Cleveland C55396 Spiral Point Tap 5/8-11 UNC 3 Flutes

SKU CH-47AN-HE37X

Spiral point tap cuts 5/8-11 UNC threads in through-holes using three flutes and TiCN-coated high-speed steel

  • Spiral point design pushes chips forward for smoother tapping
  • High-speed steel with TiCN coating resists wear in tough materials
  • 5/8-11 UNC thread size fits standard coarse-thread applications
  • Three flutes balance strength and chip clearance in through-holes
  • 75 % thread drill size 13.60 mm ensures accurate hole preparation

Cleveland Spiral Point Tap 5/8-11 UNC

The Cleveland C55396 Spiral Point Tap cuts 5/8-11 UNC threads in a single pass. Its spiral point design pushes chips ahead of the flutes, making it suited for through-hole work in steel and alloy. High-speed steel construction with TiCN coating resists wear during repeated use. Three flutes provide stable cutting action and efficient chip evacuation.

Suited for through-hole threading

This tap handles right-hand UNC threads where a 75 percent thread depth is specified with a 13.60 mm drill size. The H3 limit and 2B class of fit match standard production tolerances. It is not intended for blind holes where chips must be lifted out, nor for left-hand thread forms. Users needing a bottoming or taper chamfer should select a different tap style.

Thread size 5/8-11 UNC with H3 limit and 2B fit

The 5/8 inch diameter and 11 threads per inch define the thread form, while the H3 pitch diameter limit and 2B class of fit control the allowance and tolerance. These values determine whether the finished thread meets the required specification for the mating part. Verify the thread designation and fit class against the engineering drawing before tapping.

Questions about this item

When will the TiCN coating on this C55396 tap need replacement?

The TiCN coating wears gradually; replace the tap when thread quality drops or the 3 flutes show visible rounding, as re-coating is not standard practice.

What limit appears first during sustained threading with the 5/8-11 UNC size?

Chip evacuation through the 3 spiral-point flutes becomes the limiting factor before the H3 thread limit is reached in deep holes.

How much heat builds up when running this high-speed steel tap all day?

High-speed steel with TiCN coating manages heat well; use cutting fluid to keep temperatures controlled during continuous 5/8-11 UNC threading.
