Cleveland C54724 Hand Tap — Purpose and User

This Cleveland C54724 straight flute hand tap cuts 1/2"-13 UNC threads in through holes or deep blind holes. The plug chamfer and four-flute design suit general-purpose threading in steel, cast iron and non-ferrous metals. It is built for maintenance technicians, machinists and DIY builders who cut new internal threads or repair damaged ones using a tap wrench.

Check Before Ordering

Verify that your drilled hole matches the 75 percent thread drill size of 27/64 in before starting the cut. Confirm the workpiece material is compatible with uncoated high-speed steel and that you can hold the tap square to the hole. The thread limit H1 and class of fit 2B determine the final tolerance, so ensure this matches the specification for the mating fastener.

Bright Finish and Geometry Effects

The bright, uncoated surface requires cutting fluid to reduce friction and prevent built-up edge during hand tapping. Four flutes provide stronger cutting edges and better chip evacuation in ductile materials than two- or three-flute taps. The 15/16 in thread length and 3 3/8 in overall length give sufficient reach for standard hole depths without bottoming out.

Questions about this item

Does the Cleveland C54724 tap come with a handle or drill bit, or must I buy them separately?

The tap is sold as a single cutting tool. A tap wrench for hand threading and a 27/64 inch drill bit for the 75 percent thread hole are not included.

How do I know the C54724 is the right version for my 1/2 inch UNC job?

It cuts 1/2"-13 UNC threads to a 2B class of fit with an H1 thread limit, using a plug chamfer and four straight flutes in high-speed steel.

What does the 3 3/8 inch overall length mean when I am tapping a blind hole?

The 15/16 inch thread length is the cutting portion; the extra shank length clears the hole depth so the tap can start and run true without bottoming out.
