Cleveland C96016 Spiral Point Tap for UNC Threads

This Cleveland C96016 spiral point tap cuts 5/16-18 UNC threads in through-holes. The cobalt construction with Hard Lube coating suits machine tapping in tougher alloys. It is intended for machinists and maintenance technicians who need reliable thread production in steel or stainless steel.

Plug Chamfer Starts Easily in Through Holes

The plug chamfer on this 3-flute tap provides a moderate lead for easier alignment when starting threads. Spiral point geometry pushes chips ahead of the cut, reducing flute clogging in through-hole applications. Breakage usually occurs if the drill size is incorrect or if cutting fluid is omitted during deep cuts.

Verify Drill Size F and 2B Class of Fit Before

Confirm your workpiece uses a 75 percent thread drill size F to match the 5/16-18 UNC specification. The tap conforms to a 2B class of fit with a thread limit of 2B. Ensure your machine spindle runs right-hand rotation and can accommodate the 3 35/64 inch overall length and 1 3/8 inch thread length.

Questions about this item

How can I confirm the C96016 tap is cutting correctly after setup?

Check that the spiral point pushes chips ahead cleanly, threads measure to the 2B class of fit, and the 1 3/8 in thread length matches the spec.

What comes in the box with the C96016 and what must I supply?

The box contains the cobalt spiral point tap only; you must provide a 5/16-18 UNC drill size F hole and a tap wrench or holder.

Which version of the C96016 should I choose for my job?

This model is a single 5/16-18 UNC plug tap with 3 flutes, cobalt construction and Hard Lube coating — no alternate capacities are offered.
