Cleveland C54728 Hand Tap
The Cleveland C54728 is a straight flute hand tap designed for creating internal threads in a variety of materials. It is intended for mechanics and machinists who need to cut precise UNC threads by hand or with a tapping head.
1/2"-13 UNC Thread Specification
This tap cuts a 1/2"-13 UNC thread with a Class 2B fit and H3 thread limit. It requires a 27/64 inch drill size for 75 percent thread engagement and features a 1.66 inch thread length within a 3.38 inch overall length.
High-Speed Steel Bright Finish Suitability
The bright, uncoated high-speed steel construction suits general-purpose threading in steel and non-ferrous metals where coatings are not required. Buyers needing coated taps for high-volume production or difficult alloys should look at something else.

Questions about this item
What does the 1/2"-13 UNC size mean when I am cutting threads in a workshop?
It cuts a half-inch diameter thread with 13 threads per inch in Unified National Coarse form, producing a standard right-hand thread for general-purpose fastening.
How does the H3 thread limit and 2B class of fit affect the finished hole?
H3 allows a slightly oversized pitch diameter while 2B provides a standard medium fit, so the tap produces threads that accept common bolts without excessive play.
What drill size and clearance do I need before tapping with this tool?
Use a 27/64 inch drill for 75 percent thread engagement; the tap overall length is 3.38 inches with a 1.66 inch thread length, so ensure the workpiece and holder accommodate that reach.
