Built from high-speed steel (HSS) with a bright, uncoated finish, it features a plug chamfer and 2 flutes. The spiral point geometry pushes chips forward ahead of the tap, making it well suited for threading through-holes where chips can exit freely. The H11 thread limit indicates a tight tolerance class appropriate for precision threading work. This tap runs right-hand direction and does not require coolant-through capability.\u003c\/p\u003e\n\u003cp\u003eThis tap is commonly used in machine shops, manufacturing facilities, and industrial maintenance settings where 1\/4-20 UNC threads are required in through-hole applications. It is appropriate for use in soft to medium-hardness materials. The plug chamfer provides a gradual lead-in, distributing cutting load across several threads and allowing the tap to start cleanly. It is sized to produce oversize threads by 0.005 inches, a characteristic noted in the specifications for this part.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC thread size for standard fractional through-hole tapping\u003c\/li\u003e\n  \u003cli\u003eSpiral point design pushes chips forward, reducing clogging in through-hole applications\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides durability across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer for smooth lead-in and distributed cutting load\u003c\/li\u003e\n  \u003cli\u003eH11 thread limit for close-tolerance threading requirements\u003c\/li\u003e\n  \u003cli\u003eOversize by 0.005 inches to compensate for springback in applicable materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use spiral point tap for standard 1\/4-20 UNC through-hole tapping operations in production and maintenance environments.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap should be installed in a machine or hand tap holder rated for the shank size and used with appropriate tapping fluid or cutting oil for the workpiece material. Ensure the workpiece is securely clamped and the tap is properly aligned before beginning the threading operation. Do not reverse the tap without adequate chip clearance to avoid breakage. Follow applicable shop safety procedures and machine tool guidelines when operating powered tapping equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: H11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOversize\u003c\/strong\u003e: Yes, 0.005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.38 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: K008337AS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51733086601522,"sku":"K008337AS","price":25.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/54a93fda1218534ddea00b2a3a884a14.jpg?v=1788751214","url":"https:\/\/voomisupply.com\/products\/hertel-k008337as-spiral-point-tap-1-4-20-unc-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
