Built from high-speed steel with a bright, uncoated finish, it delivers consistent thread form at a 3B class of fit with an H4 thread limit. The taper chamfer — typically 8 to 10 threads — eases entry and distributes cutting load across multiple flutes, reducing the chance of tap breakage in harder materials. With 4 flutes and a 4-11\/16 inch overall length, the K008623AS is suited for production and maintenance environments where thread accuracy is required.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in machine shops, maintenance facilities, and field service operations where 7\/8-14 UNF threads are needed in ferrous and non-ferrous metals. The taper chamfer style makes it appropriate as a starting tap in new hole applications or when working with tougher materials that benefit from a gradual thread engagement. It is commonly used in manual tapping, drill press, and light CNC tapping operations where coolant-through tooling is not required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/8-14 UNF thread form for fine-pitch internal threading applications\u003c\/li\u003e\n  \u003cli\u003eTaper chamfer distributes cutting load gradually for easier entry and reduced breakage risk\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides toughness and wear resistance across common workpiece materials\u003c\/li\u003e\n  \u003cli\u003e3B class of fit and H4 thread limit for standard tolerance internal threads\u003c\/li\u003e\n  \u003cli\u003e4-flute straight flute geometry supports chip clearing in through-hole and shallow blind-hole work\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no coating buildup to affect thread tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or stocking tap for any application requiring 7\/8-14 UNF right-hand internal threads at a 3B class of fit. Suitable for use with standard tap wrenches, T-handle wrenches, drill press tapping attachments, and compatible CNC tapping heads that accept straight-shank taps of this size range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the workpiece firmly before tapping and ensure the starting hole is drilled to the correct tap drill diameter for 7\/8-14 UNF threads. Apply appropriate cutting fluid for the workpiece material to reduce heat and extend tap life. For blind holes, clear chips frequently to prevent packing and tap breakage. Coolant-through operation is not supported by this tap.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/8-14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Taper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-11\/16 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: 0.42 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: K008623AS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51731068125490,"sku":"K008623AS","price":114.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/211be34e41bcb120723a29fbf78aa055.jpg?v=1788726541","url":"https:\/\/voomisupply.com\/products\/hertel-k008623as-straight-flute-tap-7-8-14-unf-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
