Cleveland C54784 Straight Flute Hand Tap
The Cleveland C54784 is a straight flute hand tap designed for cutting internal threads in a variety of materials. It suits maintenance technicians and machinists who need to create or repair 5/8"-11 UNC threads using hand-operated or powered tapping equipment.
Replacing worn or damaged taps
Switch to this tap when an existing 5/8"-11 UNC tool shows flank wear, chipped teeth or produces oversized threads that exceed the 2B-3B class of fit. The H5 thread limit and high-speed steel construction restore consistent pitch diameter control for through-hole or blind-hole applications.
Verify drill size and hole depth
Confirm the tapped hole is drilled to the 13.60 mm diameter specified for 75 percent thread engagement. Ensure the workpiece allows at least 1.81 in of thread length within the 3.81 in overall tool length and that the machine or hand holder accommodates a right-hand, uncoated HSS tap.

Questions about this item
What drill bit size matches the 5/8"-11 UNC tap for 75 percent thread?
Use a 13.60 mm drill bit to prepare the hole before tapping with this 5/8"-11 UNC tool.
How do you start the Cleveland C54784 straight-flute tap straight in the hole?
Apply steady axial pressure while turning the tap clockwise; the straight flutes need manual alignment so keep the tap perpendicular to the workpiece.
When does the H5 class-of-fit tap need replacement?
Replace the tap when threads cut to the 2B-3B limit become oversize or the high-speed steel cutting edges dull after repeated use.
