Creates #8-32 UNC threads in through-holes using a 3-flute cobalt spiral-point tap with black oxide coating
- #8-32 UNC thread cuts cleanly in tough materials
- Cobalt steel with black oxide resists wear and heat
- Spiral-point design pushes chips ahead for smoother tapping
- 3-flute geometry balances strength and chip clearance
- 2B class of fit ensures accurate, repeatable threads
Cleveland C86208 Spiral Point Tap #8-32 UNC
This Cleveland C86208 spiral point tap cuts internal threads in #8-32 UNC sizes. The cobalt construction with black oxide finish provides wear resistance for general-purpose threading tasks. It features three flutes and a plug chamfer for through-hole applications. Right-hand thread direction matches standard fastener requirements.
Suitable for machine tapping through-holes.
The plug chamfer and spiral point design push chips ahead of the tap, making it suited for through-hole production in materials where cobalt performs well. It is not designed for blind holes where chip evacuation requires a bottoming or spiral-flute tap. Users needing a different thread limit or class of fit should select another tool.
Thread size #8-32 UNC with 3 flutes and 2B limit
The tap cuts a #8-32 UNC thread to a 2B class of fit with a thread limit of 2B. Three flutes provide balanced chip clearance and tool strength. The 75 percent thread drill size is 3.40 mm. Overall length is 2 31/64 in with a thread length of 53/64 in.

Questions about this item
How deep can the spiral-point tap cut threads in a single pass before chip clearance becomes an issue?
The tap has a thread length of 53/64 in, which is the maximum depth it can cut in one pass before chips may need clearing.
Does the cobalt black-oxide finish help reduce heat buildup during extended tapping sessions?
The cobalt material with black-oxide coating provides wear resistance and helps dissipate heat during prolonged use.
What drill bit size must I already own to prepare the correct 75 percent thread hole for this tap?
A 3.40 mm drill bit is required to produce the proper 75 percent thread engagement for the #8-32 UNC tap.
