Cleveland C96009 Spiral Point Tap #8-36 UNF Cobalt
The Cleveland C96009 is a spiral point tap designed for creating #8-36 UNF threads in through-hole applications. It is built from cobalt steel with a Hard Lube coating for extended tool life. The tap features three flutes and a right-hand thread direction suited for standard machining operations. This tool targets machinists and maintenance technicians requiring precise Class 2B fit threads.
Sustained cutting performance
The cobalt substrate maintains hardness at elevated temperatures generated during continuous threading cycles. Spiral point geometry pushes chips ahead of the tap, reducing flute clogging and torque buildup during long production runs. Hard Lube coating lowers friction at the cutting interface, allowing consistent feed rates without overheating. The three-flute design balances chip clearance with core strength for reliable performance in steel and alloy workpieces.
UNF threading limits and drill size constraints
The tap produces a Class 2B fit with a 75 percent thread engagement when used with a #29 drill size. Thread length is fixed at 53/64 in within an overall length of 2 31/64 in, limiting maximum hole depth. The #8-36 UNF specification defines the pitch diameter tolerance window that cannot be exceeded. Users must verify workpiece material and hole preparation match these geometric constraints before tapping.

Questions about this item
Does the cobalt construction and Hard Lube coating keep the C96009 tap running cooler during extended threading jobs?
The cobalt material and Hard Lube coating reduce friction and heat buildup, helping the tap maintain performance during prolonged use.
What drill bit size must I already have to prepare the correct 75 percent thread hole for this #8-36 UNF tap?
You need a #29 drill bit to produce the recommended 75 percent thread depth before tapping.
Will the 2B class of fit on this tap mate cleanly with existing UNF hardware I already use?
Yes, the 2B thread limit matches standard UNF Class 2B specifications, so it will engage properly with compatible nuts and bolts.
