Kennametal 5455881 Spiral Point Tap 10-32 Unf Hss-e Ticn

Product Description

The KENNAMETAL 5455881 is a spiral point tap designed for through-hole threading in a 10-32 UNF configuration. It features a plug chamfer, 2 flutes, and a right-hand thread direction with a 2B class of fit and H3 thread limit. The tap is manufactured from High-Speed Steel-E (HSS-E) and carries a dual TiCN and TiN coating for improved wear resistance and tool life. With an overall length of 2.36 inches and a thread length of 0.5 inches, this tap is sized for standard machine threading operations. It belongs to KENNAMETAL Series T820 and is assigned material grade KSP32.

This tap is suited for through-hole threading applications in steel, stainless steel, cast iron, and non-ferrous metals. Its spiral point geometry pushes chips forward ahead of the cutting action, making it well-suited for continuous, through-hole production threading on CNC machining centers, drill presses, and tapping machines. The plug chamfer provides a gradual lead-in, distributing cutting load across several threads for consistent thread quality in typical shop and production environments.

Key Features

• Spiral point geometry drives chips forward, ideal for through-hole threading
• HSS-E base material provides toughness in interrupted and hard materials
• Dual TiCN and TiN coating enhances wear resistance and reduces friction
• Plug chamfer distributes cutting load for smoother thread entry
• H3 thread limit and 2B class of fit meet standard UNF tolerance requirements
• Right-hand thread direction, no coolant-through requirement

Compatibility

Designed for through-hole threading in steel, stainless steel, cast iron, and non-ferrous metals. Suitable for use in standard CNC and manual tapping setups that accept 10-32 UNF taps with a 0.194-inch shank diameter.

Installation Notes

Installation should be performed by a machinist or tooling technician familiar with tapping operations. Ensure the workpiece is securely fixtured and the spindle is properly aligned before engaging the tap. Power down and de-energize any machine before changing or chucking tooling. Use an appropriate tapping fluid or cutting oil suited to the workpiece material to extend tool life and maintain thread quality.
