Threading Tap for 1/2 Inch UNC Holes
The Cleveland C55232 is a straight flute hand tap designed to cut internal threads in a 1/2 inch -13 UNC size. It is made from high speed steel with a titanium nitride coating for wear resistance. The bottoming chamfer allows threading close to the bottom of a blind hole. This tool suits maintenance technicians and machinists producing class 2B fit threads.
Thread Limit H3 Determines Fit
The single specification that decides whether this is the correct part is the H3 thread limit. This limit defines the pitch diameter tolerance relative to the basic size for a class 2B fit. If the application requires a different limit such as H1, H2 or H4, this tap will produce threads that are too tight or too loose. Verify the required limit before ordering.
High Speed Steel Holds Up in Repetitive Cuts
Under sustained load the high speed steel body resists softening better than carbon steel alternatives. The TiN coating reduces friction and extends edge life during repeated hand tapping operations. The straight flute design requires the user to break chips manually, which slows the process in deep holes compared to spiral point or spiral flute geometries.

Questions about this item
What does the 1/2"-13 UNC size mean for the threads I will cut?
It cuts a half-inch diameter thread with 13 threads per inch in the Unified National Coarse series, matching standard 1/2"-13 nuts and bolts.
How does the H3 thread limit and 2B class of fit affect the finished hole?
H3 allows a slightly oversized tap for a 2B fit, giving a standard clearance that works with most general-purpose 1/2"-13 fasteners.
What drill size and tap depth do I need for a 75 percent thread?
Use a 27/64 inch drill; the tap cuts 1.66 inches of thread within its 3.38 inch overall length.
