Cleveland C55130 Hand Tap 7/16-20 Unf Plug Tin Hss

Product Description

The CLEVELAND C55130 is a 7/16-20 UNF plug-chamfer hand tap designed for threading operations in both blind holes and through-holes. Built from high speed steel with a titanium nitride (TiN) coating, it delivers extended cutting life and reduced friction compared to uncoated tooling. The 4-flute straight-flute geometry provides balanced cutting action and is well-suited to a wide range of ferrous and non-ferrous materials. With an H3 thread limit and Class 2B fit, this tap produces threads to standard tolerance for general-purpose fastener applications. Machinists, tool-and-die makers, and maintenance technicians use this tap in manual tapping operations with a standard tap wrench or tapping stand.

This tap is suited for threading 7/16-20 UNF threads in workshop, production, and field maintenance environments. Its right-hand cutting direction and plug chamfer make it appropriate for starting threads in both blind and through-hole applications. Compatible material applications include alloy steel, aluminum, carbon steel, and free-machining stainless steel. The Series 1002TN designation identifies it within the Cleveland TiN-coated hand tap line.

Key Features

• TiN coating for improved wear resistance and lubricity over uncoated HSS
• 4-flute straight-flute design provides stable, balanced cutting action
• Plug chamfer for versatile use in blind holes and through-holes
• H3 thread limit, Class 2B fit for standard general-purpose UNF thread tolerance
• Right-hand cutting direction, compatible with standard tap wrenches and tapping stands
• Rated for alloy steel, aluminum, carbon steel, and free-machining stainless steel

Compatibility

Designed for 7/16-20 UNF tapping applications in alloy steel, aluminum, carbon steel, and free-machining stainless steel workpieces where a plug-chamfer, straight-flute hand tap is required.

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 fixtured and the tap is started square to the hole before applying cutting pressure. Apply appropriate cutting fluid for the material being tapped to extend tool life. Do not force or back-drive the tap against resistance; back off periodically to break chips and prevent tap breakage.
