Cleveland C54737 Straight Flute Tap

This Cleveland C54737 straight flute hand tap cuts UNF threads at 1/2"-20 pitch. It is made from high speed steel with a bright uncoated finish. The taper chamfer helps start threads smoothly in through holes. Right hand thread direction suits standard fastening applications.

Suited for manual threading in general purpose

Machinists and maintenance technicians creating new internal threads or chasing damaged ones will find this tool appropriate. The H3 thread limit produces a 2B class of fit for standard assemblies. Buyers needing bottoming taps for blind holes or coated tools for high volume production should look at something else.

Simple hand operation with standard tap wrench

The 3.38 in overall length and 1.66 in thread length fit common wrenches. Use the specified 11.40 mm drill size for 75 percent thread engagement. Applying cutting fluid prevents chip welding in steel. Misaligned starts or insufficient lubrication are the usual causes of tap breakage.

Questions about this item

What size tap drill do I need to use with the 1/2"-20 thread?

Use a 11.40 mm drill to achieve 75 percent thread depth before tapping.

Will the 3.38 in overall length fit inside my pneumatic tapping arm?

The tap measures 3.38 in overall with a 1.66 in thread length; verify your arm's maximum tool envelope.

How do I confirm the threads I cut meet the H3 limit and 2B fit?

Gauge the finished hole with a 1/2"-20 UNF 2B go/no-go thread gauge; the go member must pass and the no-go must stop.
