Kennametal 5416932 Spiral Point Tap 1/2-20 Unf Hss-e Ticn

Product Description

The KENNAMETAL 5416932 is a spiral point tap designed for through-hole threading in a wide range of metalworking applications. Built from high-speed steel-E (HSS-E) to the T820 series standard, this tap carries a dual TiCN and TiN coating that extends tool life and reduces friction during cutting. It cuts a 1/2-20 UNF right-hand thread to a 3B class of fit with an H3 thread limit, making it well-suited for production environments where tight tolerance and consistent thread quality are required. Machinists and tool-and-die tradespeople working on steel, stainless steel, cast iron, and non-ferrous metal components are the primary users of this tap.

This tap is suited for through-hole applications in both job-shop and production machining settings. The plug chamfer provides a gradual lead-in that makes it practical for through-hole work on moderate-to-hard workpiece materials. The spiral point geometry pushes chips ahead of the tap rather than packing them into the flute, making it effective on CNC machining centers and manual drill presses where chip evacuation is a priority. Typical installations include threaded fastener holes in structural steel components, stainless steel fabrications, and cast iron housings.

Key Features

• 1/2-20 UNF thread form with right-hand cut and 3B class of fit for close-tolerance work
• H3 thread limit for consistent oversize control within standard tolerance bands
• HSS-E substrate provides added toughness and wear resistance over standard HSS
• Dual TiCN and TiN coating reduces friction and extends cutting life across steel and stainless applications
• Spiral point geometry pushes chips forward, improving chip evacuation in through-hole threading
• Plug chamfer lead-in balances starting ease with cutting efficiency in through-hole setups

Compatibility

Rated for use in steel, stainless steel, cast iron, and non-ferrous metal. Designed for through-hole threading applications. No coolant-through feature; external flood or mist coolant is appropriate where required by the application.

Installation Notes

This tap is installed and driven by licensed machinists or qualified tool operators using standard tap holders, floating tap chucks, or rigid tapping attachments on CNC machining centers or drill presses. Always ensure the workpiece is securely fixtured and the spindle is properly aligned before engaging the tap. Confirm correct tap drill size for 1/2-20 UNF prior to threading to achieve the intended thread engagement percentage. Follow shop safety procedures and applicable OSHA machining standards when operating rotating cutting tools.
