Threaded hole tooling for #6-32 UNC
The Cleveland C86206 spiral point tap cuts #6-32 UNC threads in a right-hand direction. It is made from cobalt with a black oxide surface treatment. The plug chamfer and three-flute design suit through-hole applications. Machinists and maintenance technicians use it to produce 2B class-of-fit threads.
Chip evacuation under sustained load
The spiral point geometry pushes chips ahead of the tap so they do not pack the flutes during continuous cutting. This behaviour keeps the cutting edges clear when threading multiple holes in sequence. The 25/32 in thread length engages the full depth of the hole. A #36 drill at 75 percent thread provides the correct tap drill size.
Heat and wear resistance in normal use
Cobalt construction resists the heat generated by repeated threading cycles. The black oxide finish reduces galling and helps retain cutting fluid on the tool surface. These characteristics lower cutting torque and extend tool life in steel and similar materials. The 2 13/64 in overall length fits standard tap holders.

Questions about this item
How much heat does the #6-32 spiral point tap generate when running all day in a power tool?
The cobalt black oxide tap cuts with a 75 percent thread drill size #36 and 25/32 in thread length, so heat stays low in normal use.
What drill bit must I already own to prepare the hole for this #6-32 UNC tap?
You need a #36 drill bit to create the 75 percent thread hole before tapping.
Will the 2 13/64 in overall length and 2B class of fit work with my older #6-32 hardware?
Yes, the 2B class of fit and standard UNC threads match existing #6-32 bolts and nuts.
