Cleveland #8-32 UNC spiral point tap
This Cleveland C96108 is a cobalt spiral point tap with three flutes for #8-32 UNC threads. It measures 2 31/64 inches overall with a 53/64 inch thread length and a 2B class of fit. The black oxide finish adds wear resistance for general machine tapping.
Suited for through-hole threading in steel
The spiral point design pushes chips ahead of the tap, making it effective for through-hole work in ferrous materials. It is not intended for blind holes where chips must be lifted out, nor for hand tapping without a machine spindle. Buyers needing a bottoming or plug chamfer for blind holes should select a different tap geometry.
75 percent thread drill size 3.40 mm
The 75 percent thread engagement requires a 3.40 mm drill size to produce the correct 2B class of fit. Using a different drill diameter will change the thread percentage and may cause oversize or undersize threads. Verify the drill size before starting the job.

Questions about this item
How do I install the #8-32 UNC spiral point tap and what step is often missed?
Use a 3.40 mm drill for the 75 percent thread hole, then run the tap straight with cutting fluid; the step many skip is clearing chips every half-turn to avoid binding in the 53/64 in thread length.
What maintenance or replacement will the Cleveland C96108 tap need later?
The cobalt body with black oxide coating resists wear, but the three flutes will dull after repeated use; replace the tap when threads show tear-out or the 2B class of fit can no longer be held.
What limit appears first when tapping deeper holes under sustained use?
Chip evacuation in the 53/64 in thread length becomes the limiting factor; packed flutes increase torque and can break the tap before the 2 31/64 in overall length is reached.
