Cleveland C55110 Hand Tap 10-32 Unf Plug Tin Hss

Product Description

The CLEVELAND C55110 is a 10-32 UNF straight-flute hand tap designed for threading operations in metalworking and machining applications. Built from high speed steel (HSS) with a titanium nitride (TiN) coating, this tap delivers extended tool life and reduced friction during cutting. It features a plug chamfer, right-hand thread direction, 4-flute geometry, and a Class 2B fit with an H3 thread limit. Overall length is 2.375 inches with a 0.875-inch thread length and a 0.194-inch shank diameter. It is suited for use by machinists, tool-and-die technicians, and maintenance professionals who require precise internal threading.

The C55110 is applicable for both blind-hole and through-hole threading operations. The 10-32 UNF thread form makes it a common choice in precision assemblies, instrumentation, and light mechanical work where fine-thread engagement is required. Compatible material applications include alloy steel, aluminum, carbon steel, and free-machining stainless steel. The straight-flute design is well-suited to through-hole applications and works efficiently in horizontal or vertical machine setups as well as hand-tapping operations.

Key Features

• 10-32 UNF right-hand thread, Class 2B fit with H3 thread limit
• High speed steel construction with TiN coating for improved wear resistance and tool longevity
• Plug chamfer allows for progressive thread engagement, suitable for through-holes and partially blind holes
• 4-flute straight-flute geometry for clean chip formation in a range of metals
• No coolant-through requirement, compatible with standard cutting fluids applied externally
• Rated for alloy steel, aluminum, carbon steel, and free-machining stainless steel

Compatibility

Designed for blind-hole and through-hole threading in alloy steel, aluminum, carbon steel, and free-machining stainless steel workpieces. Part of the Cleveland Series 1002TN tap line.

Installation Notes

This tap is intended for use by qualified machinists or maintenance technicians familiar with hand and machine tapping procedures. Before tapping, ensure the workpiece is securely fixtured and the correct drill size for a 10-32 UNF thread has been used. Apply a suitable cutting fluid for the workpiece material to reduce heat and extend tap life. Avoid forcing the tap into the hole; back off periodically to break chips, particularly in blind-hole applications.
