Cleveland C54280 Tap Kit — Purpose
The Cleveland C54280 is a three-piece straight-flute hand tap kit for cutting #8-32 UNC threads. It suits mechanics and hobbyists who need to create new internal threads or repair damaged ones in metal workpieces. The H3 limit and 2B class of fit target general-purpose fastening jobs.
Installation Notes
Straight-flute taps cut on the forward stroke and require frequent reversal to break chips, especially in deep holes. Use the 3.40 mm drill for the 75 percent thread depth before tapping. Apply cutting fluid and keep the tap aligned to avoid tap breakage or oversized threads.
Pre-Order Checks
Verify the workpiece material is compatible with high-speed steel uncoated taps. Confirm the required thread standard is UNC #8-32 with right-hand direction. Ensure you have a tap wrench that fits the 2 1/8 in overall length and can accommodate the four-flute design.

Questions about this item
How can I verify the tap is cutting correctly after starting the thread?
The tap should produce clean, continuous chips and advance smoothly through the 3/4 in thread length without binding; the finished thread must accept a standard #8-32 UNC 2B gauge.
What comes in the package and what additional tools are required?
The kit includes three straight-flute hand taps; you will need a tap wrench and a 3.40 mm drill bit for the 75 percent thread hole.
Which thread limit should I select for a standard class 2B fit?
The H3 limit supplied in this kit is the correct choice for a #8-32 UNC class 2B internal thread.
