Built from high speed steel with a bright, uncoated finish, this plug-chamfer tap delivers reliable thread-cutting performance in through-hole and blind-hole applications where chip evacuation is not a primary concern. With 4 flutes and an H3 thread limit, it produces threads within a consistent tolerance class suited to standard fastener fits. The overall length is 3-19\/32 inches, and the tap weighs 0.91 pounds. Right-hand cutting direction is standard. This tool is intended for use by machinists, toolmakers, and maintenance technicians in production and repair environments.\u003c\/p\u003e\u003cp\u003eThis tap is suited for general-purpose threading operations on ferrous and non-ferrous metals where a plug chamfer entry is appropriate. The plug chamfer — typically 3 to 5 threads of lead — makes it a versatile starting tap for most through-hole applications and for continuing threads started with a taper tap in blind holes. It is commonly used in manual tapping, CNC machining centers, and drill press setups. Coolant-through is not supported, so external cutting fluid application is recommended when tapping harder materials to extend tool life and improve thread finish.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e9\/16-12 UNC thread form for standard inch-series fastener compatibility\u003c\/li\u003e\n\u003cli\u003e4 straight flutes for rigidity and predictable chip control in shorter-chipping materials\u003c\/li\u003e\n\u003cli\u003ePlug chamfer provides a versatile lead suitable for most through-hole and some blind-hole work\u003c\/li\u003e\n\u003cli\u003eH3 thread limit for consistent tolerance in standard-fit threaded assemblies\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction offers a good balance of toughness and wear resistance\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish allows easy visual inspection for wear\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-shank replacement or production tap for equipment and fixtures accepting 9\/16-12 UNC plug taps with a straight flute geometry.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed by qualified machinists or maintenance technicians using a tap wrench, tapping head, or CNC rigid-tapping spindle. Before tapping, ensure the workpiece is securely clamped and the correct tap drill size for 9\/16-12 UNC has been used to prepare the hole. Apply cutting fluid appropriate to the workpiece material throughout the operation. Inspect the tap for chipping or wear before each use, and never force a tap that has stopped rotating, as breakage and workpiece damage may result.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 9\/16-12\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: 4\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: H3\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: 3-19\/32 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: 0.91 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: K008545AS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51737409716530,"sku":"K008545AS","price":63.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8eb969b2ec21db8e0b9e877784c8f542.jpg?v=1788788198","url":"https:\/\/voomisupply.com\/products\/hertel-k008545as-9-16-12-unc-plug-tap-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
