Cleveland Spiral Point Tap #2-56 UNC Cobalt 3 Flute

SKU CH-W8DT-T1FHY

A #2-56 UNC spiral-point tap in cobalt steel with three flutes, black-oxide finish and 35/64 in thread length

  • Spiral point design pushes chips forward for smoother threading
  • Cobalt construction resists heat and wear during high-speed tapping
  • Three flutes balance chip clearance with cutting strength
  • #2-56 UNC thread size matches precise fastener requirements
  • 35/64 inch thread length suits shallow-hole applications

Cleveland #2-56 UNC Spiral Point Tap

This Cleveland C96101 spiral point tap cuts internal threads in a #2-56 UNC size. It is made from cobalt steel with a black oxide finish for wear resistance. The tool suits machinists and maintenance technicians who need a right-hand cutting tap for through-hole applications in steel or stainless alloys.

Three-flute plug design with 75 percent drill size

The three-flute geometry and plug chamfer push chips ahead of the cut, reducing torque and preventing flute clogging in through holes. A 75 percent thread drill size of 1.73 mm prepares the correct hole for a 2B class of fit. Cobalt substrate and black oxide coating extend tool life in abrasive or work-hardening materials.

Thread limit 2B and 35/64 inch thread length

The 2B thread limit and 35/64 inch thread length determine whether this tap matches the required engagement depth and tolerance for the fastener specification. Verify the hole depth and class of fit before selecting this tool. Builders needing a different thread limit, flute count, or bottoming chamfer should choose another tap.

Questions about this item

Will the cobalt spiral-point tap need replacement once the 35/64 inch thread length section wears?

The tap is made from cobalt with a black-oxide coating for extended wear life; when the cutting edges on the 35/64 inch thread length dull, the tool is normally replaced rather than resharpened.

What limit appears first during sustained threading in #2-56 UNC holes?

The 2B class of fit and 75 percent thread drill size of 1.73 mm define the tolerance window; exceeding that fit or using an undersized drill will cause the tap to bind or break first.

Does the tap generate noticeable heat when run continuously in a power tapper?

Cobalt construction and the spiral-point design push chips ahead of the cut, reducing friction and heat buildup during continuous operation in #2-56 UNC holes.
