A 23/32 inch high-speed steel drill bit with a 118-degree point and taper shank for general-purpose drilling

  • Product typeDrill Bits
  • 23/32 inch diameter drills large holes accurately
  • 118 degree point angle centres quickly on contact
  • High speed steel resists wear during extended use
  • Black oxide finish reduces friction and corrosion
  • Taper shank seats securely in machine spindles

Taper Shank Drill Bit 23/32 in

This taper shank drill bit measures 23/32 in and features a 118 degree point angle. It is made from high speed steel with a black oxide finish. The conventional point design suits general purpose drilling tasks in a workshop or maintenance setting.

Black oxide finish on high speed steel

The black oxide coating reduces friction and helps resist corrosion during use. High speed steel construction maintains hardness at elevated temperatures. These material choices extend bit life when drilling into ferrous metals and other common workpiece materials.

Direct fit for taper shank holders

The Morse taper shank seats directly into compatible drill presses or lathe tailstocks without an adapter. Ensure the machine spindle matches the taper size before installation. Improper seating or debris in the socket can cause runout or the bit to spin loose under load.

Questions about this item

How often will the 23/32 in high-speed steel bit need resharpening?

Resharpening frequency depends on the material being drilled and feed pressure; the 118-degree conventional point can be reground multiple times before the taper shank length becomes too short for the holder.

What limit appears first when drilling continuously with the 118-degree point?

Heat buildup at the cutting edges is the first limit; sustained high-speed drilling without coolant will dull the high-speed steel faster than the taper shank or black oxide coating wears.

Does the black oxide finish run hotter than a bright finish during all-day use?

Black oxide retains slightly more heat than a bright finish, but the difference is small; using cutting fluid and proper speed for 23/32 in diameter keeps temperatures manageable.
