Cleveland C54893 Straight Flute Hand Tap
The Cleveland C54893 is a straight flute hand tap designed for creating internal threads in metal workpieces. It suits machinists and maintenance technicians who need to cut precise UNF threads by hand or with a tapping head.
7/8"-14 UNF thread capacity and H4 limits
This tap cuts a 7/8"-14 UNF thread with a Class 3B fit and H4 thread limit. The four-flute high-speed steel body handles general-purpose materials, while the 75 percent thread drill size of 20.40 mm provides appropriate engagement for standard through-holes.
Three-piece kit for progressive threading
The set includes taper, plug, and bottoming taps to start, continue, and finish threads in a single operation. Bright uncoated finish requires cutting fluid for chip evacuation and tool life. Right-hand thread direction matches standard fastener conventions.

Questions about this item
Will the 7/8"-14 UNF thread work with my existing 7/8"-14 UNF dies and gauges?
Yes, the tap cuts a standard UNF 3B class of fit with right-hand thread direction, matching 7/8"-14 UNF dies and gauges.
How can I verify the 7/8"-14 threads are cut to the correct 3B fit after tapping?
Check the finished threads with a 7/8"-14 UNF 3B thread plug gauge; the GO member should enter and the NO-GO should not.
Does the three-piece kit include the 20.40 mm drill bit for the 75 percent thread depth?
No, the kit contains only the taper, plug and bottoming taps; the 20.40 mm drill bit must be purchased separately.
