Cleveland C96125 Spiral Point Tap

This Cleveland C96125 is a spiral point tap designed for creating UNF threads in a 9/16 in -18 size. It is built from cobalt with a black oxide finish for durability in professional threading tasks. The tool features a right-hand thread direction and three flutes for efficient chip evacuation.

Installation uses a standard tap handle

The plug chamfer style helps start threads smoothly in through-holes. Correct drill size is critical; the 75 percent thread specification requires a 12.90 mm drill. Using an incorrect drill diameter or insufficient lubrication often leads to tap breakage or oversized threads.

Suits machinists cutting 9/16 UNF threads

This tap fits applications needing a Class 2B fit with a 2B thread limit. It is not for left-hand threading, metric thread forms, or pipe thread standards. Buyers needing a bottoming chamfer for blind holes or a different thread limit class should look at other options.

The box contains the single C96125 spiral point tap; you must supply the 12.90 mm drill bit, cutting fluid and a suitable tap wrench or holder.

Which version of this tap should I choose for a standard UNF hole?

Select the C96125 model with 9/16-18 UNF thread size, 2B class of fit and three-flute cobalt construction for general-purpose right-hand threading.
