Kennametal 4131803 Hand Tap 6-32 Unc Plug Rh Ticn Hss

Product Description

The KENNAMETAL 4131803 is a 6-32 UNC straight-flute hand tap designed for cutting right-hand internal threads in a range of ferrous materials. Built from high-speed steel with a titanium carbonitride (TiCN) coating, it delivers improved wear resistance and tool life compared to uncoated HSS taps. The plug chamfer provides a gradual lead-in, making it well suited for through-hole tapping applications. With an overall length of 2 inches and a thread length of 11/16 inches, this tap is part of Kennametal Series 8013 and is sized for use with standard 6-32 tooling setups. It carries a 2B class of fit and an H3 thread limit for consistent, close-tolerance results.

This tap is intended for hand tapping operations in cast iron, stainless steel, and carbon steel workpieces. The 3-flute straight-flute geometry provides good chip control in through-hole applications. The TiCN coating reduces galling and adhesion when cutting stainless steel, extending tool life in production and maintenance environments. Machinists, tool-and-die makers, and MRO technicians working on light-gauge fastener applications will find this tap appropriate for general-purpose 6-32 thread cutting tasks.

Key Features

• TiCN coating improves wear resistance and reduces built-up edge when tapping stainless steel and cast iron
• Plug chamfer with 3-5 thread lead-in supports through-hole tapping with gradual thread engagement
• H3 thread limit and 2B class of fit deliver consistent tolerance control for standard fastener threads
• 3-flute straight-flute design promotes chip evacuation in through-hole applications
• High-speed steel construction maintains edge integrity across a broad range of ferrous materials
• No coolant-through requirement - compatible with standard hand tapping and low-speed machine tapping setups

Compatibility

Rated for use in cast iron, stainless steel, and steel workpieces. Designed for standard 6-32 UNC through-hole tapping applications where a 2B class of fit is specified.

Installation Notes

This tap is intended for use by machinists or MRO technicians performing hand or low-speed machine tapping operations. Ensure the workpiece is securely fixtured and the correct tap drill size for 6-32 UNC is used prior to tapping. Apply cutting fluid appropriate for the workpiece material, particularly when tapping stainless steel, to reduce heat and galling. Do not exceed recommended feed rates or apply side-loading force, as tap breakage in small-diameter taps is difficult to reverse.
