Built from bright, uncoated high speed steel, this tap delivers reliable cutting performance in manual tapping operations. It features a plug chamfer, which provides a moderate lead-in of several threads, making it well suited for through-holes and most general-purpose tapping tasks. The 4-flute straight flute geometry supports chip evacuation in shorter-chipping materials. With a class of fit of 3B and a thread limit of H3, this tap produces threads that meet standard tolerance requirements for UNS thread profiles. Overall length is 3.375 inches, and the tap weighs 0.12 pounds.\u003c\/p\u003e\u003cp\u003eThis tap is intended for hand tapping operations performed by machinists, maintenance technicians, and tool-and-die professionals working in shop, field, or maintenance environments. It is applied wherever a 1\/2-18 UNS internal thread is required in through-hole applications. The plug chamfer makes it appropriate for starting threads from a pre-drilled hole when tapping through a workpiece rather than into a blind bore. It is typically used with a standard tap wrench and cutting fluid appropriate to the workpiece material.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/2-18 UNS thread standard for specialized thread pitch applications\u003c\/li\u003e\n\u003cli\u003ePlug chamfer provides moderate lead-in suitable for through-hole tapping\u003c\/li\u003e\n\u003cli\u003e4-flute straight flute design promotes chip clearance in short-chipping materials\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction offers durability across a broad range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish allows for easy wear monitoring during use\u003c\/li\u003e\n\u003cli\u003eClass 3B fit with H3 thread limit ensures threads meet standard tolerance specifications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for any application requiring a 1\/2-18 UNS right-hand internal thread cut by hand tapping.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eHand tapping should be performed by a qualified machinist or maintenance technician using a properly sized tap wrench. Always ensure the workpiece is securely clamped and the tap is started perpendicular to the workpiece surface to prevent thread misalignment or tap breakage. Apply an appropriate cutting fluid for the material being tapped. Back the tap out periodically to clear chips and avoid binding.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\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\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\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\u003eOverall Length\u003c\/strong\u003e: 3.375 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: 0.12 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: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: JY4844080\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716854939954,"sku":"JY4844080","price":65.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d117a905a727e9d12ef0d965e7985ff4.jpg?v=1788533097","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4844080-hand-tap-1-2-18-uns-plug-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
