Cleveland 55122 UNF Threading Tool
This Cleveland 55122 straight flute tap cuts 5/16-24 UNF threads in a single pass. The plug chamfer and four flutes suit general-purpose threading in steel and non-ferrous metals. Right-hand orientation and H3 thread limit produce a Class 2B fit. High-speed steel with TiN coating extends edge life for workshop and maintenance tasks.
Installation Notes
Secure the workpiece and select the 75 percent thread drill size I before starting. Apply cutting fluid and advance the tap with steady, aligned pressure to avoid cross-threading. The 11/16 in thread length and 2 23/32 in overall length require adequate clearance in the setup. Reverse periodically to break chips and prevent flute packing.
Sustained Use Behaviour
TiN coating reduces friction during repeated cuts, maintaining dimensional accuracy over longer runs. High-speed steel resists softening when heat builds in continuous threading operations. Four-flute design evacuates chips efficiently, lowering torque spikes that can damage threads. The tool remains consistent for batch work without frequent resharpening.

Questions about this item
How do I verify the 5/16-24 UNF tap is cutting threads correctly after setup?
Check that the drilled hole uses the 75 percent thread drill size I and that the resulting threads match the class of fit 2B specification with a thread limit of H3.
What comes in the box and what must be purchased separately for the Cleveland 55122 tap?
The box contains the straight flute tap with TiN coating, four flutes, plug style and right-hand thread direction; a drill bit matching the 75 percent thread drill size I and cutting fluid are not included.
Which thread size and style should I choose among the listed versions for this tap?
The product is a single 5/16-24 UNF plug tap with 11/16 in thread length, 2 23/32 in overall length, H3 limit and 2B class of fit; no other versions or capacities are offered.
