Cleveland C55226 Hand Tap
The Cleveland C55226 is a straight flute hand tap designed for cutting 3/8"-24 UNF threads in a variety of materials. It is intended for machinists, maintenance technicians and hobbyists who need to create or repair internal threads by hand or with a tapping head. The high-speed steel body with TiN coating provides wear resistance and extended tool life during threading operations.
Build integration
The tap has an overall length of 2.94 in and a thread length of 1.25 in, fitting standard tap holders and wrenches for manual use. It requires a 75 percent thread drill size of 8.50 mm to prepare the hole before tapping. The H3 thread limit and Class 2B fit ensure the finished threads meet standard tolerances for general-purpose fastening applications. Right-hand cutting direction matches conventional threading requirements.
Suitability
This tool suits users cutting UNF fine-pitch threads in steel, aluminium or plastic where a bottoming chamfer allows threading close to the bottom of a blind hole. It is not suited for buyers needing a taper or plug chamfer for through-hole work, for those requiring larger or smaller thread diameters, or for automated high-volume production where spiral-point or roll-form taps would be more efficient.

Questions about this item
Will the H3 thread limit still cut clean threads after hours of repetitive hand tapping?
The H3 limit is ground into the high-speed steel body, so the pitch diameter stays within Class 2B tolerance even during long sessions.
Does the TiN coating keep the flutes cool enough for all-day use without cutting fluid breakdown?
TiN reduces friction and heat buildup in the 1.25 in thread length, letting the tap run longer before fluid degrades.
Which tap wrench square drive matches the shank on this 3/8"-24 UNF tap?
The shank follows standard USCTI dimensions for a 3/8" hand tap, fitting any adjustable wrench made for that size.
