Cleveland C58544 Spiral Flute Tap #10-24 UNC

The Cleveland C58544 is a spiral flute tap designed to cut internal threads in through-holes and blind holes. It features a #10-24 UNC thread size with a right-hand thread direction and a class 2B fit. The tool is made from high speed steel with a bright uncoated finish and has three flutes for efficient chip evacuation during threading operations.

Suited for manual and machine tapping of #10-24

This tap suits machinists and maintenance technicians cutting #10-24 UNC threads in steel, aluminum, or plastic where chip clearance matters. The spiral flute geometry pulls chips out of blind holes, reducing breakage risk. Buyers who need a different thread pitch, diameter, or thread form should look at other tap specifications because this tool only produces #10-24 UNC threads.

Thread size #10-24 UNC with H3 limit

The single specification that decides fit is the #10-24 UNC thread size combined with an H3 thread limit for a class 2B fit. This determines the pitch diameter tolerance and ensures the finished thread gauges correctly. The 75 percent thread drill size #25 prepares the hole for this specific tap geometry.

Questions about this item

What size drill bit do I need before tapping with the #10-24 UNC spiral flute tap?

Use a #25 drill bit to achieve the 75 percent thread depth required for the #10-24 UNC thread form.

Will the three-flute design clear chips in a blind hole when I keep my older hand tap set for through holes?

The spiral flute geometry pulls chips out of blind holes, while your straight-flute hand taps remain suitable for through-hole work.

How do I verify the tap is cutting a correct class 2B thread after setup?

Check the finished thread with a #10-24 UNC 2B go/no-go thread gauge; the go gauge should enter freely and the no-go gauge should not.
