Threading Tool For Internal Threads
The Cleveland C55220 is a straight flute hand tap designed to cut internal threads in a variety of materials. It features a 5/16"-18 UNC thread size with a bottoming chamfer for threading close to the bottom of blind holes. The tool is constructed from High Speed Steel with a Titanium Nitride coating for improved wear resistance.
Verify Hole Size And Thread Compatibility
Before ordering, confirm that your drilled hole matches the 75 percent thread drill size F specification for this tap. Ensure the workpiece material is suitable for High Speed Steel tooling and that the required class of fit is 2B. The right-hand thread direction must match your application requirements.
Suited For Maintenance And Short-Run Threading
This tap suits mechanics and machinists creating or repairing 5/16"-18 UNC threads in through or blind holes. The bottoming design allows threading near the hole bottom. It is not suited for high-volume production runs requiring spiral point or spiral flute geometries for chip evacuation. Buyers needing different thread standards, sizes, or limits should look at other options.
