Cleveland #2-64 UNF Straight Flute Hand Tap

This Cleveland C54094 straight flute hand tap cuts #2-64 UNF internal threads with a plug chamfer and three flutes. It is made from high speed steel with a bright uncoated finish and right-hand cutting orientation. The tool suits maintenance technicians and machinists who need to create new threads or restore damaged ones in general-purpose materials.

Practical limits of hand tapping with this size

The 1.75 in overall length and .44 in thread length restrict reach to shallow holes and through holes that can be accessed from the entry side. A 75 percent thread drill size of 1.80 mm must be prepared before tapping and the H2 thread limit produces a class 2B fit that may not satisfy tighter tolerance requirements. Chip evacuation relies on manual reversal because the straight flute design does not pull chips out of deep or blind holes.

Highlights

  • #2-64 UNF thread cuts precise fine-pitch holes
  • Plug chamfer starts threads easily in through-holes
  • High-speed steel body resists wear on repeated use
  • 75 in overall length fits standard tap handles

Questions about this item

How do I choose the right tap for a #2-64 UNF thread?

This tap is cut to a #2-64 UNF size with a 2B class of fit and H2 thread limit, so it matches holes drilled to 1.80 mm for 75 percent thread engagement.

What does the 1.75 in overall length mean when I use the tap in a handle?

The 1.75 in overall length gives a short, rigid reach; the 0.44 in thread length cuts the full profile in thin material without bottoming out.
