Cleveland C96020 Spiral Point Tap
The Cleveland C96020 is a cobalt spiral point tap designed for creating 7/16-14 UNC threads in tough materials. Its 3 15/16 inch overall length and 1 39/64 inch thread length suit standard through-hole applications. The three-flute design with Hard Lube coating improves chip evacuation and extends tool life. It meets Class of Fit 2B specifications for general-purpose threading work.
Upgrade from standard high-speed steel taps
Cobalt construction handles higher cutting temperatures when tapping stainless steel or high-strength alloys where standard tools wear quickly. The spiral point geometry pushes chips ahead of the cut, reducing torque and the risk of tap breakage in deep through-holes. The jump is worth it when production volume or material hardness causes frequent tap failure or poor thread finish with conventional taps.
Limits of UNC thread form and plug chamfer
The Unified Coarse thread form sacrifices fine adjustment for faster assembly and better resistance to stripping in softer materials. A plug chamfer requires adequate hole depth beyond the full thread length to start cleanly. The 75 percent thread drill size U constraint limits engagement strength compared to deeper thread percentages. Right-hand cutting direction restricts use to conventional thread orientation only.

Questions about this item
What drill bit size is required for the 7/16-14 UNC thread?
Use a U-size drill bit to achieve the 75 percent thread depth before tapping.
How do I start the tap straight in the hole?
Apply cutting fluid, align the tap perpendicular to the workpiece, and turn the tap wrench with steady pressure for the first few threads.
When should this cobalt tap be replaced?
Replace the tap when cutting edges become dull, chips clog the flutes, or thread gauge checks show the 2B class of fit is no longer met.
