Kennametal 5689850 M6x1 Spiral Point Tap 6H Hss-e

Product Description

The KENNAMETAL 5689850 is a spiral point tap designed for through-hole threading in non-ferrous metal applications. Built from High-Speed Steel-E (HSS-E) and finished with a triple coating of TiN, CrC, and C, this tap delivers consistent thread quality in production and job-shop environments. It cuts a right-hand M6x1 metric thread to a 6H class of fit with a D5 thread limit, producing clean, accurate internal threads suited for precision assemblies. The plug chamfer distributes cutting load gradually at thread entry, reducing tap breakage risk. Machinists, toolroom technicians, and CNC operators handling metric fastener applications will find this tap a reliable choice for high-volume or precision runs.

The 5689850 is intended for through-hole threading operations on non-ferrous metals such as aluminum alloys, brass, and copper. The spiral point design pushes chips forward ahead of the tap rather than packing them in the flutes, making it well-suited for blind-to-through configurations where chip evacuation is critical. With a 2-flute geometry and no coolant-through feature, this tap is typically run with flood coolant or cutting oil in conventional or CNC drilling and tapping setups. It fits standard tap holders and quick-change tapping heads sized for 6.48 mm shank diameter tooling.

Key Features

• M6x1 metric thread, right-hand cut, 6H class of fit with D5 thread limit for precise tolerance control
• HSS-E base material provides increased toughness and wear resistance over standard HSS
• Triple coating: TiN for surface hardness, CrC for lubricity, and C for additional protection in non-ferrous applications
• Spiral point geometry pushes chips forward, supporting efficient chip evacuation in through-hole applications
• Plug chamfer eases thread entry and distributes cutting forces across multiple teeth
• Series T672 with material grade KSMN34, no oversize, no interrupted thread geometry

Compatibility

Designed for through-hole threading of non-ferrous metals. Compatible with standard tap holders and quick-change tapping heads accommodating a 6.48 mm shank diameter. Part of the KENNAMETAL T672 series.

Installation Notes

This tap is intended for installation by machinists and CNC operators using standard tapping equipment. Always secure the workpiece firmly and ensure the tap is properly aligned to avoid tap breakage or thread misalignment. Apply appropriate cutting oil or flood coolant for non-ferrous materials before and during tapping. Follow machine shop safety practices and consult applicable equipment manufacturer guidelines when selecting spindle speed and feed rate.
