Cleveland C55204 Hand Tap 8-32 Unc Bottoming Tin Hss

Product Description

The CLEVELAND C55204 is a 4-flute straight flute hand tap designed for cutting 8-32 UNC internal threads in a range of ferrous and non-ferrous materials. Built from high speed steel with a titanium nitride (TiN) coating, it offers improved wear resistance and longer tool life compared to uncoated HSS taps. The bottoming chamfer style allows threads to be cut close to the bottom of a blind hole. Overall length is 2.125 inches with a thread length of 0.38 inches and a shank diameter of 0.168 inches. This tap is suited for machine shops, maintenance technicians, and field service professionals working with precision fastener threads.

The C55204 is rated for both blind hole and through-hole threading applications. It carries a Class of Fit 2B and Thread Limit H3, making it appropriate for standard tolerance threaded assemblies. Compatible material applications include alloy steel, aluminum, carbon steel, and free-machining stainless steel. The right-hand thread direction and straight flute geometry make this tap suitable for use in hand tapping operations or with a tapping fixture at low spindle speeds. Coolant-through is not supported on this tool.

Key Features

• Bottoming chamfer for threading close to the bottom of blind holes
• TiN coating extends tool life and reduces friction during cutting
• High speed steel construction handles a broad range of workpiece materials
• 4-flute straight flute design provides good chip control in through-hole and shallow blind-hole work
• Class of Fit 2B and Thread Limit H3 for standard precision assemblies
• No coolant-through requirement simplifies setup in hand or manual tapping operations

Compatibility

Designed for blind hole and through-hole threading in alloy steel, aluminum, carbon steel, and free-machining stainless steel. Part of the Cleveland Series 1003TN tap line.

Installation Notes

This tap is installed by machinists or maintenance technicians using a standard tap wrench or tapping fixture. Always ensure the workpiece is securely clamped and the tap is started square to the hole to avoid thread damage or tool breakage. Apply appropriate cutting fluid for the workpiece material before tapping. Disconnect power to any machine spindle before hand-tapping in place.
