Cleveland C54782 Straight Flute Hand Tap
The Cleveland C54782 is a straight flute hand tap designed for creating 5/8"-11 UNC threads. It suits machinists and maintenance technicians who need to produce Class 3B internal threads in through-holes or blind holes.
Sustained cutting performance
High-speed steel construction maintains hardness during extended threading operations. The bright uncoated finish allows lubricant adhesion while the four-flute design evacuates chips efficiently through continuous use. Thread limit H3 controls size consistency across repeated cuts.
Thread specification
This tap cuts right-hand UNC threads to a 5/8"-11 size with a 1 13/16 inch thread length and 3 13/16 inch overall length. It requires a 13.60 mm drill for 75 percent thread engagement. Buyers needing a different thread pitch or diameter cannot use this tool.

Questions about this item
How much heat does the 4-flute HSS tap generate during extended threading?
The uncoated high-speed steel tap produces typical cutting heat for UNC 5/8"-11 threads; use cutting fluid to manage temperature during long runs.
What drill size must I already have to prepare the hole for this 5/8"-11 UNC tap?
A 13.60 mm drill bit matching the 75 percent thread drill size is required before tapping.
Will the H3 thread limit and 3B class of fit work with older UNC bolts I already own?
Yes, the H3 limit and 3B fit are standard for UNC 5/8"-11, so existing bolts of the same specification will engage correctly.
