Built from high-speed steel (HSS) with a bright\/uncoated finish, it delivers reliable thread cutting in a range of ferrous and non-ferrous materials. The taper chamfer — spanning several leading threads — gradually distributes cutting load, making thread entry smooth and reducing the risk of tap breakage. With 4 flutes and an H3 thread limit, this tap holds close tolerances for a 3B class of fit, which is the standard tolerance for most general-purpose threaded assemblies in commercial and industrial applications.\u003c\/p\u003e\u003cp\u003eThis tap is suited for machining operations in maintenance, repair, and manufacturing environments where 3\/4-16 UNF threads are required. The taper chamfer style is a common first-choice tap for starting threads in open or through-hole conditions. It is typically used in manual tapping with a tap wrench or integrated into a tapping head on a drill press or mill. Right-hand thread direction is standard for conventional threaded fastener applications. Machinists, tool-and-die makers, and maintenance technicians commonly select this tap for production and repair work on equipment components, fluid fittings, and structural fastener applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/4-16 UNF thread size with right-hand thread direction for standard fastener compatibility\u003c\/li\u003e\n\u003cli\u003eTaper chamfer distributes cutting load across multiple leading threads for easier thread start\u003c\/li\u003e\n\u003cli\u003eH3 thread limit ensures consistent tolerance control for 3B class of fit\u003c\/li\u003e\n\u003cli\u003e4 straight flutes provide chip clearance in through-hole and short blind-hole applications\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction supports use across a broad range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish — no added coating layer that could affect thread tolerance in close-fit applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or stock tap for applications requiring 3\/4-16 UNF internal threads to a 3B class of fit tolerance.

Secure the workpiece fully before beginning; use appropriate cutting fluid for the workpiece material to extend tap life and improve thread finish. Confirm the correct tap drill size for 3\/4-16 UNF before drilling to avoid undersized or oversized holes. Never force a tap — back off periodically to break chips and prevent binding or breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-16\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: H3\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: 4.25 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: 0.85 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: K008607AS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51738827489586,"sku":"K008607AS","price":74.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/32648fdba3e897228e3e58ecc68ca18f.jpg?v=1788805132","url":"https:\/\/voomisupply.com\/products\/hertel-k008607as-straight-flute-tap-3-4-16-unf-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
