It features a plug chamfer, which provides a gradual thread lead-in suited for through-holes and deeper blind holes. The tap is ground to an H3 thread limit, offering controlled tolerances for consistent thread fit. Constructed from bright, uncoated high speed steel, it delivers the hardness and wear resistance needed for production tapping in ferrous and non-ferrous materials. Four straight flutes provide chip clearance during hand-tapping operations.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for use in trade and industrial settings where left-hand threads are required, such as machining components that must resist loosening under rotational forces. It is sized for 9\/16-18 UNF thread form and is well suited for use with a standard tap wrench. Machinists, tool and die makers, and maintenance technicians working with threaded fastener repairs or new thread creation will find this tap appropriate for hand-tapping operations in shop and field environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e9\/16-18 UNF thread size with left-hand thread direction for reverse-thread applications\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer provides gradual thread engagement, suitable for through-holes and most blind-hole applications\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit for consistent, controlled thread tolerance\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for hardness and wear resistance across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003e4-flute straight flute design supports chip clearance during hand-tapping\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coolant-through feature, intended for hand-tapping with applied cutting fluid\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or production hand tap for 9\/16-18 UNF left-hand thread applications in metalworking, maintenance, and repair operations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is intended for use by machinists or qualified tradespeople using a tap wrench in hand-tapping operations. Before tapping, ensure the workpiece is securely clamped and the pilot hole is drilled to the correct tap drill size for a 9\/16-18 UNF thread. Apply a suitable cutting fluid to extend tap life and reduce the risk of tap breakage. Left-hand taps must be turned counterclockwise to cut threads — confirm thread direction before beginning to avoid workpiece damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 9\/16-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Straight\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\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eWeight\u003c\/strong\u003e: 0.276 pounds\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: JY4915187\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723040358706,"sku":"JY4915187","price":52.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c8bc3ad479ef3ec3f1354b075fcfd16d.jpg?v=1788599685","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4915187-hand-tap-9-16-18-unf-left-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
