- Right-hand cutting for standard threading applications
- Overall length 2 13/64 in with 25/32 in thread length
Thread Cutting Tool for #6-40 UNF Holes
The Cleveland C86107 spiral point tap creates internal threads in #6-40 UNF sizes using a 3-flute cobalt body with TiAlN coating. It suits machinists and maintenance teams cutting right-hand threads to a 2B class of fit in through-hole applications.
Plug-Style Geometry for Through-Hole Work
The plug chamfer pushes chips ahead of the cut so they exit the hole rather than packing the flutes. A 75 percent thread drill size #33 prepares the workpiece, and the 25/32 in thread length sets the depth of engagement without requiring a bottoming tap.
Cobalt Substrate with TiAlN Coating
Cobalt material resists heat buildup during extended cutting cycles while the TiAlN surface lowers friction and wear. The 2 13/64 in overall length fits standard tap holders and CNC tool changers for consistent performance in steel and stainless alloys.

Questions about this item
What thread limit does the Cleveland C86107 tap produce for #6-40 UNF threads?
This tap cuts to a 2B thread limit and class of fit for #6-40 UNF threads.
How much heat and wear resistance does the cobalt TiAlN coating add during extended tapping?
The cobalt substrate with TiAlN coating resists heat buildup and reduces wear during sustained use in steel and alloys.
Which drill size must I already have to prepare the correct 75 percent thread hole?
A #33 drill is required to produce the proper 75 percent thread engagement before tapping.
