Cleveland C96109 Spiral Point Tap #8-36 UNF Cobalt 3 Flutes

SKU CH-98DG-36F8J

Cobalt spiral-point tap cuts #8-36 UNF threads with three flutes and a black-oxide finish

  • Spiral-point design clears chips forward for smoother tapping
  • Cobalt construction resists wear in tough materials
  • #8-36 UNF thread fits precise fine-pitch applications
  • Three flutes balance strength and chip evacuation
  • Black oxide finish reduces friction and prevents galling

Cleveland C96109 Spiral Point Tap

The Cleveland C96109 is a spiral point tap designed for creating UNF threads. It features a #8-36 thread size and a cobalt construction with black oxide finish. The plug style tap has three flutes for efficient chip evacuation. It is intended for right-hand threading applications in metalworking.

Suited for through-hole threading

This tap suits machinists producing #8-36 UNF threads in through holes where forward chip ejection is needed. The cobalt material offers wear resistance in steel and tougher alloys. It is not for blind holes where chips must be pulled upward. Buyers needing a different thread size, pitch, or flute count should look at other tooling.

#8-36 UNF thread size decides fit

The single specification that decides whether this is the right part is the #8-36 UNF thread size. The tap cuts a 2B class of fit with a 75 percent thread drill size of #29. Thread length is 53/64 in and overall length is 2 31/64 in. Verify the required thread specification before purchase.

Questions about this item

Does the cobalt material and black oxide finish keep the tap from overheating during extended threading?

Cobalt construction and black oxide coating resist heat buildup and wear, maintaining cutting performance during prolonged use on tough materials.

What drill bit size must I already have to prepare the hole for this #8-36 UNF tap?

A #29 drill bit is required to create the 75 percent thread depth before tapping with this tool.

Will this 2B class-of-fit tap produce threads that match older 2B fasteners I already use?

Yes, the 2B class of fit and 2B thread limit ensure compatibility with existing 2B hardware and standard unified fine threads.
