Product catalog summary
Standard Drilling Conditions Summary

Specifications:
The document outlines standard drilling conditions, including rotational speeds (RPM) and feed rates (mm/min) for a variety of materials such as structural steels, carbon steels, alloy steels, pre-hardened steels, stainless steels, mold steels, cast iron, aluminum alloys, copper alloys, nickel alloys, and titanium alloys. These specifications are detailed in a comprehensive table.

Procedures:
  • Adjust drilling conditions based on machine rigidity and work clamp state.
  • Use water-soluble cutting fluid for the specified table values.
  • Ensure adequate cutting fluid supply to the cutting point and flute.
  • For holes deeper than 3D, reduce RPM and feed speeds by 20% and use step feed, returning to the entrance hole after each step.
  • Always use step feeding for stainless steel, with intervals of 0.5 to 1 × D, or 0.2 to 0.5 × D for small diameters.
  • Use a collet chuck or milling chuck for stability.

Warnings:
  • Adjust conditions based on machine rigidity and workpiece shape.
  • If using non-water-soluble cutting fluid, reduce RPM and feed speed by 20%.
  • Ensure adequate cutting fluid supply.
  • For deep holes, reduce RPM and feed speed by 20% and use step feeding.
  • Step feeding is necessary for stainless steel.
  • Return to the entrance hole during step feeding.
  • Use appropriate chucks for stability.

Additional Notes:
Drills may show discoloration, which does not affect performance. The document also includes drill codes, diameters, lengths, and prices, indicating standard stock items.

Recommendations:
  • Use step drilling for stainless steel to improve chip removal.
  • Discoloration on drills does not affect performance.

Stock and Contact Information:
Standard stock items are available. For pricing and stock inquiries, contact local sales offices or distributors. Contact details for various regional offices are provided for further assistance.

Drilling Conditions Table:
The document includes detailed tables with RPM and feed speed recommendations for various materials and drill diameters.
