Cleveland C54731 Hand Tap Kit
The Cleveland C54731 is a three-piece straight flute hand tap set designed for cutting 1/2"-13 UNC threads in a range of materials. It suits maintenance technicians, machinists and workshop users who need to create or repair internal threads by hand.
High-speed steel construction with four flutes
Each tap is made from uncoated high-speed steel with four flutes to evacuate chips during manual threading. The set requires a 27/64 inch tap drill to produce the 75 percent thread depth before the tap cuts the 15/16 inch thread length within the 3 3/8 inch overall length.
Replaces worn or missing UNC taps
This kit replaces individual worn taps or incomplete sets when cutting right-hand Class 3B threads to a 2B limit. The jump is worth it when a single damaged tap halts a repair job or when a new project demands accurate UNC threads without machine tooling.

Questions about this item
What thread limit and class of fit does the 1/2"-13 UNC tap provide?
The tap is manufactured to a 2B thread limit and produces a 3B class of fit for right-hand threads.
How much heat builds up when tapping steel with this high-speed steel tool all day?
High-speed steel retains hardness at elevated temperatures, so the tap resists softening during extended use in steel.
What drill size must I already have to prepare the 75 percent thread hole?
A 27/64 in drill bit is required to produce the correct tap-drill hole for 75 percent thread engagement.
