Kennametal 5431732 Spiral Point Tap M14x2 3 Flute 6H Hss-e

Product Description

The KENNAMETAL 5431732 is a spiral point tap designed for through-hole threading in metalworking applications. It cuts an M14x2 metric thread profile with a 3-flute, plug chamfer geometry that pushes chips forward ahead of the cutting zone, keeping the flutes clear during the operation. Built from HSS-E (high-speed steel with cobalt), the tap carries an oxide coating for added lubricity and corrosion resistance. Overall length is 3.59 inches with a 1-inch thread length and a shank diameter of 0.429 inches. Material grade is KSP39. This tap is suited for use by machinists and tool-and-die professionals working in production or maintenance environments.

This tap is intended for through-hole threading operations on steel, stainless steel, and cast iron workpieces. The spiral point geometry makes it well suited for continuous-feed applications on CNC machining centers and manual drill presses where through-holes allow chips to clear freely. The 6H class of fit is a standard tolerance class used in metric threading for general-purpose fastener applications. Series T820 with a D7 thread limit supports consistent thread quality across production runs.

Key Features

• M14x2 metric thread profile with 6H class of fit for standard general-purpose tolerance
• 3-flute spiral point geometry pushes chips forward in through-hole applications
• HSS-E (cobalt-enriched high-speed steel) construction for improved heat and wear resistance
• Oxide coating improves lubricity and reduces friction during cutting
• Plug chamfer eases entry and reduces torque at thread start
• Right-hand thread direction; no coolant-through capability

Compatibility

Designed for through-hole threading in steel, stainless steel, and cast iron. Fits standard tap holders and chucks accepting a 0.429-inch shank diameter. Intended for applications requiring an M14x2 metric thread with a 6H tolerance class.

Installation Notes

This tap should be installed by a qualified machinist following standard tapping procedures. Ensure the workpiece is securely fixtured and the spindle is properly aligned before engaging the tap. Apply appropriate cutting fluid for the workpiece material to extend tool life and maintain thread quality. Always back the tap out periodically to clear chips if tapping in interrupted or blind conditions, even though this tool is optimized for through-hole use.
