Built from High-Speed Steel-E (HSS-E) in the KSP39 material grade and finished with an oxide coating, this tap delivers reliable performance in demanding cutting conditions. It features a 1\/2-20 UNF thread size with a right-hand thread direction, 3 flutes, and a plug chamfer for smooth thread entry. With an overall length of 3.375 inches and a thread length of 0.9375 inches, it fits standard tap holders used in machine shop and production environments. This tap is engineered for machinists and tooling specialists working with ferrous and cast materials.\u003c\/p\u003e\u003cp\u003eThe 5416937 is suited for through-hole threading applications in steel, stainless steel, and cast iron. The spiral point geometry pushes chips forward ahead of the cutting action, making it well-matched for through-hole work on CNC machining centers, drill presses, and tapping machines in both production and job-shop settings. The H7 thread limit ensures consistent fit tolerances across threaded holes in precision assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSpiral point geometry pushes chips ahead for clean through-hole threading\u003c\/li\u003e\n\u003cli\u003eHSS-E construction with oxide coating for improved wear resistance and heat tolerance\u003c\/li\u003e\n\u003cli\u003ePlug chamfer provides gradual thread entry and controlled cutting force\u003c\/li\u003e\n\u003cli\u003eH7 thread limit for consistent tolerance in precision threaded holes\u003c\/li\u003e\n\u003cli\u003eRight-hand, 1\/2-20 UNF thread form for standard unified fine-thread applications\u003c\/li\u003e\n\u003cli\u003eCompatible with steel, stainless steel, and cast iron workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for through-hole threading in steel, stainless steel, and cast iron.

Power down or de-energize the machine before changing tooling. Use appropriate cutting fluid or coolant for the material being threaded to maximize tool life and thread quality. Follow machine manufacturer torque and speed recommendations for the tap diameter and material application.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-20 UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Spiral Point\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: HSS-E (KSP39)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.9375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.800 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.367 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 0.05 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T820\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5416937\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51727920660786,"sku":"5416937","price":86.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/861d04fdd0d65732ca5807df8952d8d4_024b0df6-9cff-4274-8b33-8d8897edf483.jpg?v=1788684553","url":"https:\/\/voomisupply.com\/products\/kennametal-5416937-spiral-point-tap-1-2-20-unf-hss-e","provider":"Voomi Supply","version":"1.0","type":"link"}
