Built from high speed steel (HSS) with a bright, uncoated finish, this tap delivers reliable cutting performance across a range of ferrous and non-ferrous materials. The plug chamfer style features a standard entry lead, making it well-suited for threading through-holes where a gradual start is needed. With 6 flutes, the tap provides adequate chip clearance and cutting stability at this diameter. Overall length is 4 inches, and the part meets Class of Fit 3B with a Thread Limit of H4.\u003c\/p\u003e\n\u003cp\u003eThis hand tap is intended for use in machine shop, maintenance, and repair environments where UNS (Unified National Special) threads are required at the 1-3\/8-14 specification. It is appropriate for use in manual tapping operations with a tap wrench or in low-speed machine tapping setups. The right-hand thread direction and plug chamfer make it a standard production or repair threading tool. Typical installers include machinists, tool-and-die makers, maintenance mechanics, and industrial repair technicians working with custom or non-standard thread specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-3\/8-14 UNS thread form for non-standard unified thread applications\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer provides a gradual thread lead suitable for through-hole tapping\u003c\/li\u003e\n  \u003cli\u003e6-flute straight flute design promotes cutting stability at larger tap diameters\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating buildup to affect thread tolerance\u003c\/li\u003e\n  \u003cli\u003eClass of Fit 3B with H4 thread limit for close-tolerance thread production\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for cutting 1-3\/8-14 UNS right-hand internal threads in through-hole applications.

Ensure the workpiece is securely fixtured and the tap is started perpendicular to the workpiece surface to avoid thread misalignment or tap breakage. Apply appropriate cutting fluid for the workpiece material throughout the tapping operation. Do not force the tap — back off periodically to break chips when tapping deeper holes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-3\/8-14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\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\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\u003eNumber of Flutes\u003c\/strong\u003e: 6\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOversize\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.1 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: JY4872115\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51724003246386,"sku":"JY4872115","price":279.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/32b34c78ac7e07a20bbcc132b6efd37c.jpg?v=1788611381","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4872115-hand-tap-1-3-8-14-uns-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
