Cleveland C55300 Spiral Point Tap 6-32 Unc Hss Tin

Product Description

The CLEVELAND C55300 is a spiral point tap designed for through-hole threading in metalworking and fabrication applications. It cuts a 6-32 UNC thread profile using a 2-flute, plug chamfer geometry that drives chips forward and out of the hole, reducing clogging in through-hole operations. The tap is manufactured from high speed steel (HSS) with a titanium nitride (TiN) coating that increases surface hardness and extends tool life compared to uncoated HSS. It carries an H3 thread limit and a Class 2B fit tolerance, which meets standard fastener thread requirements across most commercial and industrial assemblies. Overall length is 2.0 inches with a thread length of 0.38 inches.

The C55300 is suited for through-hole tapping in alloy steel, carbon steel, and aluminum workpieces. It is commonly used in machine shops, maintenance and repair operations, and light manufacturing environments where 6-32 UNC threaded holes are required in moderate-volume production. The right-hand thread direction and plug chamfer make it a practical choice for both manual tap handle use and machine tapping setups. The TiN finish provides added durability when running higher cycle counts on production runs.

Key Features

• 6-32 UNC thread profile with H3 thread limit for Class 2B fit tolerance
• 2-flute spiral point geometry pushes chips forward, optimized for through-hole applications
• High speed steel construction with TiN coating for increased wear resistance
• Plug chamfer for progressive thread engagement and reduced entry force
• Right-hand cut, no coolant-through requirement
• Overall length of 2.0 inches, thread length of 0.38 inches, shank diameter of 0.141 inches

Compatibility

Designed for through-hole tapping in alloy steel, aluminum, and carbon steel workpieces requiring a 6-32 UNC, Class 2B thread. Part of the CLEVELAND Series 1011TN.

Installation Notes

This tap is intended for use by machinists and maintenance technicians in both manual and machine tapping applications. Ensure the workpiece is securely fixtured and the tap is aligned perpendicular to the hole before engagement. Use an appropriate cutting fluid for the material being tapped to extend tool life and improve thread quality. Do not force the tap if resistance increases unexpectedly, as breakage in small-diameter taps can occur without warning.
