Kennametal 4131262 Spiral Point Tap 6-32 Unc Hss Ticn

Product Description

The KENNAMETAL 4131262 is a spiral point plug tap designed for threading 6-32 UNC holes in production and maintenance machining environments. Built from high speed steel (HSS) with a titanium carbonitride (TiCN) coating, it delivers increased surface hardness and lubricity compared to uncoated taps, extending tool life in abrasive and tough-to-machine materials. The plug chamfer distributes cutting load across the first few threads, making it well suited for through-hole tapping applications. With a 2-flute geometry and a right-hand thread direction, this tap pushes chips forward ahead of the cut, keeping the flutes clear during operation. Overall length is 2 inches with a thread length of 11/16 inches.

This tap is intended for threading 6-32 UNC through holes in cast iron, ductile iron, stainless steel, and steel workpieces. It is used in CNC machining centers, drill presses, and hand-tapping operations across manufacturing, toolroom, and MRO settings. The H3 thread limit and Class 2B fit make it appropriate for standard-tolerance threaded fastener applications. Machinists, tool-and-die makers, and maintenance technicians are the primary users of this tap size and geometry.

Key Features

• TiCN coating improves wear resistance and reduces built-up edge in ferrous materials
• Plug chamfer (3-5 thread lead) distributes cutting load for smooth through-hole threading
• Spiral point geometry pushes chips forward, reducing chip re-cutting and tap breakage
• H3 thread limit holds Class 2B fit tolerances for standard fastener thread forms
• Right-hand cut, 2-flute design compatible with standard tapping attachments and CNC rigid tapping cycles
• No coolant-through requirement simplifies setup on standard equipment

Compatibility

Designed for tapping 6-32 UNC threads in cast iron, ductile iron, stainless steel, and steel. KENNAMETAL Series 5301S. Suitable for use with standard 6-32 tap holders and collet-style tapping chucks sized for a 0.141-inch shank diameter.

Installation Notes

Installation and use should be performed by a qualified machinist or maintenance technician familiar with tapping operations. Always ensure the workpiece is securely fixtured and the spindle is properly aligned before beginning the tapping cycle. For hand tapping, use a calibrated tap wrench and apply appropriate cutting fluid for the workpiece material. Inspect the tap for chipping or wear before each use, and never force a tap that has stopped advancing, as breakage and workpiece damage can result.
