SKU CH-6N9A-7RSKK

  • Drills large 1-23/64 inch holes in a single pass
  • 1/2 inch reduced shank fits standard drill chucks securely
  • High-speed steel construction resists heat during heavy cutting
  • Silver and Deming design enables deep-hole drilling up to 3 inch flute length

1-23/64 inch HSS drill bit for heavy-duty drilling

This Drill America bit is made from high-speed steel with surface-treated flutes for wear resistance. Its 1/2 inch reduced shank fits standard drill chucks while allowing large-diameter holes. The Silver and Deming style suits metalworking shops and maintenance crews needing a single large hole size. It is not for users who need a full set of incremental diameters.

Sustained cutting with silver and deming geometry

The 3 inch flute length and 6 inch overall length give room for chip evacuation during deep holes. High-speed steel construction maintains hardness when heat builds up in prolonged cuts. Surface-treated flutes reduce friction so the bit runs cooler under continuous feed. It is not for high-volume production runs that demand cobalt or carbide tooling.

Questions about this item

How hot does the 1-23/64in HSS bit get when drilling steel all day?

High-speed steel dissipates heat well; use cutting fluid and moderate feed rates to keep the 1.3594in cutting edges from overheating during extended runs.

What chuck size must my drill already have to accept the 1/2in reduced shank?

A 1/2in or larger drill chuck is required; the reduced shank fits directly without an adapter.
