Cleveland C96023 Spiral Point Tap 1/2-20 UNF Cobalt 3 Flutes

SKU CH-CZJ1-G35QC

Cuts 1/2-20 UNF threads in tough materials using a cobalt spiral-point plug tap with three flutes and Hard Lube coating

  • Cobalt construction resists heat and wear
  • Spiral-point design pushes chips forward for through-holes
  • Three flutes balance strength and chip clearance
  • Hard Lube coating reduces friction and extends tool life
  • 2B class-of-fit ensures accurate UNF threads

Threading tool for fine-pitch UNF holes

The Cleveland C96023 is a spiral-point tap cut for 1/2-20 UNF threads. Its cobalt body with Hard Lube coating handles tough materials while the right-hand, three-flute design pushes chips ahead of the cut. Machinists and maintenance technicians use it to produce Class 2B internal threads in through-hole applications.

Behaviour in continuous cutting

The spiral-point geometry ejects chips forward, reducing flute clogging during sustained passes. Cobalt construction resists heat buildup when the tap remains engaged for the full 1 17/32 in thread length. Hard Lube coating lowers friction so cutting edges stay sharp longer under repetitive use.

Limits of the UNF 2B standard

The 2B class of fit defines the allowable pitch-diameter tolerance for general-purpose fastening. A 75 percent thread depth based on an 11.40 mm drill size balances strength with tapping torque. The 4 21/64 in overall length reaches standard hole depths but cannot address deeper bores without an extension.

Questions about this item

How much heat does the cobalt tap generate when running all day?

Cobalt steel resists heat buildup better than high-speed steel during extended threading, and the Hard Lube coating further reduces friction.

What drill bit must I already own for the 1/2-20 UNF thread?

A 11.40 mm drill bit is required to produce the 75 percent thread drill size for this tap.

Will the 3-flute spiral point work with my older manual tap wrench?

Yes, the square drive on the 4 21/64 in shank fits standard tap wrenches used with hand threading.
