting or measuring with blanks. Handle high speed steel blanks with care to avoid nicking or scratching the precision ground surface, which can affect gauge accuracy. Standard shop safety practices and applicable OSHA machine-guarding requirements apply when using blanks in grinding or fabrication operations.
