Product Identity

The Cleveland C55228 is a straight-flute hand tap for cutting 7/16"-14 UNC threads. It suits machinists and maintenance crews who need to create internal threads in through-holes or blind holes using hand or pneumatic tools.

Thermals, Noise, Power

As a non-powered cutting tool, it generates no operational noise and draws no electricity. Heat produced during tapping depends on the workpiece material, cutting speed and lubrication used by the operator.

Sustained Load Behaviour

The high-speed steel body with TiN coating resists wear during repeated threading cycles. Its bottoming design and four-flute geometry maintain thread accuracy in extended production runs without the risk of motor overheating or duty-cycle limits.

Questions about this item

How do I start a 7/16"-14 UNC thread with this H3 bottoming tap without breaking it?

Drill the hole to size U for 75 percent thread depth, then enter the tap straight with steady pressure; the bottoming chamfer cuts full threads to the hole floor, so do not force the last turns.

When will the TiN-coated high-speed steel flutes need replacement?

Replace the tap when the cutting edges no longer produce clean threads or when the TiN coating has worn through to the base steel, which typically occurs after many hundreds of holes in mild steel.

What limits how many 7/16"-14 holes I can tap continuously before the tool overheats?

The straight-flute design traps chips in deep holes, so chip packing and heat buildup in the high-speed steel body become the limiting factor during sustained use.
