Cleveland Straight Flute Hand Tap

The Cleveland 54452 is a straight flute hand tap designed for cutting internal threads. It suits machinists and maintenance technicians who need to create or repair UNC threads in a variety of materials.

Thread size and drill requirement

Verify that the workpiece material suits high speed steel cutting tools. Ensure the correct 75 percent thread drill size number 7 is available for the 1/4"-20 UNC specification before starting the job.

Suited for through-hole and blind-hole work

This tap suits users cutting right-hand threads with a 3B class of fit. It is not for buyers who need coated tools for high-volume production or those requiring spiral point or spiral flute geometry for chip evacuation.

Questions about this item

Does the three-piece tap kit include the #7 drill bit needed for 75 percent thread engagement, or must it be purchased separately?

The kit contains three straight-flute hand taps sized 1/4"-20 UNC; the #7 drill bit for 75 percent thread depth is not included and must be bought separately.

Which thread-limit class should I select — the H2 limit with 3B fit or another option — for a standard 1/4"-20 UNC hole?

The supplied tap carries an H2 thread limit and Class 3B fit, which is the standard choice for general-purpose 1/4"-20 UNC threading in steel.

What does the 1 inch thread length and 2 1/2 inch overall length mean when I am tapping a through-hole in a typical workpiece?

The 1 inch thread length provides full thread engagement for holes up to that depth, while the 2 1/2 inch overall length gives enough shank clearance for hand tapping through standard material thicknesses.
